Road marking

Road marking is an important part of traffic engineering, and its purposes are mainly reflected in the following aspects:

Guiding traffic flow

- Regulating vehicle driving: By setting lane lines, different lanes are clearly demarcated to indicate that vehicles should travel in their respective lanes, enabling vehicles to drive in the specified directions and along the specified trajectories. For example, on expressways, the combination of white solid lines and dashed lines can guide vehicles to drive in an orderly manner, reducing traffic chaos and intersection conflicts.

- Guiding the driving direction: In complex traffic areas such as intersections, markings like guiding arrows clearly indicate the directions for vehicles to turn, go straight, or make a U-turn, helping drivers plan their driving routes in advance and improving traffic flow efficiency.

Ensuring traffic safety

- Separating different traffic participants: Road markings can separate motor vehicles, non-motor vehicles, and pedestrians. For example, white solid lines are used to separate motor vehicle lanes from non-motor vehicle lanes, and zebra crossings are used to demarcate pedestrian crossing areas, reducing mutual interference and reducing the risk of accidents.

- Warning of dangerous areas: On dangerous sections such as sharp turns, steep slopes, and tunnel entrances, warning markings such as yellow solid lines are set up to remind drivers to drive carefully and take measures such as slowing down in advance.

Improving traffic management efficiency

- Facilitating traffic law enforcement: Clear road markings provide a clear basis for traffic law enforcement, making it easier for law enforcement officers to determine whether vehicles violate regulations, such as crossing solid lines or running red lights, thus ensuring the effective implementation of traffic laws and regulations.

- Optimizing traffic organization: Traffic management departments can change the functions of lanes or traffic flow directions by adjusting the markings according to traffic volume and demand, achieving a reasonable allocation of traffic resources. For example, tidal lanes are set up to improve the utilization rate of roads.

Providing traffic information

- Marking special areas: Markings are used to identify special lanes such as bus-only lanes and emergency lanes, clarifying their usage rules and scopes, and ensuring the priority passage rights of special vehicles.

- Assisting in navigation: Road markings, in conjunction with traffic signs, can provide drivers with more comprehensive navigation information, such as distance prompt lines and exit advance warning lines, helping drivers better understand the traffic conditions and driving directions.
