交通冲击波是造成道路通行能力低下和交通拥堵的主要原因之一。本文试图回答交通冲击波缓解系统发展中的一个重要问题：将人类驾驶的车辆作为系统的一部分是否可行？为了回答这个问题，我们开发了一个实时速度咨询系统，利用车对车（V2V）通信和直观的用户界面，使驾驶员能够主动匹配前方车辆的速度。实际测量结果表明，该速度咨询系统可将反应延迟降低76.4%，将连续两车之间的距离标准差降低40.7%。研究结果为该问题提供了积极的答案，并表明在不久的将来，交通冲击波缓解可以在占车辆数量最多的人类驾驶车辆上有效实施。
Traffic shockwave is one of the major causes for low road capacity and traffic jams. This paper seeks to answer an important question in the development of a traffic shockwave mitigation system: is it feasible to have human-driven vehicles as part of the system? To answer the question, we developed a real-time speed advisory system, utilizing vehicle-to-vehicle (V2V) communications and intuitive user interface, so that the driver can actively match the speed of the vehicle directly in front. Real-world measurement results show that such a speed advisory system can reduce the reaction delay by as much as 76.4% and reduce the standard deviation of the distance between two consecutive vehicles by as much as 40.7%. The results imply positive answer to the question, and suggest that traffic shockwave mitigation can be effectively implemented on human-driven vehicles that accounts for most vehicle population in the near future.
