现行出租车系统仅以对空载车辆在城市中的定位及可能性安排作为其主要调度方式,造成出租车营运效率低、空载率高、乘客等待时间长且满意度不高等诸多问题.本研究采用浮动车(FCD)数据和地理建模仿真平台,使用地理信息系统(GIS)技术来定量分析给定城市出租车系统的完备以及与需求的合适程度,总结出一套基于出租车运营的系统完备度评价体系,从而实现城市出租车系统的良好组织与管理.该体系主要从城市路网、乘客以及驾驶员等多维指标,来量化给定城市出租车系统的运营状态和效率,合理制定运营调度策略.系统基于深圳市实际出租车数据,在ArcGIS 10平台实现且可按预期功能对城市出租车系统从多方位进行评价,为进一步管控奠定良好的基础与指导意义.

Urban Taxi Goodness Index and System Implementation of GIS

The main scheduling strategy method of existing taxi operation system focuses on the location and possible distribution of idling taxies, which leads to problems as low operation efficiency, high idling rate and long passenger waiting time arise. The taxi operation system encounters a great challenge without a comprehensive evaluation system. Using the floating car data (FCD) and geographic simulation platform, this paper proposes a system to quantify the goodness of existing urban taxi system and the relationship between supply and demand with the assistanceof GIS technology. This evaluation system reflects the overall operation and efficiency in aspects of urban road network, passenger and taxi driver satisfaction, contributing to improving the organization and operation. Based on the one month data obtained from Shenzhen (Dec., 2011), China, an empirical example is provided in the environment of ArcGIS 10. The system performs a good multi dimensional analysis about the existing system, which consequently assists to improve future management efficiency of urban taxi system.
