- Abstract
- From an adjacent tunnel group characteristics, the paper analyzed traffic signs setting problems of adjacent tunnel group based on ergonomics and traffic flow theory. The paper analyzes the conditions of how the drivers to make effectively use of passed information from traffic signs. Based on analysis of the relationship among visual inertia, variety velocity of pupil area, theoretical models of how to effectively establish traffic signs was set up. The proposed model is tested in adjacent tunnel groups of Liuan-Wuhan expressway, and road safety, location, reasonable depression angle and exit distance of adjacent tunnel group traffic signs are calculated and analyzed. The model is verified its rationality. The results can provide theoretical guidance for how to set up exit traffic signs of the adjacent tunnel group scientifically.
