基于道路拥堵信息的公交出行规划系统

针对当前道路拥堵增多的情况，建立了一个基于道路拥堵信息的公交出行规划系统，以引导公众避开拥堵道路。分析道路拥堵状况的指标体系，分别选取路段和交叉口的通行参数指标，并给出一种红绿灯等待灯次的简便算法，提出公交出行规划方案的拥堵指数算法。以嘉兴市为例，采用SQL＋IIS＋ASP＋Android技术构建了C/S架构的基于道路拥堵信息的动态公交出行规划系统。该系统推荐的出行方案能引导用户避开拥堵道路，提高出行效率，减少出行时间，为公众出行提供了更全面的公交出行信息和更便利的信息获取途径。

Bus Travel Planning System Based on Road Congestion Information

As road congestion increases, a bus travel planning system based on road congestion informa-tion is established for guiding users to avoid congested roads. The index system of road congestion is ana-lyzed, the congestion parameter indexes for roads and intersections are selected, a simple method for counting traffic light waiting times is put forward, and a congestion index algorithm for the bus travel plan-ning scheme is proposed. Taking Jiaxing as an example, SQL＋IIS＋ASP＋Android technology is used to build the C/S-structure dynamic bus travel planning system based on road congestion information. The system recommends bus travel plan which could guide users to avoid congested roads, as well as to ad-vance travel efficiency and to reduce travel time. The implementation of the system for the public provides more comprehensive bus travel information and more convenient access to information.
