摘要/Abstract

摘要： 在入口匝道合流区,驾驶员通过观察运行环境及估计周边车辆行驶特征,做出的相应的驾驶决策,常会使车流紊乱。针对该问题,从车车通信环境下获得的周边车辆运行全信息入手,建立上匝道合流影响区车辆决策机制模型,并更新了新决策机制情况下运行规则。数值试验分析车辆在两种不同环境下的时空轨迹图、合流区及上游换道情况、平均行程速度。结果表明:在车车通信环境及决策机制模型条件下,合流区只有很低水平的换道;平均行程速度最大提高了32.4%,在不同车辆输入情况下速度波动降低了76.7%,通行能力提高了13.3%。

Abstract: In the on-ramp merging area, appropriate driving decisions should be made by observing the running environment and estimating the driving characteristics of the surrounding vehicles, which usually led to the inordinate traffic flow. To solve this problem, the decision strategy models were built for vehicles in the on-ramp merging area, and the operating rules for the new decision strategy were updated. Furthermore, the space-time trajectory, the lane changing in merging and upstream area and the average speed in the two different circumstances were analyzed by numerical experiments. The results show that in the condition of vehicle-vehicle communication environment, where there are a few lane changing phenomena; the average speed increases by 32.4% maximally, and in different vehicle input circumstance the speed fluctuation decreases by 76.7%, the traffic capacity increases by 13.3%.

Key words: vehicle-vehicle communication, merging area, decision strategy models, operating rules
