摘　　要：分析最小换乘算法比Dijkstra算法更适合基于WebGIS的公交换乘查询.考虑交通路况对出行路径选择的影响,引入站点热度和线路热度,提出换乘次数最少、换乘站点热度最小、出行线路热度最小优先级递减的线路评价指数模型,能够给乘客提供更加合理的最优出行线路,期望在WebGIS得到广泛的应用.To minimum transfer times algorithm was studied,which is more suitable for public traffic transfer inquiring belong to Web Geographic Information System（WebGIS） than Dijkstra algorithm.Taking the traffic condition′s influence on travel route into consideration,bus station heat and route heat index were introduced.A novel route evaluation model was built based on minimum transfer times,minimum changing station heat index,minimum route heat,which could provide more rational optimal travel route for passagers.According to its efficiency and rationality,the model was expected to widely used in WebGIS.
