Research to Implementation: Design and Evaluation of Scour for Bridges Using HEC-18

This Research to Implementation video presents an example of NJDOT-sponsored research and the effect such research has in addressing transportation-related issues within the State.

Bridge scour is the removal of sediment such as sand and gravel from around non-tidal bridge substructures and supports caused by swiftly moving water. This water can scoop out ​scour holes​, compromising the integrity of a structure. Understanding the extent of bridge damage and prioritizing the order of repair is critical to maintaining safe bridges.

With the support of NJDOT's Bureau of Research, researchers developed the NJ-specific Scour Evaluation Model (SEM) to prioritize bridges for repair. The SEM model was determined to be effective and is now approved by FHWA and NJDOT to evaluate scour risk. The project included training of consultants to encourage the expanded use of the SEM model in NJ.

The video promotes the benefits of funded research to increase the safety of the traveling public, reduce costs, and increase efficiency.

NJ STIC Innovations Featured at EDC-6 Virtual Summit

On December 8-10, 2020 FHWA hosted the Every Day Counts (EDC) 2020 Virtual Summit.

EDC is a State-based model that promotes the identification and rapid deployment of proven, yet underutilized innovations to shorten the project delivery process, enhance roadway safety, reduce traffic congestion, and integrate automation. FHWA works with State transportation departments, local governments, tribes, private industry and other stakeholders to identify a new collection of innovations to champion every two years that merit accelerated deployment.

The Summit is an integral component of the EDC model, bringing together transportation leaders and front-line professionals responsible for the development and delivery of highway projects to learn more about the innovations. Following the Summit, the States finalize their selection of innovations, establish performance goals for implementation over the upcoming two-year cycle, and begin to implement the innovations with the support and assistance of the technical teams established for each innovation.

The EDC-6 Summit was conducted virtually and included over 3,000 attendees from state Departments of Transportation, local agencies, federal land management agencies, tribes and industry. In the EDC-6 two-year cycle, seven innovations were featured that promote strategies to increase engagement with people, new applications of products to preserve and repair infrastructure, and improved processes that can save time on project delivery and incident management.

The EDC-6 Virtual summit included an exhibit pavilion to showcase home-grown innovations that State Transportation Innovation Council (STIC) members developed and implemented. The purpose of the pavilion was to celebrate and share examples of innovations that save lives, time and resources with a wider audience to expand their potential use and impact. Highlighted innovations did not need to be EDC-related, or previously funded through the STIC Incentive or AID Demonstration grant programs. Rather, exhibitors were asked to share those innovations that could benefit other state and local agencies.

The NJ STIC selected the ten innovations shown here for the pavilion.

NJDOT Tech Talk! Webinar – Research Showcase: Lunchtime Edition

On April 22, 2021, the NJDOT Bureau of Research hosted a Lunchtime Tech Talk! webinar, “Research Showcase: Lunchtime Edition!”. The event featured three important research studies that NJDOT was not able to include in the NJDOT Research Showcase virtual event held last October. The Showcase serves as an opportunity for the New Jersey transportation community to learn about the broad scope of academic research initiatives underway in New Jersey.

The three projects examined various issues in transportation from surface transportation vulnerability to climate change, to the impacts of lighting on work zone safety, to policies that regulate overweight trucks in New Jersey. After each presentation, webinar participants had an opportunity to pose questions of the presenter.

Quantifying Impacts of Disruptive Precipitation to Surface Transportation: A Data-Driven Mitigation Approach. Raif Bucar is a third-year Engineering Management Ph.D. student at Stevens Institute of Technology, currently conducting research on surface transportation vulnerability to flood events. The study adopts a multidisciplinary approach to look at the effects of not only 100 and 500 year floods, but also more frequent events that cause local flooding to assess the impact on mobility and accessibility in Hoboken, NJ. The resulting study explores flooding impacts on the transportation system in terms of mobility and accessibility metrics and can inform the flood mitigation measures and measures to improve resilience.

The study used a traffic simulation model to look at storm magnitude and high and low tide in relation to Vehicle Miles Traveled, Vehicle Hours Traveled, and Trips Completed. Mr. Bucar described analysis of data to predict flood risk and determine areas of higher probability of flooding by year-storm and tide to determine why some areas flood more often than others. The study explored urban characteristics including land cover and topography, elevation, slope, impervious coverage, and drainage system features, and looked at the correlation of these features with flooding.

