The Influence Mechanism of Edge Rate Lines Width on Deceleration Effect

To explore the influence of the width of road edge rate lines on driver’s deceleration behavior, experiments were carried out on a straight section of an expressway. The findings show that the increase of the width of road edge rate lines can significantly enhance the deceleration effect. By introducing the concept of time frequency in the field of computer vision and analyzing a structural equation model, it is found that the edge rate lines width affects the driver’s deceleration behavior from two perspectives: the perceived speed danger and the perceived lane reduction. The width of edge lines and time frequency, initial vehicle speed, and vehicle width affect the deceleration of drivers synergistically. Finally, through the change of light flow expansion rate in driver’s eyes caused by marking and the time change of driver’s eyes crossing marking, the mechanism of speed perception danger and lane reduction affecting deceleration behavior is explained.
