基于双层博弈的交通方式选择

交通方式选择与交通资源配置的关系是交通领域理论研究的一个重要问题。为了使有限的道路资源得到充分合理的利用,在只考虑公交和私家车两种出行方式的情况下,建立双层博弈模型。其中上层以社会收益最大化为目标,描述了交通管理者和出行者之间的博弈关系;下层反映了公交出行者与私家车出行者之间的博弈均衡。最后用三步法求解模型,并通过算例说明该模型与算法的应用。

Choice for travel modes based on the two-level game

The relationship between the choice of travel modes and traffic resources configuration is an important problem of transportation theory.Only two types of travel modes,namely,autobus and private car are considered,and a two-level game model has been formulated with the purpose to make reasonable and sufficient use of the limited traffic resources.The upper level of the model aims to maximize the total social profit,which describes the relationship between administrators and travelers;the lower level reflects the game equilibrium of the autobus travelers and the private car travelers.Finally the three-step method is adopted to solve the model.At last the application of the model as well as the algorithm is illustrated by a numerical example.
