公交车作为现代城市生活中一种重要的交通工具，在现代城市生活中尤其重要，公交线路繁多，数量也逐渐增多，这样使得人们的出行很不方便。在这样的背景下，我们决定做公交查询系统，并以六安市公交数据为例,设计了公交查询系统,验证了一些算法的可行性。该算法基于对经典的算法的学习和研究,沿用其关于求最短路径的思想,并加以对换乘次数，站点范围限制等内容的深入研究而提出的。-Bus as an important means of transportation in modern urban life in modern urban life, especially important, many bus lines, the number is gradually increasing, which makes people travel very convenient. In this context, we decided to do query system bus, and bus data of Lu' an City, for example, design of public transport query system, verify the feasibility of some of the algorithms. The algorithm is based on the classical algorithm learning and research, to follow its thinking on the shortest path, and in-depth study of the transfer times, and site-wide restrictions proposed.
