Q&A: What’s EPIC2 about Internally Cured Concrete?

Posted on

Enhancing Performance with Internally Cured Concrete (EPIC2) is a model innovation in the latest round of the FHWA’s Every Day Counts Program (EDC-7). EPIC2 is recognized as an innovative new technique that can be used to extend the life of concrete bridges and roads. Internal curing increases concrete’s resistance to early cracking, allowing the production of higher-performance concretes that may last more than 75 years.

This Q&A article has been prepared following an interview and follow-up correspondence with Samer Rabie and Jess Mendenhall of the New Jersey Department of Transportation. The Q&A interview has been condensed and edited for clarity.

Q. What is Internally Cured Concrete, and how does it differ from traditional concrete?

A common issue with high performance concrete (HPC) bridge decks is that soon after the curing is done, they develop fine shrinkage cracks spread throughout the deck. Even this fine cracking can reduce the service life. In the past, we have used crack sealing materials as a mitigation effort, but when we learned about internally cured concrete, we shifted our focus to see if we could adopt it in New Jersey.

Figure 1. Illustrating the difference between conventional and internal curing

Autogenous or chemical shrinkage is specific to HPC concrete, where the w/c ratio is less than 0.42. It is due to self-desiccation, which is water consumed by the cementitious materials after setting, and that is one where internal curing can help.

There are multiple methods to implement internal curing. The method that we are considering involves  modifying a conventional concrete mixture to an internally cured concrete mixture by replacing a portion of the fine aggregate (sand) with lightweight fine aggregate. This lightweight fine aggregate (LWFA) is saturated with internal curing water, typically estimated at 7lbs of water for every 100lbs of cementitious materials used in the mixture. Next, the amount of LWA required for this amount of internal curing water is determined based on the mass of the internal curing water and the absorption of the LWFA. Once the total volume and mass of lightweight aggregate are determined, the volume (and mass) of the fine lightweight aggregate are adjusted so that the volume of LWFA and fine aggregate in the internally cured mixture is equal to the volume of the fine aggregate in the original mixture.

The LWFA will provide internal curing water within the concrete mix during curing, and prevent a condition that occurs in low W/CM ratio systems where the capillary water within the concrete matrix pores will be consumed without complete cement hydration, which can lead to cracking of the concrete matrix.

Q. How does Internally Cured Concrete improve performance?

Internal curing improves the performance of concrete by increasing the reaction of the cementitious materials and reducing internal stresses that typically develop in high-cementitious content mixtures if insufficient internal curing water is present. However, in addition to conventional curing which supplies water from the surface of concrete, internal curing provides curing water from the aggregates within the concrete. This provides a source of moisture from inside the concrete mixture, improving its resistance to cracking and overall durability.

Q. Are there any limitations on the use of internally cured concrete?

Internal curing is extremely versatile and  can generally be used anywhere traditional concrete is used. Most of the process is the same, and aggregates can be pre-saturated as needed. It follows the norms of industrial concrete production, making it accessible to any producer already familiar with the state of practice. Most of the implementation process is similar to conventional concrete.

Q. What New Jersey sites were picked for use in internally cured concrete, and why?

We started with a list of all of our bridge projects, specifically projects that needed deck replacement and superstructure replacement. We then further targeted projects that allowed us to focus on implementation and quick delivery time rather than constructability and other additional challenges. We looked at projects with straightforward staging and geometry and prioritized projects with twin bridges (for example, northbound and southbound). This would allow us to do one bridge with traditional HPC and the other with internally cured HPC, providing us with an excellent controlled opportunity to study and compare the results.

Various sites have been screened throughout the state. Currently, eight bridges are under consideration, with a project scope of work of deck and superstructure replacement. The rationale included the project scope of work, CIP deck slabs, project schedule, staging constraints, and avoiding heavily skewed bridges.

