Method of Traffic Zone Division Based on Trip Distance

Aiming at calculation of traffic zone radius, probability density and probability distribution of trip distance were analyzed. Inner trip proportion, traffic zone radius, trip distance, space between traffic zone center and trip generator, probability of trip distance were defined as P, R, D, S and f(D) respectively. According to the relationship between D and R, three conditions were considered, i.e. D≤R, R2R. Two models among and P and R, D, S, f(D) were established under the condition of D≤R, R2R. The calculating method and procedures of the traffic zone radius based on trip distance were put forward.
