Embodiment Construction

[0062] see figure 1 ~ Fig. 6, this embodiment provides a kind of implementation method of the speed feedback sign system of the warning of the safety state of the curve steering vehicle speed, and installs the monitoring camera 8, the rain sensor 9 and the side of the road subgrade before the entrance of the curve in the reverse direction A speed feedback marking system composed of a speed feedback marking device 14, wherein the speed feedback marking device 14 is composed of a central control chip 12, a speed measuring radar 11, an LED display screen 10 and prompt characters 13. The monitoring camera 8, the rain sensor 9 and the speed feedback marking device 14 share a circuit, and the lines communicate to transmit pulse signals.

[0063] 1) Parameter input: enter the road structure index information such as the flat curve radius, longitudinal gradient, ramp length and road surface structure depth of the curved road section where the speed feedback sign system is installed in...

Abstract

The invention discloses an implementation method for a speed feedback sign for bend steering vehicle speed safety state prewarning. The speed feedback sign system which consists of a monitoring camera, a rain sensor and a speed feedback sign device is arranged on the roadbed side of a road in front of a bend entrance in a retrograde vehicle direction, wherein a central control chip, a speed measuring radar, a light emitting diode (LED) display screen and prompting characters are arranged in the speed feedback sign device; a driver is warned to control the vehicle speed within a proper range before a vehicle enters a bend according to the conditions such as types of driven vehicles, weather conditions and road alignment conditions, so that traffic accidents after the vehicle enters the bend are prevented, and bend entrance critical safe vehicle speed corresponding to different vehicle types can be prompted in real time aiming at the change of road adhesion coefficients caused by different weather conditions and different bend road sections, and vehicle speed information and running states are fed back to the driver before the vehicle enters the bend; and therefore, enough time for the driver to adjust the vehicle speed is ensured and the road operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle-road coordination, in particular to a method for realizing a speed feedback sign system for early warning of vehicle speed safety state in curve steering. Background technique [0002] With the rapid development of road traffic in our country, the rapid increase of road traffic accidents has become a serious problem faced by traffic management. Although my country's relevant management departments have taken many measures in recent years, compared with western developed countries, my country's road traffic accident rate and accident indicators such as the death rate per 10,000 vehicles are relatively high, and the road traffic safety situation is still very severe. According to the statistical analysis of road traffic accidents, it is shown that the curved road section is an area with frequent traffic accidents. Drivers often cause traffic accidents due to speeding and entering the bend, resulting...
