| 摘 要： | 为了分析交通流混沌的转化机理,建立了一类新的交通流跟驰模型,并分析了模型的动力学行为.数值模拟结果表明,在这一新的跟驰模型产生的交通流中存在倍周期分岔和混沌.而且系统在经过倍周期分岔进入混沌的过程中,存在跳跃现象,特别是在某些参数下,存在跳跃现象的倍周期分岔还具有一定的周期性,是首次得到的结果.

| Abstract: | In order to analyze the formation mechanism of chaos in traffic flow,the model of a new car-following model in traffic flow theory is proposed and the dynamical behavior of the model is analyzed.The numerical results show that period-doubling bifurcation and chaos exist in the traffic flow arise from the new car-following model.A phenomenon of jump occurs while bifurcating through a route of period-doubling bifurcation.And the special bifurcation takes some periodicity at some special parameters,which is a ... |