Mr. Bucar described the application of this information to determine routing information for drivers by applying machine learning to develop a “most valuable path” that adjusts travel time based on each link in the route and diverts drivers in response to changing conditions during flood events. The study findings can also be applied to guide flood resilience transportation planning. Future work will look at other models to validate this study’s assumptions, and will investigate driver behavior during flood events and how drivers respond to new information.

Following the presentation, Mr. Bucar responded to questions asked through the chat feature:

Q. There is not as much research on rainfall-induced flooding. Why not?
A. There may be resistance to using interdisciplinary approaches to exploring this problem. This is an area that needs more research as the disruptive effects of flooding on transportation mobility is increasingly apparent.

Q. How translatable is this approach to other cities or locations?
A. Thus far, we have not applied the framework to other areas, but should be able to apply it to other controlled study areas. A study of larger areas, such as a state, will not show local differences. There is a limit to how much we can scale this model.

Q. How do you plan on factoring in driver behavior and driver knowledge of flood events in future studies?
A. We anticipate using surveys and controlled experiments.

Lighting, Visual Guidance and Age: Importance to Safety in Roadway Work Zones. Dr. John Bullough is the Director of Transportation and Safety Lighting Programs and a Course Instructor in the graduate program in lighting at the Lighting Research Center at Rensselaer Polytechnic Institute.

Work zones are complex visual environments, and particularly so at night when illumination is needed for workers to complete tasks and for drivers to see the work area and understand how to navigate around it. Roadway delineators, and steady and flashing lights used in work zones can cause glare and visual chaos that affect drivers’ ability to see well. These challenges are exacerbated for older drivers due to physical changes in the eye over time.

Dr. Bullough described the Relative Visual Performance (RVP) model used to look at the speed and accuracy of visual processing in relationship to light level, the contrast between an object and the background, the size of an object, and the age of the observer. The research compared the effects of: steady lighting; flashing lights at night and during the day; sign retroreflectivity, color, and lettering; and road delineators on younger and older drivers.

Dr. Bullough noted that, with an aging driving population, the needs of older drivers should be considered to improve road safety around work zones. Study conclusions emphasize that older drivers need higher light levels than younger adults, but warns that higher light levels can create more glare. There is a need for flashing warning light intensity specifications that reflect the needs of drivers of all ages. It was noted that higher reflectivity in sign sheeting can extend legibility distances and so assist older drivers. Dr. Bullough noted that monitoring of light levels is needed throughout their use to keep levels of glare low.

Several questions were posed to Dr. Bullough after his presentation:

Q. Was the information broken down for age groups over 60 years?
A. Optical changes continue to ages 70 and 80. However, there are other potential visual problems among individuals in these age groups – for example, cataracts, macular degeneration, and glaucoma which make generalizations more difficult.

Q. Does the color of light affect glare and visibility?
A. It depends on what we mean by “glare”. Red and blue lights – which we might find on police and flashing lights of highway maintenance trucks – have the same contrast-reducing characteristics regardless of color. However, people tend to be more sensitive to bluer colors; they find them much brighter, more glaring, more annoying and distracting even if they do not affect visibility any more than red or yellow lights of the same intensity. So, depending on what we mean by glare – if it’s that sensation of pain or annoyance – color matters a lot; if it is just visibility than it really comes down to candle-power, or candelas.

Q. What were the overall differences between urban and rural environments?
A. Urban environments tend to be more difficult for all drivers to find key information in the visual clutter. However, the effect is still much harder for older people than young people.

Q. How does eye recovery after glare differ between younger and older people?
A. Eyes in older people take twice as long to recover (3-4 seconds) after exposure to glare than in younger people.

Analysis of Overweight Truck Permit Policy in New Jersey. Dr. Hani Nassif is a professor at Rutgers, The State University of New Jersey, where he has established the Bridge Engineering Program.   Dr. Nassif introduced the study and acknowledged the contribution of the research team that worked on this study and a prior study focused on the impact of freight on pavement and bridge infrastructure.

