What are the main signs of traffic signs?

Main signs:

(1) Warning signs: signs that warn vehicles and pedestrians to pay attention to dangerous locations ahead of the road.

(2) Prohibition signs: signs that prohibit or restrict a traffic behavior of vehicles and pedestrians.

(3) Instruction signs: signs indicating the movement of vehicles and pedestrians.

(4) Guide signs: signs that convey road direction, location, and distance information.

(5) Tourist area signs: Provide signs indicating the direction and distance of tourist attractions.

(6) Road construction safety signs: signs announcing the passage of road construction areas.

(7) Speed ??limit sign: A sign warning vehicles to slow down.

Introduction:

Traffic signs are road facilities that use words or symbols to convey guidance, restrictions, warnings or instructions. Also known as road signs and road traffic signs. Traffic signs generally focus on safety. Setting eye-catching, clear and bright traffic signs is an important measure to implement traffic management and ensure safe and smooth road traffic.

There are many types of traffic signs, which can be distinguished in various ways: main signs and auxiliary signs; movable signs and fixed signs; illuminated signs, luminous signs and reflective signs; and reflecting changes in the driving environment. variable information flag.

Structural design:

1. The design basic wind speed should be based on the local flat open ground, 10m high from the ground, with a recurrence period of 50 years, 10min average maximum wind speed, and not less than 22m /s.

2. The traffic sign structure should be designed according to the limit state of bearing capacity and the limit state of normal use, and should meet both structural and process requirements.

3. The structural importance coefficient of traffic signs can be divided into two levels:

(1) Cantilevered and gantry-type traffic signs located on highways and first-class highways 7 , the structural importance coefficient.

(2) For other types of traffic signs located on expressways, first-class highways and traffic signs located on other grade highways, the structural importance coefficient Y=0.9.

4. The load calculation and combination of the traffic sign structure, the limit state design method, and the design of the foundation foundation should comply with the current "General Specifications for the Design of Highway Bridges and Culverts" (JTC D60) and "Design Specifications for Foundations and Foundations of Highway Bridges and Culverts" "(JTJ 024), "Steel Structure Design Code" (JB 50017) and "Road Traffic Signs and Markings" (JB 5768), etc.
