What are the standards for road marking?

The standards for road marking mainly include the following aspects:
One: Underline Type Selection
Road marking types include lane lines, stop lines, and zebra crossings, among others. When selecting the type of road marking, factors such as the actual use of the road, traffic volume, and driving speed should be considered.
Section II: Line and Color Specifications
Road marking should adhere to the prescribed line types and colors. Generally, lane lines are either solid or dashed, used to differentiate areas by direction and function. The stop line is a prominent red, indicating where vehicles must stop. Zebra crossings are white transverse lines, ensuring pedestrian safety. Additionally, special roads such as highways or transportation hubs may have unique line types and color requirements.
Section III: Width and Spacing Standards
The width and spacing of road markings should comply with industry standards. The widths may vary for different types of lines, for instance, lane lines are typically narrower, while stop lines might be wider to catch the driver's attention. Additionally, the intervals between the markings are determined based on road design and traffic flow to ensure that drivers can clearly identify and understand road signs.
IV. Construction and Maintenance Requirements
Road marking construction and maintenance are also part of the standards. During construction, ensure lines are clear and continuous, avoiding any blurring or breaks. Additionally, the choice of marking materials should consider factors such as road usage frequency, climate conditions, and vehicle pressure. In terms of maintenance, regularly inspect the condition of road markings, promptly repair any damaged sections, and ensure the effectiveness of road markings.
Overall, road marking standards encompass the selection of marking types, specifications for line patterns and colors, width and spacing requirements, as well as construction and maintenance criteria. The implementation of these standards contributes to regulating traffic behavior, enhancing road traffic efficiency, and ensuring the safety of pedestrians and drivers.