This research study explored whether New Jersey’s scheduled permit fees for overweight trucks allow NJDOT to recover all or part of the costs of the damage imposed by these vehicles traveling on NJ roads and bridges.

In a previous study, researchers had correlated truck overweight data with damage to bridges and pavements which showed higher rate of deterioration with higher rates of use by overweight trucks. The main question for this study considered whether the permit fees were sufficient to recover the costs incurred on the infrastructure. Then, in light of these findings, what policy recommendations could be made to change permit policies.

Dr. Nassif described various data sources and methods that were used to estimate the costs of damage to roads and bridges caused by overweight vehicles, including six years of data from the NJ Overweight Permit Database, Straight Line Diagrams of the NJ roadway network, GIS and the National Bridge Inventory including bridge location and conditions.

Dr. Nassif also provided an overview of NJ Overweight Permits, explaining the various types, validity, fee schedule and weight rules.  He highlighted the challenges of effectively collecting fees for overweight trucks and use categories for which fees are not adequately collected.   If a truck weighs more than 80,000 lbs., a permit should be obtained. Although, the State issues 100,000 permits each year, 96 percent of overweight trucks are estimated to be running without permits. These are not short hauls; the trip length is, on average, 50 miles.

The study also looked at fee permitting across the country. Each state uses one of three different permit fee structures: a flat fee; an oversize, overweight fee; and a new model which combines oversize, overweight, and mileage. The study included an effort to benchmark New Jersey against other states in terms of its fee structure. NJ is fourth highest in terms of overweight fee structure.  Any revised policy must take into account these higher fees in relation to neighboring states.

Dr. Nassif noted that the study findings can inform discussion of alternative policies on trucking fees.  The State can maintain the same fee schedule, add mileage to the fee calculation, or charge a flat fee. Dr. Nassif noted that it is not the objective of the state to recoup all the damage costs but perhaps to try to have all sectors of the economy pay their share in terms of the damage to the infrastructure. He suggested that, because trucks using more than six axles cause less damage, the use of more axles could be incentivized. Fees in NJ are already high, so an increase may not be feasible. All sectors of the trucking industry should pay their fair share.  There may be greater efficiency and equity in imposing a permit fee structure that collects a greater fee for longer mileage trips.

Dr. Nassif answered several questions following his presentation: 

Q. What would be your recommendation for regulating overweight trucks- to change to a flat fee or a mileage-based fee?
A. A combination of overweight and mileage fees might be most appropriate in NJ for a fair distribution of permit fees. This is similar to neighboring states. The average trip length is 50 miles for a permit. If a truck travels more, the State could add $1 for each additional mile would recoup 80 percent of the damage cost.

Q. Have you considered the cost of compliance in payment of fees for overweight vehicles?
We have been trying to work with the trucking association – we had a couple of workshops with stakeholders from agencies and trucking association – with the overall goal of enhancing the movement of goods. For example, the state could incentivize the use of a larger number of axles by lowering fees for these trucks. Truck weight enforcement is currently inefficient – it’s like chasing “cat and mouse”. Permits are not obtained for most overweight vehicles. Autonomous enforcement using accurate sensors along the road could result in citations and force drivers to get overweight permits. Weigh-in-Motion stations could be used as enforcement stations.

The enforcement needs to be more effective and we need more legislation; this legislation is under consideration in NY. NJ should consider this legislation to generate more revenue, and provide an equal footing for all parts of the trucking industry.

Q. With regional partners working together would we see more compliance?
A. There have been some regional efforts, including the Port Authority of New York and New Jersey calling for harmonizing the permitting process across state lines. New Jersey and New York could take the lead in advancing legislation to create a unified approach from Connecticut to Delaware and Maryland.

A recording of the webinar is available here.

What Do Autonomous Vehicles Mean for Infrastructure?

PAVE April 14, 20201 Virtual Panel Highlights

On April 14, 2021, Partners for Automated Vehicle Education (PAVE) hosted a virtual panel on the timely topic of “What Do AVs Mean for Infrastructure?” Formed in 2019, PAVE is a coalition of industry, academic and non-profit institutions that focuses on educating the public and policymakers on Autonomous Vehicle (AV) technology.

