公路网合理多路径集合判断方法的研究

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。

A Study on Judgement Method of Rational Multi-Path Set in Highway Net

The previous judgement of rational route is based on the standard-the difference in path distance,such as providing path deletion,path penalty and K-the shortest path method and so on.With the expanding and the vehicle flow increase in highway net,some present methods for judging rational route set have some potential abuses and can not be the judgement basis of fully reflecting path set selected by a driver.A more comprehensive rational route judgement method on the basis of studying present rational route judgement algorithms of city and expressway road-path is presented,and a more comprehensive theory and pratice basis for further rational route judgment is established.
