Quantifying Safety Impacts of V2X-Enabled Traffic Systems (Phase 1)

2025 | Systems Analysis and Optimization

Transportation Technologies:

Connectivity: CV, CAV, and V2X, Vehicle Technologies

Impacts:

Safety

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.

Outcomes & Deliverables

Phase 1 Outcome:
A quantitative PRA tool that enables the user to analyze different V2X configurations and identifies major safety concerns regarding technology reliability, connectivity, or deployment assumptions. The goal is to provide a probabilistic tool that can estimate the risk reduction effect of different V2X configurations based on a set of parameters that may be chosen by the user when using the tool.
