Description

Isolation pile

Technical Field

The utility model relates to a technical field of crossing traffic management equipment more exactly relates to an isolation stake.

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 positioned in the inner wheel difference area of the turning vehicle, so that 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 very known to be the blind areas of the driver, the pedestrians or the non-motor vehicles can continue to stay in the areas and can be collided or rolled by the vehicles, and the areas are really dead zones.

The reason that the traffic accident is caused by the right turning of the motor vehicle is that firstly, a driver is negligent subjectively and the pre-judgment on the road condition of the right turning is insufficient; and secondly, pedestrians and non-motor vehicle personnel have the problem of lane rescue, the pedestrians and the non-motor vehicle personnel are exposed in a high-risk area of the intersection, the responsibility of traffic safety of the intersection and the initiative of avoiding danger are both subjectively pushed to the motor vehicle driver, and the driver is completely unaware of the existence of a visual field blind area. When the traffic potential safety hazards of the intersections are treated, firstly, education is publicized, the safety awareness and safety common knowledge of drivers, pedestrians and non-motor vehicle personnel are improved, and mutual gifts are advocated; and secondly, the isolation piles are arranged to isolate the motor vehicles turning right from the pedestrians and the non-motor vehicles going straight. The isolation stake of prior art is the plastics material of integral type usually, adopts the bolt fastening on the road surface, and the driver often can predetermine not enoughly when turning right for the motor vehicle leads to the damaged fracture of isolation stake because the poor extrusion of interior wheel to the isolation stake, thereby must demolish old isolation stake, the isolation stake of renewal, the operation of renewal is very loaded down with trivial details.
