Traffic Marking Design Principles: a. Traffic Marking Colors: Except for the centerline of two-way two-lane roads, no-overtaking lines, and mesh lines which use yellow lines, all other markings are white. b. Traffic Marking Width: Longitudinal markings (lane dividing lines, guided lane lines, lane edge lines, etc.) have a line width of 15cm; bus-only lanes and intersection bus guide lane markings have a line width of 30cm; diversion lines at merging and diverging areas have a line width of 45cm; transverse markings are calculated based on the perspective projection principle under dynamic conditions, with yield line width of 20cm and pedestrian crossing width of 40cm. c. Determination of the dashed line interval length for traffic markings: The ratio of the solid segment to the interval length in traffic marking dashed lines is directly related to vehicle speed. To achieve the desired effect, for lane dividing lines where the design speed is ≤40km/h, the solid segment length is 2m and the interval length is 4m.

Drying time during construction: The coating dries within 3-5 minutes after application, allowing for quick traffic access and construction.
Traffic marking paint is typically white or yellow, used for daily traffic, delineating traffic areas, and serving as traffic signs. Naturally, this paint must adhere well to asphalt, stone, or concrete and withstand traffic and environmental impacts. Depending on the specific application, road markings are made from different materials. Simple markings, which are rarely run over by vehicles, often use synthetic paints. For markings requiring higher durability, hot spray and thermoplastic materials are used. To enhance the visibility of road markings at night, reflective beads are added during production.
Service life: Due to strong adhesion, thick film, acid and alkali resistance, and color fastness, the marking life can last up to three to five years under normal use conditions.

Construction projects for traffic markings, factory road markings, factory parking lots, underground garage markings, school road markings, residential area markings, etc., are divided into two types: cold paint marking and thermoplastic marking. Special cold paint for roads is used, applied manually with uniform thickness and clear color. This includes parking spaces, no-parking yellow zones, channel lines, diversion strips, and directional arrows.
