Effect of Taxi Information System on Efficiency and Quality of Taxi Services

Abstract

In many major metropolitan areas, taxi services have played an important role as a semipublic transportation mode without public support. However, there has not been much modeling effort-despite the importance of taxis in urban transportation systems-mainly because of the difficulty in modeling taxi drivers' behavior. This study models a taxi service system in urban areas, taking into account taxi drivers' knowledge of the transportation network built from their day-to-day experience. Passenger-seeking behavior by taxi drivers is modeled on the basis of their expected travel time and expected waiting time. The model considers the stochastic and dynamic transportation network and various levels of network knowledge on the part of drivers. This modeling approach provides flexibility in modeling the characteristics of taxi operation as well as understanding how taxi drivers' capability evolves. The study analyzes the fleet size of taxi service systems and the effects of the taxi company's information systems...
