基于WebGIS的城市公交换乘查询系统的研究

Study on Inquiry System for Urban Public Transport Transfer Based on WebGIS

公交是市民出行最为普遍的选择,为方便市民以公交方式出行,采用基于逻辑的搜索算法研发出基于WebGIS的城市公交换乘查询系统,市民出行前,在电子地图上选择起始点和目的点后,系统自动生成多种公交换乘方案供参考,包括换乘次数最少或费用最省等.介绍了公交换乘算法原理,给出了系统结构及各模块的实现,并分析了系统的性能;通过实际测试表明,系统方案可行,运行良好.

Public transport is the most popular trip mode. For the sake of residents convenience to take bus, an inquiry system for urban public transport transfer based on WebGIS is developed according to SQL. First, the principle of public transport transfer Algorithm is introduced, then system structure and implementation are proposed, and finally system performance is analyzed. Tests and applications show that the project is feasible.