Q. Have any life cycle cost analyses been performed?

We have not prepared one ourselves, but we do plan on doing so in the future. First, we will need to get these projects out to construction and get actual cost data. We’re expecting higher upfront costs, but if cracking is reduced then the life cycle costs and future maintenance and reconstruction needs can be significantly reduced.

Q. In what ways do you think people can be better educated on the implementation of EPIC2?

We have presented to many of our stakeholders in our capital program to discuss the topic, and now that it is an EDC initiative,  decision makers are acknowledging its value. The Federal Highway Administration is also planning on conducting workshops and peer exchanges between contractors, concrete suppliers, and other agencies like New York State DOT, which have already done this. All of these are extremely valuable.

We first heard about internally cured concrete during a peer exchange in 2021 with the New York State DOT. It was under the banner of EDC-6, and they took us out on several bridges where we noted that they have significantly reduced the typical shrinkage cracking that is common with High Performance Concrete. So that was an eye opening experience for us, and I know it would be valuable to others. The fact that it is now its own initiative in EDC-7 helps facilitate implementation.

Q. Is special training needed for contractors to work with internally cured concrete?

From our research and experience with other agencies, the finishing should not be significantly different from conventional HPC. The process at that point will be almost identical to placing traditional concrete, so there won’t be any learning curve or time spent on getting workers to learn how to deal with a new material. In fact, most contractors say that the mixture is easier to work due to improved pumpability as the material is quite smooth. I think the crucial step will be to coordinate with concrete production plants that are creating the mixes.

Figure 3. States that have implemented EPIC2 on their roads or bridges

Q. Where else has internally cured concrete been implemented?

So far it has been used in bridge decks in many states, including New York, Ohio, and North Carolina, among others. It has also been used in pavement and pavements in Kansas, Texas and Michigan.

Q. What is the future of internally cured concrete in New Jersey?

We hope these projects will be successful, and that our current crop of projects will result in some valuable lessons learned. In the long term, I believe the goal would be that all of the bridge decks would use an internally cured mixture. I can also see this being used for patching and deck repair jobs. But ultimately, the goal would be for this to become the new standard for bridge decks across the state.

Did You Know? Research on ALICE and Mobility of Low-Income Households

Posted on

At the 2023 NJDOT Research Showcase, New Jersey Transportation Commissioner Diane Gutierrez-Scaccetti “appealed to attendees to advance community-centered transportation and to commit to considering the needs of ALICE (Asset Limited, Income Constrained, Employed) persons when devising research questions and in carrying out their day-to-day activities with the goal of planning, building and maintaining a more safe, equitable and sustainable transportation system.” Gutierrez-Scaccetti has repeatedly said that she “drives with ALICE” in mind, but that ALICE would rather drive by herself. On Jan. 30, 2023, Gutierrez-Scaccetti spoke at the National ALICE Summit on Navigating the ALICE Highway: A Multistate Transportation System by 2030.

In recognition of the Commissioner’s emphasis on getting to better know who ALICE is, the NJDOT Research Library has done a quick research of resources related to the mobility of low-income households and the ALICE project at The United Way. These are included below:

United Way of Northern New Jersey operates the website United for ALICE, which maintains research pages for “partner states” (28 states, including New Jersey, plus the District of Columbia). United Way of Northern New Jersey (then known as United Way of Morris County) released its first ALICE report in 2009.

United Way prepares state fact sheets that compare the ALICE Essentials Index (AEI) to the Consumer Price Index (CPI) over time.

The October 2023 NCHRP Research Results Digest, Collective and Individual Actions to Envision and Realize the Next Era of America’s Transportation Infrastructure: Phase 1, includes this background on ALICE households: “Economic growth and prosperity have not been spread evenly across the United States. About 13 percent of households earn incomes below the poverty line and an additional 29 percent are considered to be asset-limited, income-constrained, and employed (ALICE)…. The average household spends 16 percent of total expenditures on transportation—the second biggest cost after housing…. Significant numbers of Americans have limited access to health care, education, fresh food, or high-speed Internet.”

