摘要:
在研究跟随状态中车辆运行特性的基础上,提出了一种新的跟车模型.与传统的跟车模型相比,新模型考虑了车辆的长度,并将传统模型中的期望间距转换为期望车头时距,反映了后车速度对跟车状态的影响.采用实际道路上的车辆跟车数据,在Simulink环境下,对2种跟车模型进行了仿真分析,结果表明在一定程度上,由于考虑了更多实际情况,新模型优于传统模型.为了能反映车辆在实际中加速、减速以及不同跟车类型的差异性,给出了进一步改进新模型的方向.
Abstract:
A new car-following model based on the study of the characters in car-following state is proposed. Compared with the traditional model, the new one considers the length of cars and the desired space headway is transformed into the desired time headway which reflects the car-following state affected by the speed of following car. Under the condition of Simulink, both the new and the traditional model were simulated by using field data obtained from an actual road. The results show that to some extend, the new model is better than the traditional one because more actual traffic conditions are considered. In order to reflect the difference of acceleration and deceleration and the types of following cars, some further improvements to the new car-following model are introduced.
