先前的合理路径的判断是以路径之间的距离差别作为判断标准,如给出了路段删除、路段惩罚、K-最短路径等方法;但是随着路网的扩展以及路网中车流量的增加,现有的一些判断合理路径集合的方法存在着一些潜在的问题,作为判断依据并不能够全面地反映出行者选择的路径集合。本研究结合目前城市路网以及高速公路路网中常用的合理路径集合判断算法,给出一种更加综合性的合理路径集合判断方法。为进一步的合理路径集合判断建立更加全面的实践和理论依据。
Judgment of the previous reasonable path is based on the difference of the distance between the paths as the judgment standard. For example, the method of deleting the section, punishing the section and K-shortest path is given. However, with the expansion of the network and the increase of traffic in the network There are some potential problems existing in the existing methods for judging the set of reasonable paths, which can not fully reflect the path set selected by the traveler as a basis for judgment. In this study, we present a more comprehensive method of judging the set of reasonable paths by combining the common set of judgments of rational paths in urban road network and expressway network. Establish a more comprehensive practice and theoretical basis for further judgments of reasonable path aggregation.
