Lane guide device at entrance section of signalized intersection

Abstract

The invention provides a lane guide device for an entrance section of a signal intersection. The lane guide device comprises guide arrows and lane separating lines, wherein the guide arrows and the lane separating lines are respectively made of a retroreflection material; the colors of the guide arrows in different driving directions are different; the lane separating lines comprise prompting sections, warning sections and solid line sections; the prompting sections are dotted line sections in front of the entrance section, and the colors of the prompting sections are the same with the colors of the guide arrows; the solid line sections are solid line parts of the entrance section, and are white; the warning sections are positioned between the prompting sections and the solid line sections, and are solid lines with warning color; a lane guide signboard is arranged above the road before entering the entrance section, and is made of the same material with the guide arrows and the lane separating lines. The lane guide device has the advantages that traffic information of the corresponding lane direction is provided for a driver in advance, the monotonicity of the road environment is decreased by the different color environments, the violated lane changing probability of vehicles at the entrance section is decreased, and the normal traffic order is maintained.

Description

technical field [0001] The invention belongs to the field of traffic design, in particular to a lane guiding device at the entrance section of a signalized intersection. Background technique [0002] Urban road signal intersection is an important node of urban roads, and it is often the bottleneck of road traffic capacity. The flow of people, various motor vehicles and non-motor vehicles gather together, resulting in complicated traffic conditions, many conflict points, and chaotic order. Frequent traffic accidents. According to the statistical analysis of accidents, the bad driving behaviors of drivers at the entrance of signalized intersections, such as driving on the line, illegally changing lanes, forcibly changing lanes, frequently changing lanes, illegally occupying lanes, and using wrong lights, etc. major potential cause of accidents. Among them, the bad lane-changing behavior of vehicles at the entrance section will affect the normal driving of surrounding vehicle...

AI Technical Summary

Problems solved by technology

This method does not prevent problems before they happen. Drivers on familiar roads may know that there are electronic eyes, directions of each lane, etc., but drivers on unfamiliar roads tend to ignore these and then cause illegal driving behaviors; It feels that the driver is not allowed to determine the target lane he wants to drive into in advance to complete the lane change behavior, thereby reducing the probability of this problem occurring

At present, there are few patented technologies in this area, and there is no systematic design description.