In 2018, New Jersey Governor Phil Murphy cited “more than one million [ALICE] families” in New Jersey as the impetus to raise the state’s minimum wage to $15 per hour. In 2024, New Jersey’s minimum wage will surpass $15 for the first time.

A November 2023 article from the journal Social Science & Medicine laments the fact that public health studies have not used ALICE data.

The Mackinac Center for Public Policy takes an opposite tack in its criticism. It issued a 2021 report, An Assessment of ALICE: A Misleading Measure of Poverty. “Unfortunately, United Way’s research on this issue is methodologically flawed, misleading and does not help inform the public or policymakers about how to help these households,” the authors write. The Mackinac Center for Public Policy describes itself as “a nonprofit research and educational institute that advances the principles of free markets and limited government.”

United for ALICE states that it provides “unbiased data that is replicable, easily updated on a regular basis, and sensitive to local context,” and that its published measures provide a better picture of “the number of households that are struggling in each county in a state,” compared with the Federal Poverty Level. United for ALICE’s most recent research methodology report was published in April 2023.

Transportation research on low-income individuals can be found via the TRID and ROSA-P databases.

The following are some relevant articles on the topic, curated by the NJDOT Research Library:

Current research projects into the topic of serving low-income populations include these:

NJDOT’s Research Showcase Recognized as Best Virtual Event by AASHTO Communications Committee

Posted on
The AASHTO 2023 Best Virtual Event Award recognizes a special event that is held virtually or that includes a virtual component.

AASHTO’s Committee on Transportation Communications – known as TransComm – sponsors an annual skills awards competition to promote the sharing of best practices and to recognize outstanding communications efforts. In October 2023, NJDOT Bureau of Research representatives Amanda Gendek and Pragna Shah accepted the 2023 AASHTO TransComm Skills Award in the Virtual Events Category for NJDOT’s 24th Annual Research Showcase. 

The NJDOT’s Bureau of Research Annual Research Showcase has been held since 1999 and provides an opportunity for the state’s transportation community to experience the broad scope of research initiatives and technology transfer activities conducted by their university and consultant partners. In addition to convening transportation professionals and researchers, the Showcase helps to emphasize NJDOT goals and objectives, share knowledge, and recognize the outstanding and inspiring research being done in the state.

The threat of COVID-19 transmission during the pandemic led to the Research Showcase being held fully online in 2020 and 2021. These fully virtual events resulted in a much larger audience, and even attracted attendees from other state Departments of Transportation. In 2022, as in-person events returned, the NJDOT Bureau of Research sought to find an approach that would maintain that larger audience base.

The 24th Annual Research Showcase, held October 26, 2022, was the first “hybrid” Research Showcase held by NJDOT and allowed individuals to attend the event online, while also allowing those able to gather, network and celebrate in person. Convening in a hybrid format required some additional coordination with the event planning team from Rutgers and Civic Eye Collaborative, a media consultant firm to live-stream the day’s proceedings. In total, 117 virtual participants and 190 in-person participants attended the day-long event.

Whether attending “in-person” or “virtually,” the audience heard from the keynote speaker and panelists on the major theme of the event “Advancing Equity in Transportation.” 

The Showcase theme, “Advancing Equity in Transportation” served as the organizing framework for the keynote speaker and panelists during the morning plenary session. The keynote speaker, Keith Benjamin, Associate Administrator for Highway Policy and External Affairs at the FHWA, spoke about the USDOT’s efforts to advance equity, highlighting the Infrastructure Investment and Jobs Act and the Inflation Reduction Act and various funding and program initiatives to address equity in transportation planning, project development, and other activities, among other topics. A panel session then explored the perspectives of representatives from NJDOT, county government, and transportation management associations (TMAs) who shared examples of the equity initiatives underway in their organizations. Questions and discussion invited panels to further reflect on the challenges and opportunities for advancing equity in transportation in New Jersey.  

