摘要
本文讨论了多属性条件下的城市交通网络的路径选择问题。当路径的客观信息已知时,出行者对所关注的属性给出具体的主观偏好值。由于出行者的主观偏好与客观信息之间存在一定的偏差,为了尽可能的减小这种偏差,在此建立了单目标优化模型,并采用解析的方法对模型进行了求解。在此基础上,给出了路径选择问题的求解步骤,其实现过程简单可操作。最后通过算例说明了主观偏好对路径选择结果的影响。
This paper discusses the route choice problem with multi-attributes in traffic networks. Let the known information be the subjective values, and the preferences of passengers to concerned attributes be the objective values. Because there is some error between the subjective and the objective values, a model is set up to minimize it, and the model is solved by the analytic method. Based on it, a simplified procedure is provided to get an optimal path. In the end, an example is given to illustrate the effect of the preferences in route choice.
