Description

Intersection right-turning passing system

Technical Field

The invention relates to the technical field of intersection traffic management, in particular to an intersection right-turning passing system.

Background

The motor vehicles are rarely limited by signal lamps when turning right at the intersection, and are easy to form conflict with pedestrians and non-motor vehicles which go straight, and according to incomplete statistics, the traffic accidents caused by the motor vehicles turning right account for 1/8 of the total number of traffic accident cases. The intersection is an area where various traffic flows are interlaced, and is also a centralized waiting area for pedestrians and non-motor vehicles, conflict points are more, and the motor vehicles have a visual field blind area and an inner wheel difference when turning on the right, so that the probability of accidents is higher. The visual field blind areas comprise an A-column visual field blind area and a right rearview mirror visual field blind area, as shown in figure 1, partial visual fields observed by a driver through the front windshield and the front window can be shielded by the A columns positioned on two sides of the front windshield to cause the A-column visual field blind area, through calculation, the A-column visual field blind area is about 15.77 degrees (as shown in a C area in figure 1), the blind area also exists in the visual field observed by the driver through the rearview mirror outside the vehicle, the right rearview mirror visual field blind area is about 70.54 degrees (as shown in a area in figure 1), even if some vehicles are additionally provided with a convex blind spot mirror on the rearview mirror, the blind area still exists. The inner wheel difference is generated when the vehicle turns, the motion tracks of the front wheel and the rear wheel are not on the same arc line, the difference between the turning radius of the front inner wheel and the turning radius of the rear inner wheel is the inner wheel difference, the common small-sized vehicle can generate the inner wheel difference close to 1 m to the maximum extent, the larger the vehicle body is, the more the steering wheel is beated, the larger the formed inner wheel difference is, and some large-sized vehicles can generate the inner wheel difference of more than 2 m. Some pedestrians or non-motor vehicles are located in the inner wheel difference area of the turning vehicle, the front wheels of the turning vehicle are avoided, the driver can see the pedestrians or the non-motor vehicles, danger cannot occur, the areas are not known to be the sight blind areas of the driver, the pedestrians or the non-motor vehicles can be collided or rolled by the vehicle when the pedestrians or the non-motor vehicles continue to stay in the areas, and the areas are really dead zones.

The general view in the society at present is that the motor vehicle can not solve the problem of the right side view blind area through the technical means, and the reason of traffic accidents caused by the right turning of the motor vehicle is that firstly, the driver negligibly neglects subjectively and the pre-judgment on the right turning road condition is insufficient; and secondly, pedestrians and non-motor vehicle personnel have the problem of getting on the road, expose themselves in high-risk areas of the intersection, subjectively push the responsibility of intersection traffic safety and the initiative of avoiding danger to the motor vehicle drivers, and are completely unaware of the existence of visual field blind areas of the drivers. Therefore, when the potential traffic safety hazards of the intersection are treated, propaganda and education are mainly used, safety awareness and safety knowledge of drivers, pedestrians and non-motor vehicle personnel are expected to be improved, mutual concierge is promoted, but the traffic efficiency of the intersection is greatly reduced, and the effect is not large from the statistical data of traffic accidents caused by the fact that the motor vehicles turn right in recent years.

Disclosure of Invention

The invention aims to solve the technical problem of designing a right-turning passing system of an intersection, which can practically avoid the conflict between motor vehicles and pedestrians and non-motor vehicles when the motor vehicles turn right and can also improve the passing efficiency of the intersection.

The technical proposal of the invention is to provide a right-turn traffic system at an intersection, which comprises mutually crossed roads, wherein each road is provided with a motor vehicle lane entering the intersection, a motor vehicle lane leaving the intersection and a pedestrian crossing, and both sides of the road are provided with non-motor vehicle lanes, the rightmost lane in the motor vehicle lanes entering the intersection is set as a right-turn lane or a straight lane and a right-turn lane, a right-turn danger warning area is arranged between any two adjacent roads, both ends of the right-turn danger warning area are respectively connected with pedestrian crosswalks on the two adjacent roads, and are respectively opposite to the edge lines of the lanes on the two adjacent roads, an anti-collision device is arranged in the right-turn danger warning area, the anti-collision device is used for isolating the left area and the right area of the right-turn danger warning area, and the right area of the right-turn danger warning area is connected with the non-motor vehicle lanes on the two adjacent roads.

Compared with the prior art, the right-turn passing system for the intersection has the following advantages: after the non-motor vehicles and the motor vehicles turning right exit the respective lanes, the non-motor vehicles and the motor vehicles turning right enter the intersection without lane division, the right-turn danger warning area can warn the motor vehicles to pass through the left area of the right-turn danger warning area, and warn the non-motor vehicles to pass through the right area of the right-turn danger warning area; the left area and the right area of the right turn dangerous warning area are isolated by an anti-collision device, a motor vehicle turning right can enter a motor vehicle lane of an adjacent road only through the left area of the right turn dangerous warning area, a non-motor vehicle turning right can enter a non-motor vehicle lane of the adjacent road only through the right area of the right turn dangerous warning area, a straight non-motor vehicle can reach a crosswalk of the adjacent road only through the right area of the right turn dangerous warning area and then cross the crosswalk across the intersection, the non-motor vehicle turning left can only realize turning left through one crosswalk and two vertical crosswalks in a mode of 'two-time crossing', the right turn dangerous warning area and the anti-collision device arranged in the right turn dangerous warning area can prevent the motor vehicle and the non-motor vehicle from mixing, so that the motor vehicle and the non-motor vehicle can not enter a blind area of a driver, and conflict with the motor vehicle and the motor vehicle when turning right can be avoided, and after the anti-collision device is used for isolation, the probability of avoiding pedestrians and non-motor vehicles when the motor vehicles turn right is low, and the passing efficiency of the intersection can be improved. Compared with the situation that an isolation island or a right-turn special lane is arranged at the intersection, the right-turn danger warning area is small in occupied space, low in road surface reconstruction cost and suitable for the intersection passing through any multiple lanes. Compared with an isolation pile, the anti-collision device does not prevent collision and is easy to be collided by a motor vehicle, and the anti-collision device can effectively prevent the mixed behavior of the motor vehicle and the non-motor vehicle caused by the difference of the wheels in the motor vehicle.
