Abstract To study the advance distance of guide signs of expressway exit, we divide driving behavior in expressway exit into five processes according to the characteristics of the driving psychology principle and drivers' response to signs. A model of guide signs of expressway exit is built to calculate the advance distance of guide signs that meets safety and comfort requirements. The proposed model is established on the basis of the insertion gap travel distance model and isokinetic deviation sine curve model of vehicle lane changing distance. Through the analysis of the setting mode of guide signs, we calculate a reasonable distance for guide signs under different road conditions and different driver characteristics. The proposed model is developed with the UC-win/road and simulated by the Forum8 driving simulator. Simulation results show that only the distance of the advance signs of a two-way four-lane expressway exit is close to the specified value of Road Traffic Signs and Markings, which is reasonable; while for expressway with six lanes and above, the specified value is small.

Key words： traffic engineering advance distance of signs calculating model time headway lane changing model expressway exit lane
