Title: A TAXI DISPATCH SYSTEM BASED ON CURRENT DEMANDS AND REAL-TIME TRAFFIC CONDITIONS
Abstract: This research involves the study of the existing taxi dispatch system employed by taxi operators in Singapore to handle current bookings. This dispatch system adopts the Global Positioning System (GPS), and is based on the nearest-coordinate method, i.e. the taxi assigned for each booking is the one with the shortest, direct, straight-line distance to the customer location. However, the taxi assigned under this system is often not capable of reaching the customer in the shortest time possible. An alternative dispatch system is proposed whereby the dispatch of taxis is determined by real-time traffic conditions. In this proposed system, the taxi assigned the booking job is the one with the shortest-time path, i.e. it will reach the customer in the shortest time. This dispatch ensures that customers are served within the shortest period of time, resulting in increased customer satisfaction. The effectiveness of both the existing and proposed dispatch systems is investigated through computer simulations. This study presents and analyzes the results from a simulation model of the Singapore Central Business District (CBD) network. Data from the simulations show that the proposed dispatch system is capable of being more efficient in dispatching taxis more quickly, leading to more than 50% reductions in passenger pick up time and average travel distance. A more efficient dispatch system would result in higher standards of customer service, and a more organized taxi fleet to better meet customer demands
