A macroscopic taxi model for passenger demand,taxi utilization and level of services 总被引:1,自引:0,他引:1
In most urban areas taxi services are subject to various types of regulation such as entry restriction and price control.
However, effective intervention depends on generating and using suitable information on the demand-supply equilibrium of the
taxi market. This paper develops a simultaneous equation system of passenger demand, taxi utilization and level of services
based on a taxi service situation found in the urban area of Hong Kong over the last ten years. A set of variables is introduced
including number of licensed taxis, taxi fare, disposable income, occupied taxi journey time as exogenous variables and daily
taxi passenger demand, passenger waiting time, taxi availability, taxi utilization and average taxi waiting time as endogenous
variables. These variables are coupled together through a system of nonlinear simultaneous equations whose parameters are
estimated from survey data. The simultaneous equation system can be used to obtain useful regulatory information to assist
with the decisions concerning the restriction over the number of taxi licenses and the fixing of the taxi fare structure as
well as a range of service quality control.

This paper introduces the taxi route network design problem (TXRNDP) for a fixed‐route taxi service operating in Iran and, in similar form, in various other developing countries. The service operates fairly similar to regular transit services in that vehicles are only permitted to follow a certain predetermined route on the network. The service is provided with small size vehicles and main features are that vehicles only depart if full and that there are no intermediate boarding stops. In Iran the service attracts a high modal share but requires better coordination which is the main motivation for the present study. We develop a mathematical programming model to minimize the total travel time experienced by passengers while constraining the number of taxi lines, the trip transfer ratio and the length of taxi lines. A number of assumptions are introduced in order to allow finding an exact rather than heuristic solution. We further develop a linear programming solution to minimize the number of taxis required to serve the previously found fixed‐route taxi network. Results of a case study with the city of Zanjan, Iran, illustrate the resulting taxi flows and suggest the capability of the proposed model to reduce the total travel time, the total waiting time and the number of taxi lines compared to the current taxi operation.
