Abstract:

This paper built a day-to-day evolution model based on reference point, which reflected the influence of travelers' feelings on the estimated travel time and route choice by comparing real travel time with reference point. In the estimated time model, the different attitudes towards loss and gain that travelers hold were reflected by different value of parameters. Three cases of travelers' attitudes,which were optimistic,pessimistic and neutral behaviors,are discussed to analyze the influence on evolution process and total travel time. The evolution results indicated that total travel time was maximum when travelers were pessimistic and total travel time was minimum when travelers were optimistic. This research helps to understand the essential laws of urban traffic flow evolution.

Key words: urban traffic, route choice, route flow, traffic flow evolution, reference point