The April 14th virtual panel offered a facilitated discussion among three professionals on infrastructure-related opportunities and challenges related to AV. Participants included the following:

  • Michele Mueller, Senior Project Manager Connected and Automated Vehicles, Michigan DOT
  • Avery Ash, Head of Autonomous Mobility, INRIX
  • Robert Dingess, President, Mercer Strategic Alliance

The panel shared that stakeholders are working to determine a hierarchy of infrastructure needs and priorities related to AV technology. Several infrastructure undertakings related to pavement markings that could help advance the use of AVs include the addition of dotted edge line extensions on exit ramps and expansion of roadway markings from four to six-inches. It was remarked, however, that it would be cost prohibitive for state Departments of Transportation (DOTs) to regularly update pavement markings. Thus, other strategies to help facilitate appropriate AV identification of lane markings should be investigated. As one panelist noted, AV technology needs to be adaptable to the reality that pavement markings will not always be consistent or new.

The panel discussed possibilities for using AV data to help create and monitor digital infrastructure, which could help agencies understand where to prioritize improvements, ultimately benefiting roadway users. Issues to be determined include how DOTs can best access this data and cost factors. One possibility noted by Ms. Mueller would be development of a business model that promoted a two-way data exchange among DOTs and AV data sources.

Discussion concluded with a recommendation that DOTs and other stakeholders explore the Notice of Proposed Amendments for the 11th edition of the Manual on Uniform Traffic Control Devices (MUTCD), which is available for public comment in the Federal Register. As the national standard on traffic control devices, the MUTCD plays a vital role in fostering interstate infrastructure uniformity. The recently released FHWA-proposed MUTCD updates include a Part 5 section on automated vehicles, which offers an excellent opportunity for DOTs and other interested parties to share comments and feedback on the topic of AV and infrastructure priorities and needs.

Next-Generation TIM: Integrating Technology, Data, and Training

What is Next-Generation TIM: Integrating Technology, Data, and Training?

New methods for improving Traffic Incident Management (TIM) programs aim to increase traveler and responder safety and improve trip reliability and commerce movement on all roadways.

Over 6 million reportable crashes occur every year in the United States. Each crash places responders and motorists at risk of secondary crashes while having a severe impact on congestion. New tools, data, and training mechanisms can be used to improve safety and reduce clearance times at roadway crashes. New and existing TIM programs, including those for local agencies and off-interstate applications, will benefit from using enhanced TIM practices on all roadways to save lives, time, and money.

A New Generation of TIM

While the FHWA's national TIM responder training program successfully trained almost 500,000 responders to clear incidents collaboratively, safely, and quickly, it was largely focused on agencies that respond on interstates and high-speed roadways. Next-generation (NextGen) TIM increases the focus on local agency TIM programs while integrating new and emerging technology, tools, and training to improve incident detection and reduce safety response and clearance times on all roadways.

Traditionally, transportation agencies capture incidents (crashes, roadway debris, stalled vehicles on mainlines, etc.) where sensor technologies are installed, where safety service patrols are present, or when contacted by public safety/law enforcement agencies. NextGen TIM significantly expands this capacity. It enables agencies to improve TIM strategies by implementing new options such as back-of-queue warning, navigation-app notification of active responders in the vicinity, notification-based incident detection using crowdsourced data, and more.

By using NextGen TIM methods, State and local agencies can increase traveler and responder safety, improve trip reliability and commerce movement, and enable responder communities to focus more resources on other pressing citizen needs.

Benefits

Increased Safety. NextGen TIM targets advances in safety through engineering, enforcement, education, and emergency services to help keep responders, drivers, and pedestrians safe across freeway, arterial, and multimodal travel.

Improved Travel Times. Training, data, and technology combine to help local and State agencies reduce secondary crashes and clearance times, improving trip reliability and increasing motorists' awareness of active responders along their travel routes.

Improved Operations. Integrating new and emerging technology, tools, and training can improve incident mitigation and safety throughout the whole TIM timeline, from incident detection to clearance on all roadways.

How NJ Incorporates NextGen Traffic Incident Management (TIM)

Stage of Innovation:
DEVELOPMENT
(December 2022)

Research. NJDOT is coordinating with State Police to determine communications that will be shared with Computer-Aided Dispatch (CAD) integration. NJDOT is also working to establish radio channels to enable coordinated DOT and law enforcement communications at incident sites.

