Description

Dow Roadway with optical-kinetic brake and way of adjusting roadway to reduce the speed of passing vehicles

Technical field

The present invention relates to an optical-kinetic brake pavement and a method of modifying the pavement to reduce the speed of passing vehicles.

BACKGROUND OF THE INVENTION

There are a number of critical points on the road network, such as pedestrian crossings and junctions, or confusing places with low visibility for the incoming driver. Also, most entrances to the municipality are a critical point, because a driver arriving in the municipality often does not realize its high speed and does not slow down to the required maximum speed in the village right at the entrance to the village, but only later. At present, such places are usually marked by vertical road signs indicating a dangerous place or adjusting the maximum permitted speed. The so-called optical psychological brake, which is a horizontal road sign consisting of a series of light lanes that extend perpendicular to the direction of travel of the vehicles and their distance gradually decreases in the direction of travel of the vehicles, is less frequently used. The disadvantage of such an optical psychological brake is that it is of an optical nature only, and therefore drivers traveling through such a place repeatedly may become accustomed to the presence of the optical brake and may ignore it, which deprives the brake of its effectiveness. Another possible solution is to use a deceleration threshold which, by its physical shape, forces the driver to slow down to a speed at which the threshold can be safely crossed; otherwise, drivers risk damaging their vehicle. However, the disadvantages of retardation lanes are their relatively higher purchase price, increased noise when passing vehicles and a negative impact on the technical condition of vehicles. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a device which eliminates these disadvantages of the prior art.

SUMMARY OF THE INVENTION

This object is solved according to the invention by an optical-kinetic brake for reducing the speed of passing vehicles, comprising at least one lane in which a plurality of transverse lanes which are transverse to the direction of travel in said lane are arranged and arranged so that width measured in

Preferably, the depth of the transverse strips is 2 to 6 cm, preferably 3 to 5 cm, being equal to or not more than 2 cm greater than the height of the elastic mass in the transverse stripe.

In a particularly preferred embodiment, the side walls of the transverse strips forming a transition from the road surface to the bottom of the transverse strips form an angle of 30 to 60 ° with the perpendicular to the road.

Disadvantages of the prior art are also obviated by a method of modifying a roadway to reduce the speed of passing vehicles, in which, according to the invention, a system of transverse strips which are transverse to the direction of travel in said lane and arranged so that their width measured in direction of travel progressively shortens, while the closest walls of adjacent transverse strips form a ribbed system with an intermediate portion of the road transverse to the direction of travel, each rib separating two adjacent transverse strips and the width of the ribs measured in the direction of travel in said path the ribs are at least partially filled with a flexible material having a color contrasting to that of the road.

The transverse strips are preferably milled to a depth of 2 to 6 cm, most preferably to a depth of 3 to 5 cm.

Preferably, the step of filling the milled transverse strips with an elastic mass is accomplished by casting the transverse strips with a silicone-based mass having a white or yellow color.

From the point of view of driving noise, it is advantageous if the depth of the milled transverse strips is equal to the height of the elastic mass in the transverse stripe or at most 2 cm greater.

From an optical point of view, it is preferable that the spacing of adjacent transverse strips is 5 to 7 cm and the width of the transverse strips gradually decreases from 100 to 10 cm.

In order to prolong the durability of the treated pavement, it is advantageous for the elastic mass to be locked in the milled transverse strips by means of fastening means, in particular screws or nails, at the end of the treatment.

BRIEF DESCRIPTION OF THE DRAWINGS

An exemplary embodiment of the invention is shown schematically in Figure 1, in which a cross-sectional view of an optical-kinetic brake roadway according to the invention is shown.

Description of exemplary embodiments

As can be seen from FIG. 1, in an exemplary embodiment of the invention, a set of transverse strips 2, which are perpendicular to the X direction of travel in the respective carriageway 1, is milled into the pavement 1. substantially equal to or less than the width of the respective road strip. The width of the transverse strips 2, i.e. their dimension in the direction of travel in a given road strip, is 10 to 100 cm, and they gradually narrow in the direction of travel, i.e. towards the critical or risk area of the road. The non-milled road sections 1 between the transverse strips 2 form transverse ribs 4, the width of which is substantially constant, i.e. the mutual distance of the transverse strips 2 is substantially constant and is preferably 5 to 7 cm. The milled transverse strips 2 are partially embedded in a resilient mass 3, for example on a silicone base, preferably white or yellow. In any case, the color of the elastic mass 3 poured into the milled transverse strips 2 should be contrasted with the color of the roadway 1. The purpose of the elastic mass 3 is to reduce the load on the shock absorbers and axles of passing vehicles, reduce passing noise while acting as a classic optical psychological brake , consisting of transverse contrast strips, the distance of which gradually decreases in the direction of travel X.

The invention has a number of advantages over prior art devices. Milling the transverse strips 2 into the roadway 1 is considerably less expensive than building the retardation thresholds. The disadvantage of physical wear of vehicles due to crossing the deceleration thresholds is largely eliminated, since the differences between the lowest point of the elastic mass 3 and the highest point of the adjacent roadway part 1 are at most several centimeters. Also, the noise level of vehicles when driving is reduced compared to plastic retarders. The transition from the level of the roadway 1, that is from the level of the ribs 4 to the bottom of the milled transverse strips 2 need not be rectangular, it can also be slightly beveled,

-4the approach to the transverse lanes 2, or the exit from them less sharp. In the cross-section of the roadway 1 with the transverse strips 2 so milled, the transverse strips 2 would then have a trapezoidal shape. The inclination of the entry and exit side walls of the transverse strips 2 from the perpendicular to the plane of the road 1 or the bottom plane of the transverse stripe 2 is preferably 30 to 60 °.

The resilient mass 3 should have a surface such that there is no skidding on the vehicle, so it should meet similar requirements as for example the artificial surface of sports fields and the like. This resilient mass 3 can be fixed on the roadway 1 by means of nails or screws and the like for a longer service life.

Obviously, Fig. 1 does not show the optical-kinetic brake to scale and is only schematic. The width of the individual transverse strips 2 decreases generally in the direction of travel towards the critical area of the road, but it is possible to arrange several transverse strips 2 of equal width, i.e. several transverse strips 2 with a minimum width, at the end.

Adding a third dimension to the classical psychological brake greatly increases its long-term effectiveness. It contains not only an optical perception for the driver (the driver approaching the tapered transverse strips subconsciously brakes), but also the movement, respectively. kinetic perception (the driver also brakes when entering or before driving on uneven surfaces causing slight vibration of the vehicle).
