RU2557267C2 - Safe automobile road and its operating method - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: automobile road with a hard coating includes at least one turn to the left, at the location of which it includes (on the road way) artificial unevenness in the form of a sleep hump with a transverse profile providing a possibility of jerkless run over it of a vehicle with stepped exit; with that, the artificial unevenness is made at a tangent to the road axis at an angle contributing to movement of the vehicle to the left. An operating method of the automobile road, which involves movement along it of vehicles, consists in the fact that movement of vehicles is performed along the proposed automobile road.

EFFECT: increasing road traffic safety, simplifying a construction technology, increasing repairability and reducing costs for maintenance and operation.

Description

The invention relates to the field of construction, in particular to the construction of roads, and can be applied in the construction and repair of paved roads.

Known paved road, comprising at least one turn to the right (patent for invention RU 2519265 C2, E01C 1/00, publ. 06/10/2014, bull. No. 16). However, its disadvantages are complex construction technology, low maintainability, high maintenance costs.

According to its technical solution, the specified road is the closest to the proposed invention.

The invention was tasked with simplifying construction technology, increasing maintainability, and reducing maintenance and operating costs.

EFFECT: increased traffic safety, simplified construction technology, increased maintainability, reduced maintenance and operation costs.

The technical result is achieved due to the fact that the road with a hard surface, including at least one left turn, at the turning point on the carriageway, contains an artificial bump in the form of a “speed bump” with a transverse profile, which makes it possible to smoothly hit the vehicle on it means with a stepped exit, while the artificial roughness is made relative to the tangent to the axis of the road at an angle conducive to the movement of the vehicle to the left.

In FIG. 1 shows a section of a highway with a left turn, top view; in FIG. 2 shows an artificial roughness, side view.

The arrow shows the direction of movement of the vehicle.

The road contains lanes 1 and 2, separated by the axis of the O1O2 road.

On lane 2 there are artificial bumps 3, 4, 5, 6, 7, each of which is located relative to the tangent to the axis of the road O1O2 at an angle α.

The angle α is acute (α <π / 2).

In FIG. 1, the wheel 8 of a vehicle (not shown) is conditionally shown at the time of exit from the artificial roughness 6.

The artificial roughness 6 (Fig. 2) is made with a transverse profile (section) in the form of a right triangle, the larger leg of which C is located on the surface 9 of the carriageway (lane 2), and the smaller b is made on the exit side of the vehicle.

The road is used as follows.

The vehicle, when driving along a lane in a bend from left to right, alternately passes through artificial bumps 3, 4, 5, 6, 7. Due to the fact that α <π / 2, onto the wheel 8 of the vehicle when it exits from artificial bumps 3, 4, 5, 6, 7, a torque M will act, facilitating the movement of the vehicle wheel 8 to the left. The torque M acts counterclockwise and seeks to direct the vehicle away from the shoulder 10 and thus prevent the vehicle from colliding with a guard or other obstacle. The probability of leaving the road (with a fall, for example, into a ditch) will also be reduced in case of loss of vehicle control by the driver. In addition, the exit to lane 2 of an oncoming vehicle moving in lane 1 will be undesirable for the driver of the indicated means, since on the side of the road it will experience greater resistance to movement than when turning right on its own lane 1.

The method of operation of the road, including the movement of vehicles on it, is that the movement of vehicles is carried out on the above road.

To implement the proposed technical solutions, artificial irregularities of the type “speed bump” or of the type of “noise band” with a crest height of 10 to 30 and 10 to 70 mm, respectively, can be used.

Claims (3)

1. The road with a hard surface, comprising at least one left turn, characterized in that at the turning point on the carriageway it contains an artificial bump in the form of a “speed bump” with a transverse profile, allowing a smooth approach of the vehicle from step exit, while the artificial roughness is made relative to the tangent to the axis of the road at an angle conducive to the movement of the vehicle to the left. 2. The road according to claim 1, characterized in that the artificial bump is made with a transverse profile in the form of a rectangular triangle, the larger leg of which is located on the surface of the road, and the smaller leg is located on the exit side of the vehicle with artificial bumps. 3. The method of operation of the road, including the movement of vehicles on it, characterized in that the movement of vehicles is carried out on the road under item 1 or 2.
