Project Abstract:
Despite the significant progress in automated driving, technical challenges still exist, especially for complex Operational Design Domains (ODDs). A low-cost roadside device system, the Connected Reference Marker (CRM) System, was developed to facilitate CAV localization. A project was funded by CCAT FY2024 to build a prototype system and evaluate its performance. The initial results show that the CRM System is capable of maintaining low positional errors and, therefore, has the potential to be a reliable solution for vehicle localization for cooperative driving automation (CDA).

In this project phase, the research team aims to develop a deployable work zone safety system built upon the prototype CRM system from the previous project phase. Specifically, the work zone safety system can track and predict the trajectories of individual vehicles, estimate the vehicle’s collision risk, and send customized warning messages if the risk is elevated. This work zone safety system will also incorporate modules from the CARMA CDA platform to ensure system interoperability.
