智能网联车辆混行交通流效益研究

Research on Benefits of Mixed Traffic Flow of Intelligent Connected Vehicles

为研究智能网联车辆与非网联车辆的混行交通流效益,针对智能网联车辆的“智能化”与“网联化”2种特性,通过对微观交通仿真软件Vissim进行二次开发,使其具备智能网联车辆交通流建模功能,仿真了不同市场渗透率条件下智能网联车辆与非网联车辆构成的混行交通流,通过对比不同时段及不同渗透率情况下的交通效益发现,随着智能网联车辆市场渗透率的增加,道路混行交通流的平均车速有明显增加,出行时间降低。通过对高峰和平峰期的交通效益敏感性分析,发现智能网联车辆在高峰期对道路交通流产生的效益较平峰期更为显著。

In order to study the benefits of the mixed traffic flow Intelligent Connected Vehicles(ICV)and non-connected vehicles,aiming at the intelligent and connected characteristics of ICV.Through the microscopic traffic simulation software Vissim redevelopment,ICV having the function of intelligent connected vehicles traffic flow modeling is realized.The mixed traffic flow composed of intelligent connected vehicles and non-connected vehicles under different market penetration rates is simulated.By comparing the traffic benefits at different time periods and different penetration rates,it is found that with the increase of the market penetration rate of intelligent connected vehicles,the average speed of mixed traffic flow increases obviously and the average travel time decreases.Through the sensitivity analysis of traffic benefits during peak and non-peak periods,it is found that the benefits of intelligent connected vehicles on road traffic flow during peak periods are more significant than those during non-peak hours。