The Showcase included afternoon breakout sessions featuring research presentations that continued to address the equity theme as well as other mobility, infrastructure, safety topics in transportation being performed by research faculty, staff, and students and NJ agencies. Several awards were also presented in recognition of research accomplishments and implemented innovations. For a full description of the 24th Annual Research Showcase event, see this recap here.

The 24th Annual Research showcase was recognized with the AASHTO Award for its efforts to enhance accessibility through the virtual platform. In addition to live-streaming the plenary and breakout sessions, the video recordings of the event were posted on NJDOT’s Tech Transfer Video Library and all those who registered were notified of its availability — whether attending in-person or online. Subsequent direct email communications and social media posts have further broadened the audience of potential viewers. To watch recordings from this, and other Research Showcase events, visit the NJDOT Tech Transfer Video Library.

The theme of the 24th Annual Research Showcase was selected in recognition of the significant Federal and state efforts underway to advance equity; Executive Order 13985 established a “whole government approach” to advancing equity and opportunity at the Federal level (left). Dr. Shawn Wilson, then-Secretary of Transportation in Louisiana, headlined a roundtable discussion, “State DOTs: Creating Pathways to Equity” at the Transportation Research Board’s 2022 Annual Meeting (right).

Research to Implementation: The Use of Porous Concrete in Sidewalks

Posted on

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.

Pervious (or porous) concrete has been gaining popularity as a potential solution to reduce the amount of impermeable surfaces associated with sidewalks, reduce puddling, and potentially slow storm water surface runoff. As important as these benefits are to surface runoff mitigation, concerns exist as to the ability of pervious concrete to provide sufficient structural support and longevity for the expected service life of the sidewalks as well as its life cycle costs. The composition of pervious concrete can limit its mechanical strength and present challenges in its maintenance to achieve the expected service life.

With support from NJDOT’s Bureau of Research, researchers have looked at the benefits and challenges to utilizing porous concrete for sidewalks, and conducted a follow-up demonstration project. For more information about this research and the demonstration project, see: The Use of Porous Concrete for Sidewalks and Implementation of Porous Concrete for Sidewalks in New Jersey.

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

Recap: 25th Annual NJDOT Research Showcase

Posted on

The 25th Annual NJDOT Research Showcase provided an opportunity for the New Jersey transportation community to learn about the broad scope of academic research initiatives underway and share technology transfer activities being conducted by institutions of higher education partners and their associates. The annual event serves as a showcase to highlight the benefits of transportation research, including NJDOT’s own program. This event was an in-person event with a livestreaming option with sessions held from 9:00am-2:45pm on October 25, 2023.

This year’s Showcase theme, “Commitment to Safety,” served as the organizing framework for the speakers and panelists during the morning plenary session. Throughout the day the Research Showcase featured presentations on infrastructure, safety, mobility, and equity topics being performed by research faculty, staff, students, and NJ agencies. Several awards were presented in recognition of research and implemented innovations.

The Research Showcase Program Agenda provides more information on the day’s proceedings, including presented topics and invited speakers. Recordings of the plenary and breakout sessions, and the presentations and posters shared during the event can be found below.

MORNING

WELCOMING AND INTRODUCTORY REMARKS

David Maruca, Program Development Administrator, Rutgers Center for Advanced Infrastructure and Transportation, served as the moderator for the morning session, offering some housekeeping remarks and walked through the morning’s agenda.

Morning Plenary and Keynote

Andrew Swords, Director, New Jersey Department of Transportation Division of Statewide Planning, welcomed attendees to the 25th Annual NJDOT Research Showcase, explaining the purpose and theme of the event, “Commitment to Safety,” and acknowledging several parties, including NJDOT Bureau of Research staff, Rutgers-CAIT, and the leadership of NJDOT and FHWA for their planning and participation in the day’s event along with the research partners whose work was being showcased.

