城市外围非高峰期实时预约公交系统研究

Study on real-time bus reservation system in urban periphery during off-peak period

针对居住在城市外围的人们在非高峰期出行时,公交系统的运营效率及运营成本与乘客等待公交时间的矛盾问题,本文提出了一种基于网约车思想利用手机APP实时预约公交的系统模式。在新请求出现时实时预约公交调度系统会先根据公交系统服务阈值筛选出符合条件的公交,再利用启发式最短路径算法为距离新请求点由近至远的公交依次进行响应路径规划,并结合响应判断函数计算对应公交的响应效益,然后指派首个效益为正的公交作为新请求的响应公交,最后调度系统会将响应公交的信息实时反馈到乘客APP。本文以重庆市外围地区的169路公交为研究对象,验证实时预约公交系统的可实施性,并得出该系统模式在城市外围非高峰期可以进一步完善公交运营系统且满足乘客出行需求。

Aiming at the contradiction between the operation efficiency and cost of the public transportation system and the waiting time of passengers during the off-peak period for people who live in the periphery of the city,this paper proposes a system mode based on the idea of using the mobile phone APP to reserve the bus in real time.When the new request appears,the real-time reservation bus dispatching system will first select the eligible bus according to the service threshold of the bus system,and then the heuristic shortest path algorithm is used to regulate the travel paths of the buses whose distance to the new request ranges from near to far.Then the response judgment function is used to calculate the corresponding bus response efficiency,afterwards assign the bus whose response benefit is the first positive as responsive bus.Finally,the dispatching system can provide real-time feedback to the client APP.This paper takes No.169 bus in the periphery of Chongqing as the research object,verifies the feasibility of the real-time bus reservation system,and concludes that this system model can further improve bus operation system and meet passengers’travel demand in urban periphery during off-peak period.