Training. NJDOT is actively working towards achieving participation by all local agencies in the NJDOT established statewide TIM training course.

Building Support. DVRPC area-generated incident management task forces can serve as models for creation of similar diverse stakeholder task forces in other regions. NJDOT is also looking to build partnerships with media to facilitate TIM communications.

What’s Next?

For the EDC-6 initiative, the NJDOT initially wanted to focus on CAD integration as one of the major activities in support of the TIM strategic plan. As a result of NJ State Police's decision to change their CAD technology, the NJDOT is revising their approach for EDC-6 NextGen TIM.

NJDOT is continuing to coordinate with the NJIT ITS Resource Center to deploy HAAS Alert technology on NJDOT's Safety Service Patrol vehicles. The responder-to-vehicle alert application will deliver incident alerts to the motorists (i.e. phone apps) for their situational awareness when approaching a stopped SSP vehicle assisting stranded motorists to assist in reducing speed and collision.

The NJSP statewide CAD system (Motorola FLEX) is currently being re-evaluated. The NJDOT will continue to maintain the existing working group/team comprising staff from the Mobility Operations, Mobility Planning/Research, and NJIT ITS Resource Center to provide coordination and strategic planning for the CAD integration project.

e-Ticketing

Implementing e-Ticketing, and the related practice of using digital as-builts, into project delivery enhances safety, quality, and cost savings by improving the accessibility of project data.

Highway construction projects produce massive amounts of valuable data. Historically, information such as materials tickets and as-built plans were communicated via paper. Today's transportation agencies are improving on these paper processes by integrating them into electronic and digital workflows. Electronic ticketing (e-Ticketing) improves the tracking, exchange, and archiving of materials tickets. Digital information, such as 3D design models and other metadata, can enhance the value of contract documents and the future usability of the as-built plans for operations, maintenance, and asset management. Both can increase project safety and quality through efficient data gathering and sharing.

What is e-Ticketing?

Providing all stakeholders with an electronic means to produce, transmit, and share materials data and track and verify materials deliveries enhances safety, streamlines inspections, and improves contract administration processing. Using electronic ticket (e-Ticket) exchanges enables access via mobile devices and simplifies handling and integration of material data into construction management systems for acceptance, payment, and source documentation.

Benefits

Safety. e-Ticketing enhances data collection while reducing exposure to adjacent vehicular traffic and construction equipment for inspectors and work crews while retrieving paper tickets.

Time Savings. Real-time access, via electronic handling of tickets, reduces processing time for quality assurance and payment, decreasing the inherent delays in paper-based project administration.

Quality. Project documentation is more consistent and efficient using e-Ticketing platforms. Standardized data enables archiving for future reference, leading to improved design, construction, maintenance, and operations.

How NJ Incorporates e-Ticketing

Stage of Innovation:
DEVELOPMENT
(December 2022)

New Jersey has taken several steps to advance its use of e-Ticketing and to encourage its partners to adopt its use.

Research. NJDOT has collected and reviewed information, guidance, research, and best practices on the implementation and use of e-Ticketing techniques.

Training. NJDOT has participated in e-Ticketing trainings, peer exchanges, and workshops.

Building Support. NJDOT is working with internal and external partners, stakeholders, and vendors to advance the use of e-Ticketing. The agency has also identified individuals for an implementation team.

What’s Next?

A NJDOT e-Ticketing working group was formed that will work to advance this innovation by pursuing tasks including seeking guidance from other state DOTs on their e-Ticketing related interactions with vendors and procedures and policies. The working group is at the stage in the process where a "Project Intake Process" and "Project Risk and Complexity Assessment Tool" is being developed.  The team in place includes a designated individual assigned as the lead following completion of a procurement process.

The working group is coordinating with the DOT for preparation and submission of Logical SAR (System Architecture Review) documents which are required to select an e-ticketing Vendor and the necessary software.

Innovation Spotlight: NJDOT UAS Program

The Federal Highway Administration has encouraged State Departments of Transportation to utilize Unmanned Aerial Systems (UAS), sometimes known as “drones”, to improve operations, construction, inspection, and safety by collecting data needed to design, build, and operate the highway system.

