兰州智能公交监控与调度系统研究说明书

摘要

为了减少私家车使用对环境污染、能源消耗，提高公交系统的效率，从而鼓励市民乘坐公交车出行，智能公交系统应运而生了。

本文主要对智能公交监控调度系统进行了研究。首先通过对兰州市智能公交监控调度系统的调查分析，提出了兰州市公交车辆的智能监控调度技术方案；然后以3路、310路公交为应用对象，详细分析研究了公交车辆的智能监控调度系统的实施与应用过程；最后通过3路公交车上行方向各站点的客流量统计，用算法实现了行车计划时刻实时调度表。 关键词：智能公交系统；监控；调度；行车计划；客流量

Abstract

In order to reduce the use of private cars on the environment pollution, energy consumption, improve the efficiency of the public transportation system, so as to encourage the public to take a bus trip, intelligent public traffic system came into being.

This paper focuses on the intelligent transportation monitoring and dispatching system . First by investigating and analysing the City Intelligent Transportation Monitoring and dispatching system in Lanzhou in detail, put forward Lanzhou city public transit vehicle intelligent monitoring scheduling scheme; then apply 3Road and 310road public transit as application object and analyses the public vehicle intelligent monitoring and dispatching system implementation and application process; finally through the 3 bus site traffic statistics in the direction of the car line, achieve e traffic plan moment of real-time schedule tab.

Keywords:Intelligent public transport systems; monitor; scheduling; travel plan; traffic