Diane Gutierrez-Scaccetti, Commissioner, New Jersey Department of Transportation, thanked several partners for their involvement in the event and reflected on the history of the Research Showcase Event on the occasion of the 25th Anniversary. In framing the day’s activities, Commissioner Gutierrez-Scaccetti recognized the event’s “Commitment to Safety” theme and the foundational importance of transportation for affecting positive change, improving the quality of life, and the shape of New Jersey’s transportation system. In her remarks, she appealed to attendees to advance community-centered transportation and to commit to considering the needs of ALICE (Asset Limited, Income Constrained, Employed) persons when devising research questions and in carrying out their day-to-day activities with the goal of planning, building and maintaining a more safe, equitable and sustainable transportation system.

Robert Clark, Division Administrator, Federal Highway Administration New Jersey Division acknowledged the importance of the NJDOT Research Showcase’s “Commitment to Safety” theme. He described several policy and research commitments at U.S. DOT, FHWA Turner-Fairbanks Research Center and the Volpe Center that are intended to “double-down” on improving safety, reducing fatalities and strengthening the culture of safety in transportation. In closing out, Mr. Clark shared the USDOT Commissioner’s message that roadway deaths is a crisis that is urgent, unacceptable and preventable; those in attendance should see that their work and research into safety can prove that roadway fatalities need not be inevitable.

KEYNOTE ADDRESS

Dr. Allison E. Curry, PhD, MPH, Associate Professor of Pediatrics, Children’s Hospital of Philadelphia delivered the keynote address on the New Jersey Safety and Health Outcomes (NJ-SHO) Data Warehouse. In organizing her talk, she explained the vision behind the development of the data warehouse over the last 15 years, the data sources that have been employed, its innovative features that can support meaningful research, and her vision for future research and collaborations drawing upon the data warehouse platform.

Dr. Curry described how crash data can be linked to other data sets to extend the period of study about crashes. She explained the data warehouse has been built through an array of administrative data partnerships with NJ agencies (e.g, public health, hospital, motor vehicle, police, medicare and medicaid, etc.) that have been linked alongside rich community-level indicators available at the census tract level to create a robust data tool for traffic safety research.

Her talk highlighted some of the limitations of crash reports that explain the need for data integration with other administrative record sources. She emphasized the longitudinal features of the data warehouse and explained how its linkages to health and motor vehicle records makes it possible to study specific populations segments — for example, teens on the autism spectrum. In her example, she described her research demonstrating how the data sets could be used to investigate the percentage of teens with autism who acquired driver licenses to increase their travel independence. She also could compare whether crash rates were comparable between this group and other teens in their age cohort at 12 months and 48 months from receipt of a license.

Dr. Curry also highlighted data limitations on reporting of race and ethnicity on NJ crash and licensing data and how other data sources (e.g., hospital discharge, electronic health records, birth and death data, etc. ) can be used to look at race and ethnic differences in non-fatal crash outcomes.  In doing so, she highlighted how a probability-based algorithm, Bayesian Surname Geocoding (Sartin 2021), developed by the RAND Corporation, has been applied to estimate the race and ethnicity of driver licenses and address a source of race and ethnic bias in hospital record reporting due to varying levels of hospital usage.

Dr. Curry touched upon several of NJ SHO’s innovative features that can enable research.  Among other points, she contrasted the “urban planning lens” which considers the place in which an accident occurred with the “public health lens” which seeks information about persons who are crash victims and where they live.

She also offered illustrative examples of how the NJ-SHO can be linked to vehicles to examine types of crashes, vehicle types and the injuries incurred which can reveal differences among more vulnerable populations (e.g, youth, elderly, poor) from other populations.

Dr. Curry closed her talk with a sneak preview of a new interactive data dashboard, NJ-SHO Center for Integrated Data, currently in development in association with the NJ Division of Traffic and Highway Safety. She noted how the dashboard tool will help practitioners efficiently use available data sets in ways that will mirror the metrics of the NJ Strategic Highway Safety Plan with a focus on persons as well as community resilience and social vulnerability equity-oriented measures.