The NJDOT UAS Program has been a leader among state DOT UAS programs.  Several articles and a video have already featured the program origins, equipment and training needed to build capacity, and establish “use cases” for the integration of UAS technology within various NJDOT operations.  Glenn Stott, Program Manager, NJDOT Aeronautics & UAS, has been instrumental in standing up the UAS Program.  In this interview, we asked Glenn to provide an update on how the UAS Program has been deployed on recent projects.  Below is an edited summary of our interview and follow-up discussion.

How has the UAS Program been using its recent STIC incentive funding?

The UAS program really benefited from STIC funding at its start. The funding paid for the equipment to fly the missions and deliver regulation and procedures training to staff.  Two phases of training were devoted to legal and regulatory issues, and hands-on training, common to all state agencies. The third phase was mission-specific, exploring how drones could be used for infrastructure inspections and mapping projects. The training helped us build our agency’s capacity to work with UAS, strengthen our working relationships with other state agencies, and raise our awareness of regulatory compliance issues.

We received a second round of STIC funding to pay for equipment, but the Buy America program requirements have been a challenge to procuring equipment.  When we were defining our specifications for the new equipment, we were looking at technical capabilities, not national origin. We have also tried to stay with software similar to what we already have used for training and standardization purposes.

 Can you tell us how the UAS Program has functioned on NJDOT projects?

At NJDOT, our divisions are new to UAS and have their own methodologies that have been successful for decades. We have to find ways to merge our methodologies with theirs and assure them of a high level of success before they will agree to employ UAS.

UAS Team in the field exploring the damage from rockfall along I-287

UAS has played an in-house consultant role on many projects, including several rockfall projects. There are 400 rockfall areas along NJ roadways. NJDOT’s Geology and Capital Program Management (CPM) have been working diligently to analyze the areas and come up with viable solutions and prevent incidents. We flew 49 different sites along Route 15 to gather rockfall data and supported several projects along I-80.

I think we were particularly effective on the I-80 project in the vicinity of the Delaware Water Gap, a national park.  Outside consultants were unfamiliar with federal regulations, and the National Park Service (NPS) representatives were concerned about the use of drones on park property. We are not able to fly a drone from national park property. In this case, the drone was taking off from, and landing on, state property next to the highway. Although the NPS had no formal authority over airspace in this case, we wanted to be good neighbors and address any concerns they might have, particularly related to wildlife areas, and elicit their help in developing the mission profile. With our regulatory experience and knowledge of aviation laws, we developed a mission profile that complied with regulations and was acceptable to all parties.  A consultant flew the mission and we were onsite.

Along I-80, we had particularly challenging conditions in which to work.  In this case, the road has three lanes in each direction with a concrete median, no ditch and no right of way, and rock walls on both sides of the road. We do not fly over active roadways. We had to shut down the left lane in one direction and fly from the left lane. We knew this work had the potential to create road congestion and a distraction for drivers. We coordinated with our NJDOT Bureau of Safety to come up with a flight plan, a take-off and landing area, position of staging vehicles, and plan for support of safety vehicles. These types of projects take a lot of coordination. A consultant flew the mission but NJDOT UAS staff were on site. Although we want to be in the forefront of UAS development, we do not want to risk safety. The Department needs to be comfortable with the comprehensive process of developing the mission profile.

For NJDOT Multimodal, we have assisted with a number of rail projects funded through our rail freight assistance grants program. We fly our own UAS for project management to document existing conditions pre-construction, monitor during construction, and document post-construction to show how taxpayer money has been used. One project, about six months ago, was an NJDOT grant to work with Conrail on the Waverly Loop rail construction project. The Waverly Loop is intended to allow trains to reverse direction by following a teardrop track.

Conrail could not find a consultant to fly the project. The location is challenging as it lies across the NJ Turnpike from Newark Airport and was in the front yard of the state prison, and involves several environmental, wind, and traffic concerns.  We needed to coordinate with the FAA [Federal Aviation Administration], but we are familiar with their concerns and have operated in Newark Class B airspace many times. The agency has a Certificate of Authorization (COA) with all controlled airports in the state as well as with the Philadelphia International Airport.  In this case, we also needed to coordinate with the NJ Department of Corrections. We need to know the players and the regulations. On this project, NJDOT was the consultant and our UAS staff flew the project. We had to ensure that the mission profile and plan met regulatory requirements, the restrictions of the COA, Conrail and Multimodal objectives, and kept all the parties satisfied and informed. We are just one piece of making the project come together.

