中文摘要：
采用双车道元胞自动机模型,分析了考虑驾驶心理的城市道路交通流特性.针对驾驶员在城市道路行驶时在换道与减速制动方面的不同心理,分别引入了反映驾驶心理的选择换道概率Ps与安全参数λ.通过计算机模拟,给出了不同选择换道概率与安全参数条件下的车辆速度、密度与流量间的关系,并分析了不同驾驶心理对于交通系统的影响.研究发现：选择换道概率对交通流的速度影响并不明显,但选择换道概率的增大会导致速度的方差增大而降低行车安全;而安全参数的增大可以获得更快的平均车速和更大的交通流量.
英文摘要：
A two-lane cellular automaton model is developed to analyze the urban traffic flow with considering the influence of driving psychology.In order to show the different psychological characters of drivers when changing lane and braking,lane-changing choice probability and safety parameter are introduced.By computer simulation,the relationships among speed,density and traffic volume are given to show the influence of driving psychology on the traffic flow.The simulation results indicate that the lane-changing choice probability has little effect on the average speed,but it makes the variance of speed larger.And the safety parameter can increase the average speed and the traffic volume.
