Combined model of trip generation and trip distribution based on destination fascination

Traditional forecasting method of traffic demand is based on the study of traffic zones. Therefore, aggregate error is produced. Trip generation forecasting method use the same average trip generation rate to determine trip generation volume in different traffic zones. The fascination of traffic zones is not considered. In order to reduce the forecasting error produced by different trip generation rate in different traffic zones, influencing factors of fascination of traffic zones were analyzed and the detailed calculation method of trip efficiency and fascination of zones combined with destination model based on disaggregate theory is given in this paper to modify traditional model of trip generation and distribution. A case in Beijing is used to explain the application of the method above.
