Developing Next Generation Traffic Incident Management in the Delaware Valley

Posted on

Traffic Incident Management (TIM) programs help first responders and traffic operators to better understand and coordinate roadway incidents. As part of the sixth round of the Federal Highway Administration’s (FHWA) Every Day Counts (EDC) initiative, the agency is promoting innovative practice in this area through NextGen TIM. These practices and procedures can advance safety, increase travel reliability, and improve agency operations by engaging with new technologies and trainings. For example, sensors and crowdsourced data can help traffic agencies better detect incidents and decrease response times. Drones, or Unmanned Aerial Systems (UAS) can help transportation agencies and first responders better understand the incident scene and speed the resumption of traffic flow. The NextGen TIM initiative is an effort to improve traffic incident management through technological innovation and standardized operating procedures. NextGen TIM technologies and practices are currently being used in the Delaware Valley to increase real-time situational awareness and ensure maximum safety at the scene of an incident.

Regional Integrated Multimodal Information Sharing (RIMIS)

Currently, transportation departments in the region use the TRANSCOM traffic monitoring platform to supervise incidents. The Delaware Valley Planning Commission (DVRPC)’s version of this platform is called RIMIS, or Regional Integrated Multimodal Information Sharing. Because DVRPC is a Metropolitan Planning Organization (MPO) that spans both sides of the Delaware River, its reach includes sections of New Jersey and Pennsylvania—broadly, the greater Philadelphia area. In this region, with overlapping municipal, state, and regional jurisdictions, communication and coordination could be difficult. According to Christopher King, Manager of DVRPC’s Office of Transportation Operations Management, before RIMIS, incident notifications were commonly communicated through phone calls.

Area transportation officials recognized the need for a coordinated platform where information could be shared back and forth. Instead of slow, one-to-one incident notifications, this new, decentralized platform would present a “big picture” perspective of a traffic incident’s impacts on the regional transportation network. The concept was to create a regional centralized information location for traffic operators and first responders to view the traffic status on area roads, and understand, quickly and reliably, where an incident has occurred. Local agencies could access the platform to better understand incident conditions.

RIMIS was first developed nearly 20 years ago, and has proved to be invaluable as a resource. Participants supply data, such as video feeds and traffic updates, which is then aggregated to update other members. These agencies include PennDOT, NJDOT, SEPTA, and NJ TRANSIT. Member agencies and municipalities, such as Bedminster Township, PA, can take advantage of the operations database, with live and historical traffic flow and incident data, a situational map which geographically represents traffic levels and incidents across the region, and a video wall of roads in the DVRPC area with live camera feeds.

As an example, Mr. King showed a municipal fire department participating in RIMIS, that, once alerted that a collision has occurred, can access the platform’s interactive map, live video feeds, and information on planned interruptions, to better understand the scene before arriving there. The RIMIS platform gives context to first responders on route to an incident, provides a broader view for traffic operations dispatchers managing a disruption, and also assists transportation planners looking for data on how to improve a high-collision roadway.

Interactive Detour Route Mapping (IDRuM)

Another TIM tool DVRPC provides is the Interactive Detour Route Mapping (IDRuM) feature, a web application that consolidates established Emergency Detour Routes as a resource for traffic operations personnel, first responders, and transportation planners and engineers.

If, for example, an incident has occurred on a certain segment of I-295 in Bucks County, then the Primary Detour Route would involve taking Taylorsville Road south and turning right on State Route 322 to rejoin the highway, while the Secondary Detour Route would take a similar maneuver going north. This information can be easily accessed in both interactive and PDF formats on the IDRuM mapping site.

DVRPC is currently working to integrate NJDOT’s designated Detour Routes into the GIS map for the area east of the Delaware. The data has been uploaded, but is still in beta testing.

NextGen TIM

Mr. King says that a chief focus of NextGen TIM is to expand services such as RIMIS and IDRuM to more localities and arterial routes, as well as to ensure that all first responders are trained in the most up-to-date TIM techniques, such as how to position their vehicles for maximum safety on an active roadway.

During the second round of the Every Day Counts Initiative (EDC-2, 2013-2014),  a TIM process and training program was established under the  SHRP2, or the second Strategic Highway Research Program. This laid the groundwork for the current TIM training and organizational infrastructure, which is NJTIM in the Garden State. This consortium, spearheaded by NJDOT, provides resources and trainings to teach best practices to first responders across the state. NJDOT and the New Jersey State Police (NJSP) partner together to promote trainings and coordinate highway emergency response.

VW Mitigation and Emissions Offset Funds Fuel NJ’s Clean Transportation Transformation

In February of 2021, Governor Phil Murphy announced a historic $100 million investment in clean energy transportation vehicles and infrastructure, building on work laid out in the 2020 Energy Master Plan, which calls for a transition to 100 percent clean energy by 2050. In 2019, the State emitted 97 million metric tons (MMT) of carbon dioxide (CO2); with the implementation of the Energy Master Plan, annual emissions are projected to be dramatically reduced to 24.1 MMT of CO2. Several NJ State agencies are working to lay the foundation for this monumental transition. The $100 million commitment is only one aspect of a much larger, inter-agency undertaking.

