Speed Induced Design Based on Visual Characteristics for Highway Tunnel in Cold Region
摘要
In order to improve the driving safety of the freeway tunnel section, the research on zoning section speed limit is carried out. Based on the visual characteristics of tunnel drivers and its influence on traffic safety, this paper establishes the design system of speed limit section in tunnel, divides the speed limit section in tunnel, analyzes the acceptability of drivers to the speed limit setting by questionnaire method, and gives an example application. The design method can provide a basis for the design of speed limit in tunnel section.
