Quantifying safety impacts of V2X-enabled traffic systems (Phase 2)

Problem Statement

There is a significant interest in researching methods to improve V2X cost-benefit analysis (CBA) and the development of a decision support tool for deployment for different stakeholders. To develop a framework that allows the assessment of the safety and traffic impacts of V2X technology and provides actionable insights for deriving safety, reliability, and connectivity requirements.

Phase 2 aims to advance, extend, and communicate a structured, context-sensitive framework for quantifying and visualizing the safety impacts of V2X-enabled traffic systems. Building upon previous work, this project will refine and expand the safety impact assessment framework and develop a deployment visualization tool to support state and local infrastructure investment decisions. Phase 1 provided a model-based approach to estimate safety impacts of V2X in collision avoidance scenarios and developed the initial version of the Mobility PRA web tool.

Phase 2 will focus on:

• Improve V2X reliability and deployment assumptions
• Expand V2X applications and modeled scenarios
• Incorporate new impact metrics
• Develop a GIS-based interface risk-informed decision-support tool
