摘要
随着自动驾驶汽车将会成为道路交通的重要参与者,自动驾驶汽车和手动驾驶汽车所组成的混合交通流会给城市交通系统带来一定的不确定性,本文在对自动驾驶汽车和手动驾驶汽车的驾驶行为进行分析的基础上,提出驾驶行为假设,并对二者在双车道条件下的驾驶行为博弈进行了分析,基于元胞自动机模型对该博弈过程进行了模拟仿真。实验结果表明,随着道路中自动驾驶汽车的比例的增加,交通系统的稳定性随之提高;在一定的车流密度区间内和自动驾驶汽车的占比超越一定比例后,采取将自动驾驶汽车和手动驾驶汽车分流的方式才能有效地提高交通系统的效率。
Aa autonomous vehicles become important participants in road traffic and the mixed traffic flow of autonomous vehicles and hand-driving cars will bring uncertainty to the urban transportation system.On account of the analysis of the driving behavior,this article puts forward the driving behavior hypothesis and analyses the driving behavior game of the two in the two-lane condition.Based on the cellular automaton model,the game process is simulated.The experimental results show that with the increase of the ratio of autonomous vehicles on the road,the stability of the transportation system will be improved.Furthermore,the way that separating the automatic driving vehicle from the manual driving vehicle can effectively improve the efficiency of the transportation system,when the density of vehicle flow is within a certain range and the proportion of autopilot cars exceeds a certain percentage.