The Energy Master Plan provided a blueprint for New Jersey’s greenhouse gas reduction goals, and the 2020 New Jersey Senate Bill 2252 (S2252), commonly referred to as the electric vehicle law, is the legislative impetus for such work. The New Jersey Department of Environmental Protection (NJDEP), the New Jersey Economic Development Agency (NJEDA), the New Jersey Department of Transportation (NJDOT), and NJ TRANSIT, among others, are now collaborating to achieve the transformation of the transportation sector, responsible for the largest share of the State’s net greenhouse gas emissions, to 100 percent carbon neutral.

Zero Emissions Vehicles (ZEVs) from Volkswagen Funds

The clean energy initiative is funded, in part, through a legal settlement negotiated between Volkswagen and the United States Environmental Protection Agency (USEPA) and the California Air Resources Board (CARB), after a court determined that the automaker had installed defeat devices that hid emissions of nitrogen (NOx) in certain vehicles models. From the resulting $3 billion settlement, New Jersey was allocated $72.2 million, which is now being administered by NJDEP for clean energy transportation projects.

The first and second rounds of New Jersey’s Volkswagen Mitigation Trust proceeds were awarded to select applicants for the purchase of ZEVs. For example, $1.9 million was given to a company in Trenton for five new electric school buses, and Jersey City received $2.4 million for five new electric garbage trucks. Red Hook Terminals LLC of Port Newark (pictured at right) recently received sufficient funding to purchase ten electric yard tractors.

Without sufficient charging infrastructure, the envisioned shift to EVs will prove impossible to achieve. One oft-cited reason hindering EV adoption is “range anxiety,” a fear of not being able to refuel for lack of nearby facilities. Currently, 95 percent of state residents live within 25 minutes of a DC Fast Charger, a distance that will only decrease as new chargers are built. Stations throughout the State can be located using NJDEP’s Public Electric Vehicle Charging Locator.

For Phase 1 of the Volkswagen Mitigation Fund disbursal, NJDEP allocated $3.2 million to pay for public fast chargers. In 2019, through the It Pay$ to Plug In program, VW funds have financed 827 new charging outlets, ranging from the City of Cape May, to Rutgers—New Brunswick, to the Village of Ridgewood.

An important source of revenue for supporting Governor Murphy’s $100 million pledge is the Regional Greenhouse Gas Initiative (RGGI). RGGI is a multistate partnership that has set a regional cap on carbon dioxide emissions. Fossil-fueled power plants exceeding the limit must purchase extra capacity at an RGGI auction. In the first quarter of 2021, New Jersey received $27.1 million that will be invested to fight climate change according to a Strategic Funding Plan. The New Jersey RGGI Climate Investments Dashboard provides up-to-date, visual reports of progress on RGGI grants across the State. The initiative has awarded $22.2 million thus far to several municipalities, including for the purchase of two electric garbage trucks for the City of Trenton, and two electric shuttle buses for West New York.

The RGGI purchases coincide with Phase 2 of NJDEP’s Volkswagen settlement disbursal, announced in February, 2021. A further $31.7 million of funding for ZEVs from the settlement will be distributed across the state. As Passaic County receives RGGI funds for an electric shuttle bus, the City of Paterson has been allocated VW money for two electric garbage trucks. With VW funds and RGII auction proceeds, the City of Elizabeth School District purchased seven electric schoolbuses. Gradually, municipalities and companies across the state are beginning to grow their ZEV fleets.

To complement these 2021 ZEV additions, NJDEP has proposed spending an additional $5.4 million of Volkswagen funds for charging grants. For example, the agency selected an ACME grocery store in Woodbury, a Shell station in Wayne, and a hotel in Fort Lee, among others, for DC Fast Charger grants. The DC Chargers are being prioritized in this round because of their high efficiency: a twenty-minute charge can add 60 or 80 miles of driving range.

Emissions Mitigation for Heavy Transportation

In July, 2020, New Jersey and fourteen other states and the District of Columbia signed a Memorandum of Understanding (MOU) committing to collaborate on policies to convert medium and heavy-duty vehicle fleets, such as school buses and freight trucks, into ZEVS The MOU sets a goal of 30 percent electric share heavy and medium-duty vehicles sold in 2030, with a 100 percent share by 2050. The regional approach reflects an acknowledgement that transportation emissions are an interstate issue, and that interstate collaboration is necessary to meet such goals.

Image of a slide reading Proposed ZEV Sales Requirements, detailing how manufacturers in NJ will have to provide credits each year starting in 2024 to offset the emissions cost of the vehicles they are selling. By 2034, for example, they will have to sell (or purchase credits for) 50% of their vehicles as clean energy vehicles.

