Travel Frequency Calculation Based on Trip Decision Analysis

Overlong travel time caused by unreasonable departure frequency of bus is a key factor for low transit trip ratio in many medium-and-small cities of china presently,so it is necessary to study how the departure frequency influences transit trip decision.Based on the resident trip survey data,the authors analyzed the trip decision influencing factors,established a BL model that exists bike and transit selection schemes according to the random utility theory,and solved the BL model with Newton-Raphson method under MATLAB program environment;Then the corresponding relation between the transit trip ratio and departure frequency was obtained,by which the reasonable departure frequency can be determined under a given transit trip ratio.A calculation example was done,which proved the method proposed in this paper is practical in determining the departure frequency as well as evaluating the dispatching schemes.
