摘要：
Based on the driving simulation experiment, four variable message sign (VMS) frontal distances of 3.0 km, 2.5 km, 1.5 km, and 0.7 km were set, and the steering wheel, speed and position data of 32 drivers were collected during the process of changing lane and leaving freeway after the recognition of VMS with four frontal distances. Then, the steering behavior, lane changing behavior, and deceleration behavior during the lane changing process were analyzed. It is shown that the VMS recognition procedure can be classified as the multi-tasking driving behavior, because drivers have to complete VMS recognition, route diversion decision, deceleration and lane changing in a short time; if the VMS frontal distance is not long enough, drivers should turn the steering wheel quickly and sharply so as to change lanes continuously and urgently; to successfully enter the deceleration lane, some drivers reduce speed during the lane changing process, which increases the traffic risk; when the VMS frontal distance is too long, the short-term memory effect on VMS increases the driving load of drivers. © 2022, Editorial Department of Journal of Tongji University.
