摘要
在建立了基于固定车头时距策略(constant time-gap,CTG)的自适应巡航系统模型的基础上,着重研究了不同车头时距下的自适应巡航系统对高速公路交通安全及流量的影响。模拟了一个八车队列在不同特殊行车工况下的响应,体现了自适应巡航系统的安全特性。在高速公路管道模型的基础上,讨论了不同车头时距下的自适应巡航系统对交通流量的影响,并对自适应巡航系统的适用条件提出了相应的建议。
The model of Adaptive Cruise Control （ACC） system based on the Constant Time-Gap （CTG） spacing policy was established. The impacts on highway traffic safety and capacity of the ACC system under different headway time were studied detailedly. An ACC platoon with 8 vehicles in several emergency scenarios were simulated to show the safety benefits of the ACC system. The influences of ACC system under different headway time on highway traffic capacity were analyzed based on the ＂Highway Pipe＂ model, and the suitable conditions for the use of ACC system were also proposed.
