摘要
提出了基于 GIS等时线分析方法的理论模型 ,以城市公共交通运输系统的主要工具——公共汽车和城市火车为例 ,描述了等时线分析的设计原型 .在研究静态最短路径算法的基础上 ,讨论了用分解法计算最短有向路径思想 。
Through the analysis of the urban public transportation system, a new theoretical model based on GIS isochrone approach is put forward and a design prototype is described with an isochrone analysis. Based on static state routing algorithms, it discuses a computing idea of the shortest routing using decomposed method. At last, a dynamic optimized algorithm and its solving step are given.