To begin instituting this shift, NJDEP has started the rulemaking process for N.J.A.C. 7:27-31 and 33, two proposed regulations that would institute a credit/deficit program for manufacturers of trucks of over 8,500 pounds. Beginning in 2025, sellers of medium and heavy-duty vehicles would be required to generate or purchase credits to offset deficits from the sale of greenhouse gas-emitting vehicles. This offset could be accomplished by increasing sales of ZEVs, or by purchasing credits from another manufacturer. Deficits would increase every year through 2035, resulting in an increase in the number of commercial ZEVs sold in the state. This is modeled after the Advanced Clean Trucks (ACT) rule that California implemented in 2019.

For public transit, bus fleets must be converted as well. The state’s EV law, S2252, requires that NJ TRANSIT transition its new bus procurements to all-electric. New bus purchases must be 50 percent electric by the end of 2026, and 100 percent zero-emissions by the end of 2032. NJ TRANSIT, which received funds for eight new electric buses in Camden from VW Phase 1, will start testing these vehicles in service in the fall of 2021. One issue affecting the conversion is range; on certain routes, particularly in South Jersey, the required driving distance exceeds single charging capacity. NJ TRANSIT is currently exploring solutions such as building new chargers and making changes to operating routes.

Conclusion

Though $100 million is a significant investment, more resources will be needed to promote the transition from carbon-emitting vehicles. Further investment, as well as interagency and regional cooperation will be crucial to meet the Energy Master Plan’s goal of 330,000 ZEVs on New Jersey Roads by 2025.

NJDOT is working to support the efforts of agency partners to achieve the goals set out by the Energy Master Plan and mandated by the electric vehicle law. NJDOT has continued to invest in alternative mobility, increasing traffic efficiency, and the conversion of its fleet to ZEVs.  In a recent NJDOT newsletter, the Commissioner Diane Gutierrez-Scaccetti noted that the agency has worked with a team from Princeton University to determine an electric charging infrastructure implementation plan, the first step of which will be installation of equipment at the Ewing, New Jersey headquarters.

This infrastructure will be important not just for NJDOT but for the statewide fleet, which, as it transitions to ZEVs, needs centralized charging infrastructure. By law, the statewide fleet must be 25 percent electric by 2025, and 100 percent electric in 2035. NJDOT has already ordered 49 hybrid vehicles, progressing toward the department goal of 88 alternative fuel vehicles in service in the next three years.

Success will require not only committed public policy, but overwhelming public support to make use of the budding charging network, expanded subsidies, and soon-to-be converted fleets.

FHWA Issues EDC-5 Final Report and EDC-6 Baseline Report

Posted on

The FHWA has issued a Final Report for Round 5 of the Every Day Counts Initiative (EDC-5), and a Baseline Report for EDC-6. The reports demonstrate completed and preliminary progress on implementation of selected innovations, such as Crowdsourcing for Advancing Operations and e-Ticketing.

Since the advent of the program in 2009, FHWA has worked to standardize innovation as an industry practice. For EDC-5, which took place from 2019-2020, FHWA reports that state agencies accomplished 98 percent of their implementation goals—the highest success rate since EDC began. The vast majority of innovative ideas have been demonstrated, assessed (in preparation for deployment), or institutionalized by the state agency.

NJDOT is committed to supporting this initiative, which is administered on a state-by-state basis. The New Jersey Strategic Innovation Council (NJSTIC), is comprised of various stakeholders, including representatives from NJDOT, universities, municipalities, Metropolitan Planning Organizations, and counties. NJ STIC meets quarterly to discuss new innovations and progress on initiatives. More information about NJ STIC can be found here.

The second EDC-5 Progress Report summarizes the deployment progress of the 10 innovations in the fifth round of the the Federal Highway Administration’s Every Day Counts program for July through December, 2019. The EDC program coordinates the deployment of new strategies and technologies within State Departments of Transportation. These strategies help transportation stakeholders to shorten the project delivery process, enhance roadway safety, reduce traffic congestion, and integrate automation to better serve the nation.

The national report analyzes each state’s implementation stages for the 10 innovations using charts and maps. The report also presents the number of states that have demonstrated, assessed, or institutionalized innovations, and presents goals for how many states should reach these stages by December 2020. New Jersey Department of Transportation has fully institutionalized Crowdsourcing for Operations, Project Bundling, and Unmanned Aerial Systems. The agency has reached the assessment stage for Safe Transportation for Every Pedestrian, and the demonstration (testing and piloting) stage for Advanced Geotechnical Exploration Methods and Collaborative Hydraulics. Two other innovations are in the development phase.

FHWA compiles a progress report every six months regarding the state of practice for the current round of EDC initiatives. An online version of the EDC-5 Progress Report can be found here.
