摘　　要：在无诱导信息条件下,驾驶员通常依靠近期经验选择出行路径。在行为强化理论基础上,建立了基于有限理性模糊博弈的无诱导信息车辆路径选择模型,得出了不同初始状态下的博弈平衡结果。数值仿真结果表明:在无诱导信息条件下,路网的交通流分布最终会达到理论分析所给出的某种平衡;在某些路网环境下,不发布诱导信息交通流分布能形成良好的稳定博弈平衡,但在某些路网环境下,路网交通流分布会形成非稳定博弈平衡,不能充分利用整个路网的通行能力,需要采取一定的管理措施。Under the condition of no guidance information, drivers often choose travel route depend on recent experience. Based on the theory of behavior reinforcement, we established the vehicle routing model without guidance information based on finite rational fuzzy game, and the game equilibrium results under different initial conditions are obtained. The numerical simulation result shows that （1 ） under the condition of no guidance information, the traffic flow distribution of road network will eventually reach a balance which is given by theoretical analysis; （2） in some road network environments, the traffic flow distribution can form a good stable equilibrium game without release the induction information, however, in some other network environments, the traffic flow distribution will form a non-stable equilibrium game, the traffic capacity of the entire network is inadequate utilized, and certain management measures should be taken.
