Abstract: When the traffic policy changes, the responses of private car commuters with different household income will be different. In order to study the difference quantitatively, Logistic model was used to study the factors which influenced the commuter trip rate of private car in Guangzhou on the basis of the SP/RP investigation. And the impact of parking fees, fuel costs and the waiting time of buses on the commuter trip rate of private car with different household income were explored respectively. All models passed the parameter tests and the fitting goodness tests. Research results declare that the impacts of different factors on the commuter trip rate of private car were significantly different. Under the same range of changes, the adjustments of fuel costs, parking fees, and the waiting time of buses were successively reduced. The research models can assist the traffic managers to formulate private cars transportation demand management policies, and can also be used to evaluate the effectiveness of policies.
