摘要：
The cumulative function relationship between route choice probability and route impedance is derived from the original logit model by utilizing the relative impedance instead of the absolute impedance of the model. The well-known least squares method, which has the advantage of computational simplicity, could be used for the estimation of logit parameter. The estimation of logit diversion parameter is tested by using the curve fitting method and the route choice data collected in central district of Guangzhou city from taxies equipped with GPS. Results show that it is a practical way for parameter estimation of logit model.
