Highway maintenance is a difficult task that the municipal government has been insisting on doing better. This is actually a very complicated and demanding task. It involves a lot of professional knowledge. Then we know how many road maintenance terminology we use. ?
The term “conservation of road maintenance operation control zone†means a traffic management zone for highway maintenance and repair operations. It is divided into six areas: warning, upstream transition, buffer, work, downstream transition, and termination. We now explain them in order. The warning area is the section from the starting point of the operation control zone to the construction of the upstream transition zone. The minimum length of the warning zone and the correct setting of the speed limit sign are crucial to the improvement and improvement of the safety level of highway maintenance operations. The upstream transition zone refers to the area that ensures the smooth transition of the vehicle from the upstream of the closed lane to the non-closed lane next to the buffer zone. The meanings of the buffer zone and the work zone are better understood. They respectively refer to the construction operation area for maintenance of the road maintenance work area and the area for ensuring the smooth transition of the vehicle from the lane next to the work zone to the normal lane. Termination area refers to a road section that is set in the downstream of the work area to adjust the state of the vehicle. Temporary road markings are traffic markings that are temporarily assigned to meet the safety needs of maintenance and repair operations.
In addition to the above mentioned technical terms for the region, we also need to understand what the symbols mean. S - length of warning zone; LJ - shoulder closed the length of the upstream transition zone; G - length of the working area; W - width of the closed lane; H - length of the buffer; LS - lane closure of the upstream transition zone length and so on this series of professional terms. Originally you may think that these letters are indistinguishable. Do you understand the meaning behind them?
There are also some professional terms we all know, because this often appears in our lives, such as sidewalks, also known as "crosswalks", refers to the use of zebra crossing and other markings to mark the passage of pedestrians across the lane, as well as the community often appear The speed bump, as its name implies, is a seat belt for vehicle deceleration. Speed ​​reduction belts have been widely used in roads around the world, which can increase the safety of traffic crossings and greatly reduce the accidents at various traffic crossings. The material is mainly rubber and metal.
