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.
