* Workshop description information*

Safe System Approaches to Reduce Head-On Crashes

Head-on crashes are violent events that result in thousands of fatalities around the world each year. In the United States, head-on crashes, account for over 5,000 fatalities which is approximately 14% of all fatalities between 2018 and 2020. These crashes typically occur on high speed, undivided rural roads.

In Australia, around 17% of fatalities are head-on collisions and approximately two thirds of all road deaths occur in regional and remote areas.

With the Safe System Approach, this is unacceptable and since we know that humans make mistakes and our bodies are vulnerable when subjected to the forces of a head-on crash, action is needed to provide more than a pavement marking to separate vehicle traveling in the opposite direction.

There are countermeasures that have been proven to reduce these crashes. These countermeasures include treatments like centerline markings and rumble strips that help drivers stay in their lane, the SafetyEdge^SM and wide buffer areas to reduce the potential for a crash if they do leave the lane and barriers to minimize the severity of crashes that do occur. Effective countermeasures on some rural roads of Australia have included installation of median wire-rope barriers but where costs are prohibitive, speed limits have been reduced to survivable Safe System impact speeds. These countermeasures can be deployed proactively and in combination to provide redundancy.

This workshop will examine strategies and evidence base of their effectiveness for deploying these countermeasures to provide for a safer system.

Building on Successes of Managing Pavement Friction to Support Safety Performance and Safer Roads - An International Perspective

Pavement friction is an essential fundamental factor related to the safety performance of a roadway. Pavement friction management is a FHWA Proven Safety Countermeasure and supports the Safe System Approach. The interaction between a vehicle and the roadway pavement surface creates friction which allows drivers to safely perform vehicle steering, stopping, and acceleration maneuvers. These are important elements in reducing crashes related to roadway departure, intersections, and pedestrians.

For decades, countries outside of the U.S. have been measuring, monitoring, and managing pavement friction and it an integral component of determining when, where, and how safety interventions need to take place.

This workshop will present the latest international efforts by multiple counties to manage pavement friction to support improved safety performance. It will include information on crash modification factors, measurement of pavement friction on curves and its relationship to safety performance, and other successful practices.

Current Methods for Risk-Based Safety Planning

Workshop will explore proactive, risk-based methods of safety planning. Participants will learn from examples where the systemic approach to safety has been used to identify optimal locations to deploy low-cost safety countermeasures. Data sources that can support a systemic safety study can go beyond crash data – alternative sources such as LiDAR and roadway attribute inventories will be discussed. This topic will continue to be discussed in an afternoon workshop titled “Future Methods of Risk-Based Safety Planning

Management of Road Safety and Institutional Development in Low and Middle-Income Countries

The proposed workshop as a master class is aimed at engaging a discussion about road safety management in developing countries and strategies for capacity building and technical knowledge sharing. The outcome of the discussion would be for participants from developing countries to understand a global framework that can be applied to individual country/sub-national context for results-based road safety implementation with necessary institutional and governance mechanisms in place. The session would highlight examples from developing countries that provide an opportunity to understand the constraints and opportunities under the road safety management framework. The session would also highlight the role of multi-lateral development partners and other international organizations to collaborate in this multi-sectoral effort to reduce traffic crash related deaths in line with the UN SDG goals.

Safer Roads through Management of Pavement Friction and Safety Performance

Pavement friction is an essential fundamental factor related to the safety performance of a roadway. For decades, countries outside of the U.S. have been measuring, monitoring, and managing pavement friction and it an integral component of determining when, where, and how safety interventions need to take place. Pavement friction management is a FHWA Proven Safety Countermeasure and supports the Safe System Approach. The interaction between a vehicle and the roadway pavement surface creates friction which allows drivers to safely perform vehicle steering, stopping, and acceleration maneuvers. These are important elements in reducing crashes related to roadway departure, intersections, and pedestrians.

Recent research in the U.S. has focused on developing safety performance functions (SPFs) that include continuous friction and macrotexture measurements on a variety of roadway facility types and categories (i.e., segments, intersections, curves, and ramps). The main objectives were to obtain crash modification factors (CMFs) that make possible the evaluation of pavement friction changes on safety performance and to establish investigatory thresholds for friction based on roadway type and category. The analysis confirmed a strong statistical association between pavement surface frictional properties (friction and macrotexture) and crash rates. As expected, the investigatory levels are higher for higher friction demand sites, such as curves, ramp and access points, and intersections. States have begun to implement this research and are using it to identify and prioritize locations for friction enhancement to address roadway departure crashes. Internationally, there is interest in adding SPFs into their strategic approach to pavement friction management. This workshop will present the approach to developing SPFs and CMFs, establishing investigatory thresholds to improve safety performance, and provide the experience of DOTs with this process as well as the experience from the international perspective. This workshop provides an opportunity to share and transfer knowledge of integrating pavement friction into safety practices. It would allow attendee interaction and discussion of research and practice.

Future Methods of Risk-Based Safety Planning

Participants will get hands on experience with 360-camera technology and demonstration of computer vision that can create safety risk data -- even where no data currently exists. Case studies will demonstrate how such data has been used in risk-based safety planning to equitably address the roadway departure component of FHWA’s Focused Approach to Safety.

This workshop will continue the discussion of using alternative sources of safety data including LiDAR, imagery, GIS methods, usRAP, and more.