Dr. Curry responded to questions in a Q&A session that followed her keynote remarks.

MORNING SESSION PANEL DISCUSSION

An interactive panel discussion, “How is New Jersey Department of Transportation Addressing Safety?” followed the keynote session with state NJDOT staff representatives who presented examples of the safety initiatives underway at NJDOT and reflected on persistent challenges and opportunities for addressing transportation safety in New Jersey.

AWARDS

The program continued as Dr. Giri Venkiteela Research Scientist, Bureau of Research, New Jersey Department of Transportation announced several awards given in recognition of research, innovation and implementation efforts. Below is a listing of the award winners presented at this year’s showcase:

  • 2023 Outstanding University Student in Transportation Research Award – Alissa Persad, Rutgers University, Ms. Persad was being recognized in part for her valued contributions to the Innovative Materials for Quick Patching and Repair of Concrete project.
  • 2023 NJDOT Research Implementation Award – Dr. Hao Wang, Rutgers University Energy Harvesting on New Jersey Roadways. This project identified potential energy harvesting technology for applications on roadways and bridges and conducted feasibility analysis and performance evaluation of the selected technologies for large-scale and micro-scale energy generation.
  • 2023 Best Poster Award – Alyssa Yvette Sunga, Rowan University, Properties of Cementitious Materials with Reclaimed Cement. This poster described research activities that obtained recycled concrete; determined the chemical composition of reclaimed cement; partially replaced ordinary Portland cement with reclaimed cement in cement paste and mortar; and determined the fresh and hardened properties of cement paste and mortar through tests measuring flowability, initial setting time, heat of hydration, and compressive strength.
  • 2023 Research Champion Excellence Award – Thomas Bushar, New Jersey Department of Transportation, Materials. This award recognizes Mr. Busher’s dedication while serving as a Technical Advisory Panel member for The Evaluation of Different Paint Systems for Over-Coating Existing Structural Steel project. The award notes that his commitment greatly contributed to the success and implementation of this research project.
  • 2023 NJDOT Build a Better Mousetrap Award – Gerald Oliveto, P.E. New Jersey Department of Transportation, Moveable Bridge Unit. The “Route 71 Over Shark River Road Diet” is a road diet project that preserves an old historic drawbridge while improving safety and saving money.  When the Route 71 Drawbridge over Shark River between Belmar and Avon-by-the-Sea in Monmouth County suffered a mechanical failure in September 2021, engineers worked quickly to design and implement a solution that would both preserve the drawbridge and keep it in safe operation. The traffic load needed to be redistributed and balanced properly across the span to keep the bridge opened. NJDOT implemented a road diet across the bridge, which allowed the Department to address several safety issues. Traffic over the bridge was reduced from one northbound lane and two southbound lanes to one lane in each direction. Signal timings were adjusted, safety improvements at surrounding intersections were installed, and highway signage was enhanced. In addition, bike lanes that had previously ended abruptly were carried across the drawbridge utilizing an innovative bicycle-safe grid, a first-of-its-kind achievement in New Jersey. Through this $150,000 project completed in May 2022, the Route 71 over Shark River Road Diet project improved traffic flow, increased safety, and reduced congestion in a busy tourist area.

Research Underway to Address Travel Needs of Cognitively Divergent Individuals in Complete Streets Plans

Posted on

The Complete Streets planning approach pushes for a future in which people of all ages and abilities can safely travel. Recently signed NJ legislation takes an important step toward this vision by ensuring that the travel needs of cognitively divergent individuals are addressed in Complete Streets Plans.

In January 2023, Governor Phil Murphy signed S-147 into law, directing the New Jersey Department of Transportation (NJDOT) to update its Complete Streets policy to consider and implement design elements and infrastructure projects that promote the ability of persons diagnosed with autism spectrum disorder (ASD) and persons with intellectual and developmental disabilities (IDDs) to travel independently.

