Innovation Spotlight: Testing and Deploying ITS Solutions for Safer Mobility and Operations

NJDOT’s Transportation Mobility unit is working on several initiatives related to FHWA Every Day Counts innovative initiatives, including: Crowdsourcing for Advancing Operations (EDC-4, EDC-6), Next Generation Traffic Incident Management (EDC-4, EDC-6), and Weather Responsive Management Strategies (EDC-4, EDC-5).  The unit has been creatively deploying STIC Incentive Grants and Accelerated Innovation Deployment (AID) grants to pilot test and evaluate innovations in recent years. We spoke with Sue Catlett, Project Manager in the Mobility Research Group, to provide updates on this work and discuss the coordination needed between agencies, organizations, and industry to make progress on these initiatives, and the barriers to deployment.

The Waycare crowdsourcing platform will feed information to NJDOT’s traffic operations centers to help resolve traffic issues and improve safety.

Crowdsourcing for Advancing Operations

Q.  Can you give us an update on the STIC incentive grant and the pilot of the Waycare crowdsourced data platform?

Waycare is in the DOT’s procurement process.  Once we have access to the information, the pilot will begin. We hope to see an increased situational awareness of the roadways.

Q.  Once it is deployed, will you have data coming in immediately?

We anticipate that we will have data but we will need to evaluate what that data means to us. For example, a key consideration is the definition of terms such as “crash incident,” and “accident.” We need to determine if we accept what the system’s definition of a term is or if we can set a definition.

Once the Waycare system is operating, NJDOT’s Intelligent Transportation Systems Resource Center (ITSRC), housed at New Jersey Institute of Technology (NJIT), will be working with NJDOT on the evaluation of the information coming in and matching it up with other information that DOT is utilizing.

Next Generation Traffic Incident Management

Q.  Can you update us on the deployment of the Computer Aided Dispatch (CAD) integration with the State Police?  At the 3rd Quarter STIC meeting in September 2021, you mentioned that the State Police had deployed their CAD system and are still doing some fine-tuning.

The State Police deployed their system at the end of June and are continuing to make adjustments to the system and train staff in its use. They will be building out the system by adding modules. We are working with the State Police to determine how we will have access to the information gathered and we are working towards an agreement.

Q.  Traffic Incident Management must require coordination with numerous organizations, yes?

The Department promotes the safety of traffic incident first responders through their Move Over campaign.

Yes, in fact, we just had our statewide Traffic Incident Management (TIM) meeting today where we reported out on what we have been working on, what we will be doing in the next six months, and what help we will need from others. The various participating groups also report out. TIM involves coordination with first aid, EMS, the State Police, the MPOs, municipal fire departments, the Department of Health, and many others. We have been working on the Move Over bumper sticker campaign, and the National Crash Responder Safety Week was in November, so there are a lot of initiatives that we are working on through the year with a purpose of reducing time an incident is on a roadway and keeping first responders safe while responding to an incident.

Q.  Has there been any progress on establishing an Advanced Traffic Management System (ATMS) platform or core software? What are the steps involved? What are you ultimately looking for with this platform?

In our operations centers, we gather data from many systems such as highway cameras, and travel times, as well as other information. The ATMS platform would combine these multiple platforms into one so that NJDOT operators can look in one place for all the information collected. The State Police CAD data could be included in this core software system.

We want one platform for our existing systems and we are also looking towards what we will need in the future. We worked with an engineering consultant firm to determine required elements, desired elements, and future needs. We were looking for a vendor that has a system that was already built and could then be customized to meet the Department’s needs. Any system would need to work with systems that DOT is currently using. We consulted with NJDOT Safety Service Patrol (SSP) and electrical maintenance, among others, to see what future needs they could anticipate. We wanted to cast a wide enough net to avoid missing something that other groups can anticipate now that they would need later on. We also talked to other state DOTs to receive feedback about their systems.  The pandemic slowed progress on this effort and we have not contracted with a vendor yet.

It is anticipated that the platform will be built out through the addition of modular components. This makes it difficult to predict when the platform will be ready to use.

