Abstract

In real road-network people’s travel path is different to those models such as Moore Model, Label Model, and Dijkstra etc. This paper gains the rules of people travel path choosing behavior through special survey. Using these rules can simulate the behavior of individual choosing the travel route accurately. This paper attempts using these rules on multi-path assignment model in urban transportation, and introduces control parameter of effective path which can control the assignment result’s precision degree. The model based on real road-network is linearity correlation with the degree of road network, and can reduce the calculate cost and complexity compared with former travel route choosing model.
