Abstract: In the current operation of the entire highway project, the ramp area is the area with the highest accident rate and the most serious area. Restricted by factors such as terrain and cost, how to realize the rationalization of the linear design of the expressway becomes the key under the premise of ensuring driving safety. Based on a comprehensive understanding of the ramp types and their characteristics, this article analyzes several common ramp linear combinations and, in conjunction with specific cases, proposes corresponding optimization design schemes aimed at reducing accident rates and providing more comfortable and safe vehicles. surroundings.
