题目：Communicating with Only Two Vehicles Immediately Ahead Boosts Traffic Capacity Sixfold in Connected Autonomous Vehicle (CAV) Platoon

报告人：姜锐教授 （北京交通大学）

摘要：This paper examines the feasibility of deploying a connected autonomous vehicle (CAV) platoon without relying on the information of the platoon leader, which is conventionally considered in the practice. Here, we first conduct real-world vehicle platooning experiments involving five programmable CAVs that communicate with two vehicles immediately ahead. To address the performance degradation when transferring from simulation to real-world CAV operations, we bridged the Simulation-to-Real gap by introducing a stochastic process. This allowed to perform large-scale deployment tests in a realistic simulation environment that incorporates the stochasticity and heterogeneity of CAVs. We then conducted car-following simulations in various perturbance scenarios and typical on-ramp merging simulations under different traffic demands. Our findings highlight that communicating with vehicles immediately ahead enables a long, tight, and stable platoon. In particular, communicating with only two vehicles ahead boosts traffic capacity sixfold. Our research provides valuable insights into vehicle deployment in the forthcoming era of connected autonomous driving.
