Problems solved by technology

The current regulations on the passage of vehicles with yellow light signals do not consider that when the vehicle is driving close to the stop line, the signal light suddenly jumps to yellow light, and then it cannot brake safely behind the stop line, which is unscientific and not humane enough of

Embodiment Construction

[0074] The purpose of the invention of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the embodiments cannot be repeated here one by one, but the implementation of the present invention is not therefore limited to the following embodiments.

[0075] In this embodiment, it is assumed that there are three lanes in one direction at an entrance road at a level intersection in a certain city, and the limited speed at the intersection is v 0 =36km / h, road surface friction coefficient μ=0.75, left turn radius is R 1 =25m, right turning radius R 2 = 10m. Driver's reaction time t 0 = 1.3s, the braking force increases stage t 1 = 0.3s, there are 9 vehicles in the limited area when the yellow light is turned on, such as figure 1 , 2 shown.

[0076] A method for safe driving control of yellow light signals at intersections based on wireless technology, comprising steps:

[0077] Step S1: At...

Abstract

The invention discloses a safety driving control method through yellow light signal on an intersection based on a wireless technology. The method comprises the following steps: step 1, detecting the current velocity v of a car and the distance S (v) to a parking line; step 2, transmitting the collected data to a database of a center control computer; step 3, calculating the required distance S, within which the car completely stops at the current velocity v; step 4, generating a corresponding command according to the comparison result of S and S (v); step 5, adjusting the time ty<0> of a yellow light; step 6, transmitting the corresponding command to a vehicle-mounted terminal or a mobile terminal of the corresponding car; step 7, broadcasting driving tips by the vehicle-mounted terminal or the mobile terminal after receiving the command. According to the safety driving control method through the yellow light signal on the intersection based on the wireless technology, an intelligent active reminding technology is adopted to provide timely, accurate and enough guidance information for drivers, safe and efficient transit capacity is realized when the yellow light is turned on, fast, comfortable and safe road efficiency is completely played, and the safety driving control method is suitably popularized and applied to Internet of Vehicles in future.

Description

technical field [0001] The invention relates to wireless communication and traffic signal control technology, in particular to a method for safe driving control of yellow light signals at intersections based on wireless technology. Background technique [0002] The "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates that at signal-controlled intersections, "when the yellow light is on, vehicles that have crossed the stop line can continue to pass." It means that when the yellow light is on, it means that the traffic in the direction The right of way is about to end and the red light is about to come on. The yellow light signal is a warning signal for the replacement of the right of way at the intersection, and it is a transitional control step in the intersection signal control scheme. Its purpose is to ensure that it can safely switch from one signal phase to another, so that vehicles that are far away from the s...