Weather Responsive Management Systems (WRMS)

Q.  Congratulations on receiving the ITS-NJ 2021 Outstanding Project Award for the Weather Savvy Roads project. What is happening with the project?

The Weather Savvy Roads project was a collaboration with many individuals and organizations.  The project has expanded to 23, and soon to be 24, equipped vehicles. Equipped trucks include six Safety Service Patrol vehicles (3 north, 3 south) which operate 24/7, two incident management response (IMRT) trucks which can respond to incidents at any time (1 north, 1 south), and Operations vehicles including 7 snow plow vehicles (3 north, 2 central, 2 south) and pickup trucks used by supervisors who can respond where needed. We are still working on modifications and analysis of the data we have received.

Weather Savvy instrumentation displays atmospheric conditions and a dashboard view of road conditions in real time.

The Mobile Road Weather Information System (MRWIS) provides information on ambient temperature, road temperature, road condition and grip, as well as a windshield view of road conditions. Management can see what the drivers are seeing. The information helps to assess a storm’s duration and intensity while it is ongoing. The data available through the system has helped management make decisions. For example, last winter a Director referred to the system to determine how much longer crews  would need to be out on the road based on conditions, and could predict another two hours commitment.

WRMS can also assist in traffic incident management. Video of an incident, captured by an NJDOT responder truck, provides much more information than a verbal description of an incident scene. The detail can help ensure that individuals in the field can get the appropriate support and get the road back open more quickly.

NJDOT has extended the pilot deadline to June 2022 to include a second winter using the WRMS. This expansion will allow us to test the system on a potentially wider range of weather conditions, and assess the durability of the equipment. Last winter, NJIT analyzed the information we were collecting and found an issue with the data being reported. The vendor had to change their manufacturing process to address condensation issues and we installed replacement sensors.

Q.  What do you anticipate being the next steps?

We are exploring how to bring this system inside the Department. Currently, the Weather Savvy website is hosted by the ITSRC at NJIT.

Other Innovative Initiatives Underway through Research or Other Activities

Q.  Are there non-EDC innovations being undertaken at NJDOT or elsewhere in NJ that should be highlighted to STIC partners? 

Drivewyze® is a phone app that is used to inform truck drivers of upcoming weigh stations, enabling drive-by of weigh stations, and provides in-cab alerts about slowdowns or other road issues. The Department could use the system to alert truckers to specific conditions, such as truck restrictions on snow-covered roadways before they enter the State, to allow truckers to make adjustments. NJDOT is trying the system out for a year to look at the value of the information and what impact it may have.

We are also using video analytics to look at truck parking in the Harding Truck Rest Area during winter storms. Both commercial trucks and Safety Service Patrol vehicles use this rest area, and the space can become overly full and entrances and exits can be blocked. SSP vehicles need to be able to get into and out of the area to respond to incidents and for shift changes. We installed devices in the parking stalls, which provide information indicating when they are occupied, and cameras identify when trucks are parked in non-marked parking spaces. From the data collected, we hope to determine prime times for usage, and we are trying to find a way to communicate with truckers. NJIT is conducting this study through the ITSRC.

NJDOT’s “Weather Savvy Roads” System Receives 2021 Outstanding Project Award from ITS-NJ

The Intelligent Transportation Society of New Jersey (ITS-NJ) recognizes outstanding projects or programs that employ or advance ITS technologies. This year NJDOT’s “Weather Savvy Roads” system, also known as the Mobile RWIS effort, received its 2021 Outstanding Project Award.

NJDOT’s Weather Savvy Roads Program was recently recognized by the Intelligent Transportation Society of New Jersey

NJDOT’s Weather Savvy Roads (WSR) program started with NJDOT’s Mobility Division applying for and receiving NJ’s first federal Accelerated Innovation Deployment (AID) grant.  The concept was to procure and install mobile RWIS devices and dash cameras in 23 DOT snow-fighting vehicles statewide to view real time conditions and guide decisions for allocation of resources during a winter event.

