Abstract
Taxi is one of the paratransit in the urban public transit systems. Compared with conventional mass transit systems, taxi is featured with convenience, speediness, door-to-door, privacy and comfort. With reasonable fare and high service quality, taxi would be very attractive to private vehicle users and can help of enhancing efficiency and safety of transportation system and reducing environmental pollution. However, taxi is inefficient and gains no brand images under the traditional operation approach of cruising on the streets or waiting at taxi stand,. Although the radio dispatching approach can overcome some problems, it still has the shortcomings of inefficiency, unfair dispatching scheme, the small scale limited by handling capacity and noisy to passengers. In 2001, the Taiwantaxi introduced the GPS/GIS-based intelligent dispatching system, and enhanced the service quality and dispatching efficiency dramatically. Since then, the public authority and several enterprises have explored and deployed similar technology for many taxi companies.
This study aims to evaluate the operation performance of Taiwantaxi and Taichung e-Cab Corporations by Data Envelopment Analysis (DEA) approach. The study develops evaluation model in three aspects including the cost-efficiency, the cost-effectiveness and the service-effectiveness. The CCR and BCC models are used to evaluate the technical efficiency, the pure technical efficiency and the scale efficiency in terms of the three aspects. In addition, this study applies Assurance Region (AR) model to limit the weights of inputs and outputs to overcome the misleading results from traditional DEA models. Finally, a Tobit regression analysis is conducted to assess the influences of environmental factors on operational performance.
The results of empirical study reveal that the two companies have insignificant difference in their performance of cost-efficiency. It is also shown that the performance of Taiwantaxi is better than Taichung e-Cab in terms of service-effectiveness and cost-effectiveness while Taichung e-Cab has a better efficiency in its dispatching center. It is also found that the environmental factors that have significant influence on the service-effectiveness and cost-effectiveness consist of growth rate of taxi, growth rate of real income, number of foreign visitors, growth rate of motorcycle and the region-specific factor. Based on findings, this study proposes strategies for improvement of intelligent dispatching taxi system.
