Research into the driver’s route choice under existing real-time traffic information

The research of driver¿s route choice behavior helps to increase utility of existed route network (especially city traffic network), and improve traffic conditions. From the point of macroscopic view, through discussing the time evolution pattern of driver´s route choice behavior with the influence of dynamic traffic information upon the pattern, it is proved that the behavior of route choice is uncertain. So in designing traffic guiding system or traffic information system, the influence of disturbing factor should be taken into consideration to guarantee a balanced dynamic traffic distribution of the system.