The team is comprised of staff from NJDOT Mobility, NJDOT Operations, the NJIT ITS Resource Center, and technical partners from Vaisala and EAI.  NJIT created a web-based platform where users could view a statewide map and data from the RWIS devices and video from the CCTV6 in real time.

The WSR project was also designed to continue NJDOT’s investigation into cellular strength along NJDOT’s road network. This effort was first evaluated during NJ STIC Incentive grant funded program using iCone devices on SSP trucks. Utilizing a cellular router carrying FIRSTNET cellular capability, the technical team at NJIT is evaluating the strength of this first responder-only focused cellular system to see the various levels of signal strength. The project has shown tremendous benefits after just one winter season with staff across multiple levels of the Department utilizing the web platform to make better informed decisions about staffing and contractor use.

FHWA’s Ray Murphy Presents EDC-5 Weather-Responsive Management Strategies

On April 14, 2020, the NJDOT Bureau of Research hosted a Lunchtime Tech Talk! webinar on "EDC-5 Weather-Responsive Management Strategies." This event featured a presentation by Ray Murphy, ITS Specialist with the FHWA's Resource Center. Under Round 5 of the Every Day Counts (EDC) program, FHWA promotes Weather-Responsive Management Strategies (WRMS) to manage traffic and road maintenance during inclement weather to improve safety and reliability, and minimize environmental impacts associated with weather events. Weather affects: traffic safety, with 21 percent of the nearly 6 million roadway crashes in the past decade related to weather; mobility, resulting in reduced efficiency and productivity; and environmental impacts on watersheds, air quality, and infrastructure.

Mr. Murphy provided examples of weather responsive practices being tried by state DOTs, including an advanced traveler information notification deployed by Iowa DOT.

Mr. Murphy provided examples of weather responsive practices being tried by state DOTs, including an advanced traveler information notification deployed by Iowa DOT.

Mr. Murphy described the prior-round, EDC-4 innovation, Road Weather Management – Weather-Savvy Roads, that formed the basis for this EDC-5 initiative. The innovation promoted data collection including Pathfinder, a collaboration between the National Weather Service, state DOTs, and state support contractors to provide weather information and forecasts, and Integrating Mobile Observations (IMO) that collects weather and road condition data from instruments on agency fleet trucks.

Through WRMS, FHWA promotes the use of mobile data to support decision making. Benefits to agencies include improved safety, system performance and operations, and reduced costs and environmental impacts. Agencies can use Weather Responsive Management Systems to address diverse internal needs such as staffing, material use, and route optimization, and condition and performance reporting. Data sources include transportation agency fleets, private vehicles, third party entities, agency operators, road users and infrastructure. Some data is collected by in-vehicle sensors, video and camera images, and automatic vehicle location. Other data sources include fixed Roadway Information System (RWIS), National Weather Service, reports from road users and operators, mobile observations and connected vehicle data, among others.

The traveling public benefits through safer pre-trip and real-time route decision making based on enhanced traveler information, roadside messaging, variable speed limits, and road lane closures or restrictions. Unified, localized, and more accurate messaging gives the public increased confidence in the messaging and the agency.

Mr. Murphy addressed some common challenges that agencies face in adopting this innovation, such as a lack of connectivity in remote areas, the need for buy-in from agency leadership and from road crews, hesitance to adopt the innovation, and funding.

Mr. Murphy cited some of work that NJ DOT has accomplished in the field of Weather Responsive Management Strategies.

Mr. Murphy highlighted recent initiatives undertaken by NJDOT related to Weather Responsive Management Strategies that have been funded in part through FHWA innovation grants.

He noted that the State Transportation Innovation Council (STIC) Incentive Program and STIC Accelerated Innovation Deployment (AID) grants can help fund implementation of these technologies. NJDOT received a STIC incentive funding grant to support pilot testing of technology used by the Safety Service Patrols. NJDOT was also awarded an AID Grant from FHWA to support a weather savvy roads pilot program, installing video camera dashboards and sensors onto NJDOT maintenance trucks and safety service patrol vehicles to collect streaming video and weather / pavement information to support road weather management throughout the state.

