Road traffic marking construction project

Most of the marking lines in road traffic construction are set up in bustling road sections, intersections with large traffic flow of people and vehicles. The signs should be eye-catching, detailed, and specify the key information such as standard directions and distances. Be good at applying road markings, driving signs, text arrows Such signs constitute a complete and effective road safety system, so as to effectively guide the flow of vehicles and people, ensure traffic safety, and facilitate road construction.

The establishment of traffic engineering signs must adhere to two principles. One is the principle of reasonable setting.

The road width, people and traffic flow, vehicle speed, geology and other conditions of the construction road section are set and planned to ensure that the marking line is set reasonably, which is the key to the engineering road sectionparts, such as steep slopes and intersections, should have clear and detailed warning signs and marking lines to ensure that the flow of people and vehicles is reasonable and safe, and effectively prevent various road traffic accidents.

 

1. 1. Construction preparation
   2. 
      The design and setting of road traffic engineering signs and markings are directly related to traffic safety, so it is necessary to consider various factors that may easily lead to traffic accidents to ensure the rationality and scientificity of design and setting. In road traffic, the driver plays a leading role, and the number of pedestrians is dominant. Once an accident occurs, both are in a passive state.

   4. Therefore, when planning signs, it is necessary to fully consider the traffic flow and pedestrian flow of the engineering road section, and conduct scientific analysis and analysis of the time period changes of the flow. Forecast to determine logo design readiness. Taking vehicles as an example, as the main moving object in road traffic, the length, width and height of the car itself, its movement characteristics, intersections around the road, and its use can all be used as important standards for the design and setting of facilities and the formulation of driving safety indicators. and slope provide relevant guidance parameters for road follow-up capacity, safety, circulation, management work, etc. In addition, attention should be paid to possible pollution caused by road traffic, and consideration and prevention of noise pollution, exhaust gas pollution, and vibration pollution should be done to ensure that The design of traffic engineering signs and markings is the best.

      Road traffic signs use text, graphics, symbols, etc. to convey road safety information and vehicle information to pedestrians and drivers. It is an important way for the traffic department to implement road flow management and safety management. Construction safety signs, etc.,
   3. 
      The main reason is that drivers or pedestrians driving at high speed can receive road traffic information intuitively and quickly when the road traffic keeps running, so as to adjust the traffic plan in time. For example, vehicles on the road can safely, orderly and quickly complete the change and transfer of driving direction, realize lane change.
   4. 
      This is because various reminders about distance, direction, and location have given them correct guidance, but if signs are blocked, damaged, or lost, it will undoubtedly seriously affect the driving quality and safety. During the construction of traffic signs, attention should be paid to active communication and cooperation with the municipal and city appearance departments.
   5. 
      Negotiate the setting of road traffic signs and surrounding billboards, and try to avoid signs and signs of the same color within 50m of the sign, especially billboards that are easily confused with the color of the sign, such as blue and green; It is necessary to actively communicate with the municipal planning management department, and set up traffic signs in a reasonable, scientific and orderly manner as much as possible based on the current and later municipal road planning conditions; for the situation that trees are likely to block traffic signs around traffic signs, it is necessary to actively communicate with the municipal greening department Communicate, trim trees regularly and in a timely manner to avoid blocking road signs.
   6. 
      During the construction of traffic signs, it is necessary to consider the overall situation of the entire road section of the project as far as possible in the layout of signs to ensure that the setting of signs is unified, rational and continuous, and can provide drivers and pedestrians with complete and accurate road information, so that they can quickly grasp the surrounding roads situation, quickly reach the designated location. For the situation where there are too many road traffic signs on the same road section or too much information on the same location, if you want to set the signs, you can set them on the same pillar, and follow the order from top to bottom while avoiding the surrounding buildings, trees, and billboards. 
   7.  
   8. Set up according to the principle of first left and then right. In addition, during the setting process, it is necessary to avoid occupying the building boundary as much as possible to ensure that the clear height and width of the road surface meet the requirements. For example, the design of the warning sign at the entrance of the inner ring road in the city should set the name of the sign at the first exit and 1/2 position downstream of the entrance as close as possible, so as to ensure that pedestrians and drivers can quickly see the intersection sign after the exit ramp lands, ensuring traffic Safe and convenient traffic management.

   Line marking in road traffic is a complete traffic safety facility composed of various lines, road markings, raised road signs, text, etc., which guide pedestrians and drivers to drive in the correct direction, and play a role in diverting traffic flow and facilitating traffic safety management.

4. White hot-melt paint should be used for marking lines on higher-grade road surfaces. Adding glass beads to the paint can improve the reflective performance of marking lines, so that drivers can clearly see various marking lines when driving fast, especially Especially at all kinds of intersections and open sections of the middle belt, it is necessary to set up sidewalk horizontal lines, especially in areas with high traffic accidents, appropriate speed bumps should be set up to remind drivers to slow down in time to reduce traffic accidents. At night, outline markings should be set up to reflect car lights in time and guide drivers to drive safely at night.

6. The international regulation delineation mark is 50m. As far as the actual road traffic conditions in my country are concerned, the spacing is too large and the indication effect is poor. Therefore, the setting of domestic delineation marks mostly adheres to the data of 20-28m for the main line and 4-8m for the ramp of the main line, so that the delineation mark can be as large as possible. Maximize the value of ensuring road traffic safety.
