高铁车站接驳公交灵活线路优化设计研究

Optimization Flexible Route Design for High-speed Railway Station Feeder Bus

目前高铁车站接驳公交仅服务离开高铁站的乘客,在回高铁车站时空车驶回造成极大的资源浪费.本文设计了一种考虑回程的服务去往,以及离开高铁车站乘客的接驳公交服务模式,即"高铁快巴"灵活线路,区别于常规模式的固定线路,根据乘客预先提交的出行需求生成灵活型"伞状"线路,以车辆行驶时间最少为目标,通过站点拆分,构建灵活线路优化设计模型,运用IBM ILOG CPLEX进行求解,通过案例验证了模型的有效性,在合理的时间内求解出车辆的行驶路径.当根据乘客提交的需求设计出车辆行驶路由后,系统会将车辆到站时间发送给乘客,乘客根据到站时间出行,方便了乘客的出行.

Currently, the feeder bus only served passengers leaving the high-speed railway station. The vehicles can’t serve any passenger when it returned to the station caused huge waste of resources. A feeder bus service mode is designed to serve the passengers leaving or coming to the high- speed rail station which is namely the "high- speed railway station rapid feeder bus" flexible route. Different from the regular fixed route, a flexible "umbrella" route is formed according to the passenger's pre- submitted demand. A bus route design model is proposed with an objective of minimizing total bus travel time and solved by IBM ILOG CPLEX. A numerical example is given to prove the validity of the model in a reasonable time. Passengers could be aware of the bus’s arriving time when the route is formed so that it is very convenient for the passenger.
