A Cooperative V2V Alert System to Mitigate Vehicular Traffic Shock Waves

This project will address the problem of shockwave formation in uncoordinated highway traffic. The problem is caused by the combination of heavy traffic and small traffic perturbations or unexpected drivers actions. In previous work, the project developed an innovative distributed communication protocol that helps mitigate upstream shockwave formation even with extremely low system penetration rates. Based on traffic information ahead, the Cooperative Advanced Driver Assistance System (CADAS) recommends non-intuitive velocity reductions in order to redistribute traffic more uniformly and eliminate traffic peaks. Simulation results have shown that CADAS significantly increases the average velocity and reduces the overall travel time and avoids unnecessary slowdowns. In this follow up project, for realism, we propose to apply CADAS to real traffic traces. Also, the project will extend the shockwave model from single to multiple lanes (to reduce accidents caused by lane switching).
