The Hub Interchange is the most advanced node in the expressway network or the trunk-line functional road network system, and is responsible for the important function of traffic flow conversion between the expressway network and the trunk road network. With the continuous expansion of the city scale and the rapid construction of highways nationwide, the number of Hub Interchanges has been increasing, and the proportion of accidents at the exit of interchanges is relatively high. Traffic safety and traffic efficiency need to be further improved. Among the Hub Interchange exit signs system, the most important is the exit sign and the exit sign at the triangle end of the ramp. The 0 m exit sign mark as the reference point has the greatest influence on the driver. If the setting position is unreasonable, it is may lead to the driver not being able to smoothly enter the correct ramp exit. Based on the consideration of the driver’s visual characteristics and the traffic characteristics on the main line of the expressway, this paper selects the ramp diversion point as the new control point and establishes the vehicle exit ramp model. Estimate the front position of the 0 m exit sign mark in the case of the most harmful exit.