We have done a lot of work with the NJDOT Office of Maritime Resources, for pre-, during, and post-construction on dredging and other projects. Recently, we flew drones to make sure pipelines were not disturbed during construction in the marshlands near Atlantic City. We also had to prove compliance with NJDEP wetland restrictions when electrical poles were placed by helicopter in this area because dozers and heavy equipment cannot be used.

How has UAS been used for transportation planning and environmental projects?

Drones were used to inform a Concept Development Study of traffic congestion on Route 9 Northbound at the ramp to the Garden State Parkway.

Drones were used to inform a Concept Development Study of traffic congestion on Route 9 Northbound at the ramp to the Garden State Parkway

Two years ago, we worked with construction project management to help them address congestion along Route 9 at the entrance to the Garden State Parkway North to address commuter complaints. Usually, a crew would go out to the site to monitor traffic flow over a period of time. We scouted locations for take-off and landing and suitable vantage points to capture images of the entire road segment. We sent two drones up to take video footage. Reviewing the video, the project management team could quickly determine the source of the congestion. The project manager appreciated that the “eye in the sky” saved a lot of time in determining the problem, and the video helped to explain the issue to contractors and NJDOT supervisors.

We still need the right equipment to demonstrate how drones can support bat counts under bridges. There are nine species of bats in the state that are either federally-protected or state-protected. DEP regulations state that we cannot interfere with them during certain life stages such as migration and hibernation. Coordination with US Department of Fish and Wildlife and NJ Division of Environmental Protection was needed to address concerns about the potential negative effect of drones on the bats. We had to take a course with NJDEP and US Fish and Wildlife before participating in this use case. Bats wedge themselves deep within the cracks under the bridge. Our current drones could not get close due to proximity sensors, and illumination was insufficient. Cameras need to get relatively close to the bats and have good illumination to get quality photography. We have held two field trips to determine if the noise of the drone rotors would bother the bats and see what kind of photos we could get.  We discovered that the rotor noise was nothing compared to traffic noise. With the second STIC grant we hope to purchase equipment to improve illumination and image resolution, and allow us to get closer to the bats.

How many NJDOT staff from other divisions have been trained?

Ten staff members have been trained, and one of those has left. Only UAS program staff actively fly the missions, but trained staff members from other units have flown missions with UAS staff.  Although they do not fly frequently enough to be current and proficient, their knowledge of the UAS program helps their divisions with use case development – for example, in Traffic Management, CPM, and Multimodal. The intent of the STIC-funded training was to leverage our knowledge into the divisions. For example, when we confront a traffic issue for a project, I draw on the trained personnel in the traffic division to bring their colleagues into the conversation. They are our champions for the integration of UAS technology.

With our COAs, we are required to have night training.  With the regulations and procedures grant, we developed a NJDOT night-training video. We developed a PowerPoint training presentation with audio presented in a video format to be delivered to NJDOT UAS pilots. Not only initial training, but recurrent training is needed to renew certification and keep current. We have no active night missions with NJDOT at the moment but would like to do training missions in order to be prepared for an emergency response.

In our trainings and interactions with the divisions, we stress the importance of pre-flight preparation and coordination. A violation of regulations or inadequate coordination could set the program back years and other state DOT programs as well.

Have there been challenges to aspects of the program due to COVID-19?

Aeronautics is  currently understaffed with one of three inspector positions filled. I am the Program Manager for both Aeronautics and the UAS program so I am busy. The pandemic has affected our operations. In particular, coordination is more difficult without face to face meetings.

To what do you ascribe the success of the program?

For the I-495 project, live stream videos from drones were shared with traffic operations and command posts to assess traffic congestion during construction.

Lots of other state DOTs have UAS programs with more funding, resources, and staff but NJDOT’s program has been more successful because of our drive, determination, our champions, and relationships. The champions in NJDOT divisions have worked hard to successfully integrate UAS into their programs.

