Traffic induction method for left turning at traffic intersection

Abstract

The invention discloses a traffic induction method for left turning at a traffic intersection. The traffic induction method comprises the steps of: calculating a minimum vehicle speed required for a vehicle to pass a specified intersection when the vehicle enters a specified region at the intersection according to the remaining time until a signal lamp is switched to a red light and a distance that the vehicle needs to drive to pass the intersection completely; comparing the minimum vehicle speed with a speed limit value at the intersection, and determining whether the vehicle can pass the traffic intersection before the red light is switched to in an ideal state; if not, prompting the vehicle to control the vehicle speed and drive to a stop line for waiting; and determining a passing coefficient of the vehicle passing through the intersection according to a distance between the vehicle and a front vehicle as well as a speed of the front vehicle if determining that the vehicle can passthe intersection in an ideal state, and making suggestions on whether a vehicle continues to drive according to the passing coefficient. The traffic induction method for left turning at the traffic intersection disclosed by the invention improves the safety of the left-turning vehicle passing through the intersection.

Description

technical field [0001] The invention belongs to the technical field of traffic guidance methods, in particular to a traffic guidance method for turning left at a traffic intersection. Background technique [0002] In today's society, cars have become an indispensable means of transportation in people's lives. Due to the increasing number of vehicles, traffic jams and traffic accidents occur from time to time. [0003] Setting signal lights at traffic intersections reduces the occurrence of traffic accidents to a certain extent. However, due to lack of driving experience or rushing of vehicles, etc., traffic jams often occur at traffic intersections, and traffic accidents are caused due to being eager to pass through intersections at too high a speed. Especially when traffic vehicles turn left, due to the long driving distance, there are often times when halfway through the journey, the red light is on, causing the left-turning vehicle to be in the middle of the road, which...

AI Technical Summary

Problems solved by technology

However, due to insufficient driving experience or rushing vehicles, etc., traffic jams often occur at traffic intersections, and traffic accidents are caused due to the excessive speed of vehicles rushing through intersections.

Especially when traffic vehicles turn left, due to the long driving distance, there are often times when halfway through the journey, the red light is on, causing the left-turning vehicle to be in the middle of the road, which affects the situation of straight-going vehicles. If many vehicles turn left Vehicles slowing down at intersections may cause traffic jams and even cause traffic accidents
