定时、定线路上下班拼车方案实现与评价——以淮安为试点

因信息不畅、费用不统一、违法犯罪时有发生和法律界定不明确等问题,导致私家车拼车市场发展缓慢.设计了以淮安为试点的定时、定线路上下班拼车方案,搭建了拼车信息平台,实现了拼车的信息检索、信息配对、双方互选、双方互评等功能,并利用时间费用阻抗评价模型和Vissim仿真对该实施后的方案进行评价,结果表明该方案可使时间费用阻抗减少65%~86%,拼车路网中平均车速提高17.83%、总停车延误时间减少34.84%、总行驶时间减少28.29%、总延误时间减少40.89%、平均延误时间减少29.23%.方案在淮安试点表明,该方案能较大地减少拼车过程中的出行时间和出行费用,改善拼车区域路网交通拥堵状况,提高拼车过程的安全性和经济性. 

Realization and Evaluation of Commuting Carpooling Program Based on Fixed Time and Route: a Case Study of Huai'an

The carpooling problems,such as unsmooth information,inconsistent fees,crimes and the indeterminate legal definition,etc.,have resulted in the slow development of the private carpooling market.Taking Huai＇an as a pilot program,this paper designs a commuting carpooling program based on fixed time and route,and builds the carpooling information platform to implement the carpooling functions such as information retrieval,information matching,mutual selection and evaluation,etc.Then,the paper evaluates the program after implementation by using a time cost impedance evaluation model and Vissim simulation.The results show that the program can reduce 65% -86% of the time cost impedance,increase 17.83%of the average speed in the road network,reduce 34.84%of the total stopped delay,28.29%of the total travel time,40.89%of the total delay time and 29.23%of the average delay time.The program experimented in Huai＇an shows that it will greatly reduce the travel time and costs of the carpooling,reduce the traffic congestion of the network,and improve the security and economy of the carpooling process.