We have the confidence and experience to collaborate with federal agencies and other state agencies including FAA, airports, Secret Service, Homeland Security, NJ Department of Corrections, and state parks. During the Route 495 project, we had to deal with presidential temporary flight restrictions in Class B airspace. We had the confidence and the relationships with agencies, including Secret Service, to get through roadblocks. Homeland Security loaned us a staff person and a vehicle for several weeks to help support the Route 495 project. It is a collaborative effort; they bounce ideas off of us and we off of them.

Other state UAS programs have not pursued the relationships with these agencies or with divisions within their agencies.  We coordinate with NJDEP, for instance, for filming the NJDOT Winter Road-E-O which is held in a state park. We cannot take off and land in state parks but we can work with the state park to align our objectives with their requirements and regulations. Maritime missions in state parks are difficult to coordinate. However, with our contacts and our awareness of their concerns, we can streamline some of the approvals and fly the missions within the timelines we are given. The relationships are intangibles but a big part of the success of the NJDOT UAS program.

NJ STIC 1st Quarter 2021 Meeting

The NJ State Transportation Innovation Council (NJ STIC) 1st Quarter 2021 Meeting, held on March 29, 2021, focused on the advancement of the EDC-6 Innovative Initiatives during the two-year program time frame (January 2021-December 2023). The STIC Meeting Agenda had been distributed to the invitees prior to the meeting. Participants could use the chat feature to offer comments or ask questions of the speakers during the online meeting.

Amanda Gendek, Manager of the NJDOT Bureau of Research greeted the meeting participants, followed by Asst. Commissioner Michael Russo who provided the Welcome and Opening Remarks.

FHWA EDC-6 Innovation Baseline. Helene Roberts, Innovation Coordinator and Performance Manager for the FHWA NJ Office, noted that feedback from the STIC Caucus was helpful in establishing the baseline reports for the EDC-6 initiatives, and provided a brief update on the current and planned stage of deployment for each of NJDOT’s EDC-6 innovation initiatives over the two-year time frame.

Core Innovation Area (CIA) Updates. The meeting continued with presentations from Core Innovative Area (CIA) leaders who provided status updates, covering the EDC initiatives overseen by the Safety, Mobility and Operations, and Infrastructure Preservation CIA team. Amanda Gendek noted that the Organizational Improvement and Support CIA was formed recently to include the Strategic Workforce Development and Virtual Public Involvement initiatives. This CIA will be reporting out at the next STIC meeting.

STIC Incentive Grant Funding. Amanda Gendek reported on the status of the development of the NJ STIC Communications Plan which is a guide to encourage the exchange of ideas and promote innovation among STIC members and the broader transportation community. The Plan is nearing completion and will be available soon. Sal Cowan, Senior Director for Transportation Mobility at NJDOT, described the partnership with Waycare for the Enhanced Crowdsourcing for Operations in NJ pilot to improve traffic incident detection and roadway system monitoring.

EDC-6 Innovations Break-Out Sessions. The quarterly meeting offered an opportunity for STIC members to further consider how the EDC-6 initiatives can be advanced at the state and local level, and what coordinated efforts will be needed. Meeting participants were divided into break-out sessions to briefly discuss the current status of implementation for the EDC-6 initiatives and explore steps to be taken to advance these initiatives toward the anticipated implementation status at the end of the two years. Participants discussed their capacity to create a working group to continue discussion on these initiatives, how FHWA and NJDOT can work with local public agencies and other transportation partners to advance the initiatives, and whether participants are aware of innovations that could be shared at a future STIC meeting.

Plenary Session.  All participants reconvened and break-out group facilitators reported out on the discussions for each initiative.

Reminders and Updates.  Before closing the meeting, Amanda Gendek reminded meeting participants that information on NJ STIC is available on the NJDOT Tech Transfer website.  She let participants know that the 2021 Build A Better Mousetrap Competition is underway.  The BABM competition encourages state and local agencies to share successful examples of ideas that were translated into implementable solutions in transportation.  She also encouraged participants to subscribe to the NJDOT Tech Transfer News which is released quarterly to stay informed on other research and innovation topics.
