Cross passages are critical infrastructure for evacuation and rescue in fire accidents of road tunnels. Reasonable cross channel design is conducive to improving the efficiency of evacuation and rescue. In this paper, a key parameter setting method of highway tunnel cross-passages based on risk assessment is established. Aiming for safe evacuation of people and vehicles in the tunnel, this method is based on risk evaluation and involves comprehensive analysis of the effects of tunnel properties, traffic conditions, cross passage parameters and evacuation guidance measures so as to support the development of an optimum design of cross passages. This paper describes in detail its design approach, parameter determination process and risk evaluation method and taking an actual tunnel as example, demonstrates the process of determining key parameters of tunnel cross passages on the basis of risk evaluation.
