Embodiment Construction
[0033] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0034] Based on the principles of cognitive psychology and ergonomics, the present invention determines the continuous setting method of speed limit signs for different vehicle types on road sections prone to accidents in mountainous areas, so as to scientifically and rationally guide drivers before entering road sections prone to serious accidents in mountainous areas. Deceleration control and prompts, such as figure 1 As shown, a detailed description can refer to the Summary of the Invention.
[0035] By collecting the basic data of a highway accident-prone road section, the mileage stake number of the starting point of the mountainous road accident-prone road section is K10+200, and the sharp curve radius of the road section is 100 meters, and the lateral slope of the road surface is 7%. Before entering the accident-prone road section, use the traffic spe...
