Bicycle priority roundabout sight guidance system

Abstract

The invention relates to the technical field of traffic safety of roundabout, in particular to a bicycle priority roundabout sight guidance system. Raised road signs, safety islands, bicycle lane reminding signs and yellow flashing lights are arranged on motor vehicle conflict sections, the safety islands are arranged at two sides of bicycle lanes in pedestrian conflict sections, and multiple types of warning columns are arranged on the safety islands, pedestrian reminding signs and way directing signs are arranged in the outer sides of the bicycle lanes, intersection reminding signs are arranged in the diversion sections, reflective signs are arranged on the confluence sections and the annular sections, and the bicycle lanes are made of colored asphalt, so that the multicolor bicycle lanes are formed. The safety and comfort of riders are improved, and the direction perception and lane keeping capacity of the riders at the annular intersection are improved, the visual area of the rider is compressed, the effects of smoothing visual transition between a conflict area and a non-conflict area and decomposing and simplifying a riding task are achieved, meanwhile, the alertness of the motor vehicle drivers is improved, the effect of providing enough strain time is achieved, and then the traffic safety of the bicycle lanes at the roundabout is guaranteed.

Description

technical field [0001] The invention relates to the technical field of traffic safety at roundabouts, in particular to a bicycle-first sight-guiding system for roundabouts. Background technique [0002] For roundabout intersections, there are generally no crossing facilities specially set up for bicycles at intersections, and the right of way for bicycles is unclear and discontinuous, which makes bicycles choose to cross the street with pedestrians or motor vehicles. However, the speed of bicycles is faster than that of pedestrians and slower than that of motor vehicles. When bicycles and pedestrians are mixed, due to the obvious speed difference, it will cause inconvenience to ride and easily scratch pedestrians. At the same time, the faster speed of bicycles is also easy for motor vehicle drivers Misjudgment of speed occurs, resulting in traffic accidents. When bicycles and motor vehicles are mixed, cyclists will face greater danger, and when the traffic volume is large, ...

AI Technical Summary

Problems solved by technology

However, the speed of bicycles is faster than that of pedestrians and slower than that of motor vehicles. When bicycles and pedestrians are mixed, due to the obvious speed difference, it will cause inconvenience to ride and easily scratch pedestrians. At the same time, the faster speed of bicycles is also easy for motor vehicle drivers Speed ​​misjudgment, resulting in traffic accidents

When bicycles and motor vehicles mix, cyclists will face greater danger, and when the traffic volume is large, it is easy to cause confusion and congestion

Moreover, cyclists are prone to visual dizziness at the roundabout, making it difficult to judge the exit position

In the existing research, the research on bicycle lanes mainly focuses on ordinary bicycle lanes, while there are few related studies on bicycles at roundabouts
