Speed ​​limit Signs Make People Run Safely

The minimum speed limit sign indicates the minimum speed limit for a motor vehicle to enter the road ahead. This sign is set at the starting point of a speed limit section of a highway or other road. This is the minimum speed limit sign, indicating the minimum speed limit for a motor vehicle to enter the road ahead. It is required that the minimum speed of the motor vehicle should not be less than 50 kilometers per hour when the road conditions ahead are good. It is set at the starting point of the speed limit section of the expressway or other roads. And the appropriate positions behind the overpass intersections.

This sign and the maximum speed limit sign are set together on the same sign pole instead of being set separately. When installed on the roadside, the maximum speed limit sign is at the top and the minimum speed limit sign is at the bottom. The sign on the left indicates that the minimum speed limit is 50 kilometers per hour. Hour. This is the minimum speed limit sign on the sign, and there is also a minimum speed limit sign marked on the road.

The setting of speed limit signs in my country is mainly based on the speed limit of different road sections. For general road sections with good road alignment, the speed limit value is determined according to the operating speed; while other road sections are set according to the traffic conditions or according to the situation of road traffic accidents. set up. The setting of the speed limit sign mainly has the problems of the speed limit value and the speed limit position:

(1) The problem of speed limit value: If the entire highway has a single speed limit according to the design speed, and the speed limit is too low, it will not be able to meet the actual conditions and the needs of safe operating speeds, resulting in reduced traffic efficiency and waste of resources.

(2) Setting of speed limit signs for special road sections: There are no different speed limit signs for speed limit on up and down slopes, road sections with increased traffic flow at intersections, and speed limit on roads with many bends.

(3) Speed limit setting on accident-prone sections: The size of the speed limit and the length of the speed limit distance, as well as where the speed limit starts and where the speed limit is lifted, do not have a scientific and reasonable theoretical analysis. Some only set "accident-prone sections, "Slow down" sign only.
