What is the center line demarcation for one-way traffic lanes?

[Carvalho]

One-way traffic lane demarcation center lines are traffic markings used to separate traffic flows moving in the same direction, typically consisting of white dashed/solid lines or yellow dashed/solid lines. Below are relevant details: 1. Road traffic markings: Traffic markings (Traffic Index Line) refer to identifiers on road surfaces that convey guidance, restrictions, warnings and other traffic information to road users through lines, arrows, text, vertical markings, raised pavement markers and contour markings. Their purpose is to regulate and guide traffic, and they can be used in conjunction with signs or independently. 2. Characteristics: Road traffic markings are primarily painted on road surfaces, enduring sun exposure, rain, snow, frost and vehicle impact abrasion, thus requiring strict performance standards. They must have short drying times and simple application procedures to minimize traffic disruption.
