Road marking plays a very important role in channelization, traffic separation and diversion of traffic flow. At the same time, it also has the effect of beautifying the road. Therefore, the design, construction and other quality problems of road marking reflect its impact on traffic safety. The impact of traffic facilities road marking on traffic safety mainly includes the following four aspects: (1) when the accuracy of marking setting out is not enough, the vehicles driving in separate lanes may have side collision（ 2) When the marking edge is not uniform, the thickness is not uniform, there are bubbles, rough edge cracking, it will affect the clarity of the reflective marking at night（ 3) When the quality and quantity of glass beads are not up to the requirements

Benwangxun (reporter Li Ye, correspondent Jiao Xuan and Liu Yuan) scientific, standardized and reasonable road traffic channelization is the basis of guiding and standardizing the safe travel of traffic participants, the yardstick of measuring the management level, and can more intuitively display the image of the city. In the near future, the traffic management department will continue to carry out research in the square area behind Tianjin railway station, improve the channelization of road traffic along Huabi Road, and add many new traffic signs and markings. Huabi road is located in the square area behind Tianjin railway station, where pedestrians, motor vehicles and non motor vehicles are intertwined, and the traffic situation is complex. Taxis and pick-up vehicles will lead to traffic jams if they occupy the road and wait for a long time along Huabi road

The main structural forms of guardrail are semi-rigid guardrail, rigid guardrail and flexible guardrail. Each form has its own adaptability. At present, semi-rigid guardrail is widely used. Corrugated beam guardrail is a common form of semi-rigid guardrail. It has a certain degree of stiffness and toughness. It mainly absorbs collision energy through the deformation of beam, column and soil foundation. The damaged parts are easy to replace, and has a certain line of sight guidance. The corrugated beam guardrail is composed of corrugated guardrail plate, column, bracket, anti blocking block, end, fastener and foundation. Concrete guardrail is a kind of wall type guardrail structure with certain section shape, which belongs to rigid guardrail. Concrete protection

What is the violation of the prohibition mark? 2020-02-07 09:45:00

Violation of prohibition marking refers to: prohibition marking refers to the yellow solid line on the ground (no crossing in the middle of the road) and the yellow big fork (representing no parking), and pressing it up means violation of prohibition marking. Common situations: 1. Single and double yellow solid lines are prohibited markings, and it is illegal to press or cross the line during driving. 2. If the intersection does not drive in the corresponding lane according to the guide line, it also belongs to the above provisions. 3. Illegal temporary or long-term parking. 4. Turning around is not allowed on the road section, and turning left is prohibited, all of which are in violation of the prohibition marking instructions. Note: Prohibition of marking is a violation of the

　　The structure of guardrail mainly includes semi-rigid guardrail, rigid guardrail and flexible guardrail. Each form has its adaptability. At present, semi-rigid guardrail is widely used. Wave beam guardrail is a common form of semi-rigid guardrail, which has certain rigidity and toughness. It mainly absorbs collision energy through the deformation of beam, column and soil foundation, and the damaged parts are easy to replace and have certain visual guidance function. The wave beam guardrail is composed of corrugated guardrail board, column, bracket, anti blocking block, end, fastener and foundation, etc.

Concrete guardrail is a kind of wall guardrail structure with certain section shape, which belongs to rigid guardrail. The concrete guardrail shall be made of cement, sand, water and steel bars. The concrete guardrail formwork is an indispensable and important tool in the process of prefabrication, which directly affects the quality of the precast concrete, and it needs to check the size and quality of the steel formwork. The quality of concrete base affects the quality after installation, and the quality of base course shall be tested according to the specifications. The appearance quality and geometric dimension of concrete guardrail shall also be tested. Cable guardrail is a flexible guardrail made of steel wire rope. According to the location, it can be divided into two types: Road side and central separation zone, and from the burying conditions, it can be divided into two types: buried in the road and in concrete. Where the column cannot be driven and the subgrade fill cannot guarantee the depth of the column, concrete foundation shall be used. The cable is made of 3 × 7 galvanized / right screwed structure with high strength and excellent corrosion resistance. The cable guardrail is composed of end column, middle end column, intermediate column, bracket, cable anchor and fastener, and it is required to conduct surface anti-corrosion treatment. The quality of cable guardrail shall include anti-corrosion performance, material performance, geometric dimension and appearance quality.