Webinar participants had an opportunity to pose questions of Mr. Murphy. One participant asked about possible resistance to installation of automatic vehicle locators due to privacy concerns. Mr. Murphy noted that agencies must operate openly and inclusively when implementing this technology. Training and education can help users become more accepting of the technology.

A participant asked about the use of IMO data versus information gathered from a public entity such as WAZE. Mr. Murphy responded that the agency receives the IMO data directly and can oversee the accuracy of the data, but that information should come from multiple sources to create a robust dataset.

When asked what agencies consider the biggest challenges, and what arguments can be used to support this innovation, Mr. Murphy responded that funding is always a concern but that buy-in is often the larger issue. He emphasized the need for a champion who can demonstrate the benefits of the strategies through performance measures.

When asked if specific applications of WRMS were being considered for EDC-6, Mr. Murphy responded that various innovative practices were being considered and no decisions had been made yet.

A participant asked if these systems can be adapted to rockfall data. Mr. Murphy noted that visibility apps used with dust storms or fire events could be adapted for other weather events.

Mr. Murphy’s presentation offered several examples of DOTs nationwide employing these strategies. A participant asked if any states are quantifying the benefits of WRMS implementation. Mr. Murphy offered that Caltrans is one agency.

NJDOT Awarded Accelerated Innovation Deployment Grant to Start Weather-Savvy Roads Pilot Program

The Federal Highway Administration has awarded NJDOT a $322,461 Accelerated Innovation Deployment (AID) Demonstration grant to “start a ‘weather-savvy roads’ pilot program to improve roadway safety and operational efficiency.”

Preliminary plans include equipping up to 20 NJDOT road maintenance vehicles with dash-mounted cameras and weather sensors, which will feed real-time data directly to NJDOT year-round. The data will support improved awareness of road conditions and faster response times during weather events.[1] New Jersey’s winter season includes frequent precipitation, making for slick road conditions and added congestion. The data retrieved from the cameras and sensors will help quicken operations and also enhance deployment of incident management strategies.

This is the first AID grant applied for through New Jersey’s State Transportation Innovation Council (STIC). This year, FHWA awarded $8.4 million to nine states for work on innovative highway and bridge projects to improve safety and operational efficiency.

Importance of Weather-Responsive Management Strategies

Weather effects on our nation’s roads have enormous social and economic costs. According to the FHWA, 1.2 million (or 21 percent) of the more than 5.7 million vehicle crashes over the past 10 years were weather-related. Nearly 6,000 people are killed and over 445,000 are injured in weather-related crashes each year. In terms of mobility, the weather is responsible for 25 percent of non-recurring delays as well as congestion costs of up to $9.5 billion per year for 85 urban areas[2] and $3.4 billion in freight costs.

To address these problems, states can implement weather-responsive management strategies, which have many benefits including reducing crash risks and delays, lowering negative environmental impacts by minimizing road salt use, and enabling travelers to make better driving decisions.

In recent years, the FHWA Road Weather Management Program has focused on using mobile observations and connected vehicle data to support traffic and maintenance management. States such as Nevada, Michigan, and Minnesota have already implemented winter maintenance/anti-icing strategies using “Integrating Mobile Observations” (IMO), which involves collecting weather and road condition data from government fleet vehicles. Pathfinder, another solution, is a collaborative strategy across state DOTs to disseminate road weather information for proactive transportation system management ahead of, and during, adverse weather events.

Every Day Counts and State Transportation Innovation Councils

The AID program works closely with the FHWA Every Day Counts (EDC) program to foster a culture of innovation. Every two years, FHWA works with state DOTs and other public and private stakeholders to identify new sets of innovative technologies that merit widespread deployment to address transportation challenges. State Transportation Innovation Councils (STICs) from all fifty states then meet to evaluate these innovations and lead deployment efforts.

Weather management was named a priority in recent years. In 2017-2018 the fourth round of EDC (EDC-4) cited11 innovations including “Road Weather Management – Weather-Savvy Roads.” In 2018-2019, EDC-5 identified 10 innovations including “Weather-Responsive Management Strategies.
