Safe Transportation for Every Pedestrian (STEP)

What is Safe Transportation for Every Pedestrian (STEP)?

Pedestrians account for over 17.5 percent of all fatalities in motor vehicle traffic crashes, and the majority of these deaths occur at uncontrolled crossing locations (such as non-intersections) or at intersections with no traffic signal or STOP sign. Cost-effective countermeasures with known safety benefits can help reduce pedestrian fatalities in these scenarios.

FHWA promoted the following safety countermeasures through EDC-4 and EDC-5:

Road Diets can reduce vehicle speeds, limit the number of lanes pedestrians cross, and create space to add new pedestrian facilities.

Pedestrian Hybrid Beacons (PHBs) are a beneficial intermediate option between Rectangular Rapid Flash Beacons (RRFBs) and a full pedestrian signal. They provide positive stop control in areas without the high pedestrian traffic volumes that typically warrant signal installation.

Pedestrian Refuge Islands provide a safe place to stop at the midpoint of the roadway before crossing the remaining distance. This is particularly helpful for older pedestrians or others with limited mobility.

Raised Crosswalks can reduce vehicle speeds.

Crosswalk Visibility Enhancements, such as crosswalk lighting and enhanced signing and marking, help drivers detect pedestrians—particularly at night.

NJ's Progress Towards Institutionalizing STEP

Stage of Innovation:
INSTITUTIONALIZED
(January 2021)

NJ's work on STEP began with EDC-4 and continued to progress during EDC-5:

Developed an Action Plan for Implementing Pedestrian Crossing Countermeasures at Uncontrolled Locations. For this collaborative effort, NJDOT and FHWA reviewed existing practice and policies impacting crossings and recommended actions for targeting specific safety countermeasures to help reduce the number and rate of pedestrian crashes, fatalities, and injuries on NJ highways.

Devised Recommendations Following STEP Guidance for Implementing Lower-Cost Countermeasures. The recommended countermeasures can be deployed based on specific needs, have a proven record of reducing crashes, and represent underutilized innovations that can have an immediate impact.

Developed NJ 2020 Strategic Highway Safety Plan. STEP strategies have been included in the 2020 NJ Strategic Highway Safety Plan update, completed in August 2020 and implementation efforts of proposed actions items are underway.

What's Next?

New Jersey has developed strategies in the 2020 Strategic Highway Safety Plan and will implement these strategies with the goal of eliminating all pedestrian and bicyclist fatalities and serious injuries on all public roads.

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.

EDC-4 Final Report Highlights Innovations

The EDC-4 Final Report highlights the results of round four of the Every Day Counts program to rapidly deploy proven innovations to enhance the transportation system. “Every Day Counts: An Innovation Partnership With States” documents progress in accelerating the implementation of 11 innovations in 2017 and 2018 and success stories from States across the country.  View the report’s maps and highlights to learn how innovation implementation was advanced across the country.

New Jersey’s use of “Ultra High Performance Concrete (UHPC)” for the Pulaski Skyway deck replacement in northern New Jersey is a featured “Innovation Spotlight” example in this national report.  The report highlights NJDOT’s use of precast deck panels connected with UHPC, stainless steel rebar, and a polyester concrete overlay to maximize the durability of the new deck and minimize the need for future repairs and traffic disruption.  The project is recognized as the largest user of UHPC to date in North America.  Moreover, in 2012, when NJDOT selected UHPC for the Pulaski Skyway only five other transportation agencies had used UHPC for bridge construction.  Since then, the skyway has served as an informative example for other agencies. NJDOT continues to use UHPC connections and completed five other bridges in 2018, bringing the State’s total to nine bridges.