This requirement follows important research conducted by Rutgers CAIT and VTC and funded by NJDOT, in which the travel behavior of over 700 adults with autism spectrum disorder (ASD) was studied. The research concluded that individuals with ASD, seeking to travel independently, experience extraordinary transportation barriers that are complicated by the state’s auto-oriented street design and land uses. With fewer such persons driving cars, an improved network of walking and biking infrastructure opens a world of opportunities for engagement in civic life and to reaching essential destinations via public transportation.

The Complete Streets Summit event will include a session on efforts underway to revise policies to promote travel independence for ASD with IDD persons.

NJDOT has undertaken a project that seeks to address how to accommodate the travel needs of people with ASD and/or IDDs through policy and design. The Department’s Bureau of Safety, Bicycle and Pedestrian Programs has engaged the Rutgers-Voorhees Transportation Center, NV5, Toole Design Group and a working group of NJDOT planners and engineers to assist with addressing the travel needs of cognitively divergent persons – and with meeting the requirements of the legislation.

The research team is developing a primer on Complete Streets and neurodivergence and will use the information gathered to help NJDOT develop universal design guidelines that will ensure the Department’s Complete Streets policy considers the needs of those with ASD and IDDs. The team will be sharing more information at the upcoming 2023 New Jersey Complete Streets Summit on November 1st. Not yet registered? Register Here.

More information on the past and ongoing research underway and how cognitive functioning can differ among members of ASD and IDD populations is summarized in this short article, Complete Streets for Individuals with Autism Spectrum Disorder (ASD) and Intellectual and Developmental Disabilities (IDDs), on the NJ Bicycle and Pedestrian Resource Center website.

NJDOT Traffic Incident Management Training Course – Now Available Online as Self-Guided Course

Posted on

The New Jersey Department of Transportation’s Traffic Incident Management (NJTIM) training is now available as an online, self-guided course. Bringing first responder training program to an online training platform should make it easier for even more emergency and incident response personnel to access a life-saving training. The new online course can be accessed through the NJTIM website.

The TIM training program focuses on a response effort that protects motorists and first responders during a roadside emergency, while minimizing impact on traffic flow. Since its inception in 2009, NJDOT and its partner agencies have trained more than 24,000 emergency and incident response personnel, including police, firefighters, EMS personnel, DOT crews, towing/recovery companies and other responders.

Training efforts, like these, are crucial in coordinating response efforts that keep all first responders and transportation professionals safe.

The new online training course can be found at NJ TIM Website: njtim.org

Providing easier access to TIM training for busy first responders and transportation professionals should prove more cost effective than traditional, in-person meetings for organizations with limited budgets. The online training program is asynchronous, offering greater flexibility in taking the training for personnel whose work schedules may not align with in-person training dates.

Online programs can also be easily updated and revised, ensuring that participants receive the most current and relevant information.

The online training is designed to engage training participants with videos, simulations, knowledge checks, and interactive scenarios that mimic real-world situations. The online TIM training utilizes assessments and certifications to evaluate the trainees’ understanding of the material and practice decision-making in high-stress scenarios without real world consequences.

The online TIM training program seeks to improve safely and coordination in responding to incidents on New Jersey’s roadways. The target audience for this training is county and municipal law enforcement and emergency personnel, including volunteer firefighters and EMTs.

FHWA’s Every Day Counts Program has recognized the importance of TIM as model safety and mobility innovation. In Round 6, Next-Generation TIM: Integrating Technology, Data, and Training, the importance of training of local agencies was encouraged.

The FHWA’s Talking TIM webinar series provides best practices, new technological innovations, and successful implementations. The webinar series provides a forum where TIM champions with any level of experience can exchange information about current practices, programs, and technologies.

More information on the rationale and benefits of the new course can be found in the video and the NJDOT press release.
