摘要
跟驰模型是交通流理论的研究热点。在分析了目前交通流跟驰理论的基础上,探讨了信号灯对车辆跟驰行为的影响,提出了改进的交通流跟驰模型.该模型以信号控制交叉口为主要研究区域,以车头间距和信号灯颜色状态作为输入,以车辆跟驰状态为输出,从而建立了分段函数模型,并用仿真软件进行了实验验证,结果证明了模型的可行性。最后,对该研究方向进行了展望。
Car-following model is a hot-study point of traffic flow theory. This paper discussed traffic signal＇ effects on car- following behavior, then brought out an improved car-following model based on analysis of current traffic flow theory study. This model mainly studied signal controlled cross. It had the lead-in car distance and signal state as input variables and car-following state as output . The simulation results showed its feasibility. We advised further study prospect.
