Improve Safety of Vehicles and Vulnerable Road Users at Intersections Integrating C-V2X and LiDAR Sensing Technologies

Crash risks associated with permissive left turns (PLTs), vulnerable road users (VRUs), and wrong way driving (WWD) appear to be among the top attributing factors for fatal and incapacitating crashes at signalized intersections, raising alarming safety concerns. The cellular vehicle-to-everything (C-V2X) communication and innovative traffic detection technologies such as light detection and ranging (LiDAR) sensing have the potential to reduce crashes related to these factors and enhance intersection safety. The research team will develop, test, and demonstrate a prototype system integrating C-V2X communication and innovative traffic detection technologies to improve safety of all road users at signalized intersections. Another objective is to provide the Texas Department of Transportation with guidelines for statewide implementation of the integrated system for intersection safety improvement. The research team will: (1) Review the literature on safety improvement systems utilizing C-V2X and innovative traffic detection systems; (2) Assess user needs and design a system architecture that satisfies user requirements; (3) Develop, test, demonstrate, and evaluate a prototype system that integrates C-V2X communication, LiDAR and other advanced traffic detection technologies to detect and mitigate crash risks involving PLTs, VRUs, and WWD at signalized intersections; and (4) Develop guideline documents containing implementation procedures and use case scenarios.
