Method for setting double-row road surface speed control edge lines for controlling vehicle speed

Abstract

The invention provides a method for setting double-row road surface speed control edge lines for controlling the vehicle speed. The method comprises the following steps that 1) the inner side of a lane cutting line is provided with speed control edge wires, and materials adopt hot melt type quick dry yellow pavement anti-slip paint, wherein ingredients in the paint has the weight ratio that hot melting kettles: granular calcium carbonate: calcium carbonate ultrafine micropowder: water-based paint quick dry agents is 300:10:5:6, and the hot melting kettle comprises the following ingredients in percentage by weight: 45 percent of acrylic resin, 20 percent of aggregate, 10 percent of plasticizers, 15 percent of pigment and 10 percent of fillings; and 2) the control speed edge lines are alternate by one dotted line and one full line and are in arrangement parallel to the lane cutting line, the length of the single speed control edge line is 0.4 to 2m, and the distance between the adjacent speed control edge lines is equal to the length of the speed control edge line. Through the arrangement of speed control edge lines, the optical flow rate and the edge rate of the visual perception of a driver are changed, the perception speed of the driver is accelerated, and the subjective acceleration consciousness is reduced, so the goal of speed limitation is reached.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to a method for setting a double-row road surface speed control edge line to control the speed of a vehicle starting from the driver's speed perception. Background technique [0002] Domestic statistical results on the causes of road traffic accidents are: 80%-85% of road traffic accidents are caused by drivers, 5%-10% of road traffic accidents are caused by road factors, and only 10% of road traffic accidents are caused by drivers. Even lower road traffic accidents are caused by vehicle factors. While the driver is driving, 80%-90% of the information is obtained by vision. [0003] At present, the optical flow rate and edge rate among the visual factors that affect the driver's speed perception have received extensive attention, and scholars at home and abroad have done some related research on this. Among them: Denton's (1980) application of deceleration at ro...

Problems solved by technology

Theoretically, the greater the edge rate, the greater the driver's speed perception. However, due to the limit of the driver's visual system's ability to distinguish time, generally after the edge rate and optical flow rate reach 20-55Hz, the flash fusion phenomenon will occur, that is, street flash fusion. The appearance of the frequency makes the subjects underestimate the speed of the vehicle
