Optimal Fleet Size of GPS-Taxi in a Cruising Taxi Market

With the rapid development of information and communications technologies,GPS-taxi has become a new trend because of the distinguished operation performance when the driving cost of taxi drivers is rising rapidly.Additionally,public authority has encouraged taxis to be equipped with GPS for implementation of automatic dispatching services for real time and dynamic monitoring.This study aims to explore the optimal fleet size of GPS-taxi in a cruising taxi market.A mathematical model with a bi-level programming framework is developed to represent the interaction of maximum welfare objective for public sector and maximum profit objective for private sector.The model has also included features of competition and cooperation between the GPS-taxi and conventional cruising taxi modes.The optimal number of taxi and the optimal ratio of GPS-taxi can then be obtained.Numerical analysis results of Taipei metropolitan might support the authority to implement the policy of quantity regulation and application of innovative technologies.
