What do lateral deceleration and longitudinal deceleration mean?
1 Answers
Lateral deceleration refers to the commonly known speed bumps, while longitudinal deceleration creates a visual impression of narrowing lanes for drivers, achieving the effect of reminding them to slow down. Here is more relevant information: 1. Lateral deceleration markings: These are white dashed lines set up in toll plaza areas, exit ramps, or other sections where vehicle speed reduction is required. They come in forms of single, double, or triple dashed lines, perpendicular to the direction of travel. Lane lateral deceleration markings consist of a set of parallel white dashed lines, serving to alert drivers to slow down. 2. Longitudinal deceleration markings: These are a set of diamond-shaped dashed lines parallel to the lane dividers. At the starting point of the longitudinal deceleration markings, a 30-meter transition section is set up, where the diamond-shaped dashed lines gradually widen from 10 cm to 30 cm. This is one of the newly added markings in the national standard for road traffic markings.
