Description

DEVICE FOR SECURING THE CROSSING OF PIETONS ON A PASSAGE.

The present invention relates to a device for securing the crossing of pedestrians on a passage intended for its specific use for the crossing of a road (called "pedestrian crossing").

By pedestrian crossing, is meant, in the sense of the present invention, a portion of the road (or pavement) designed to allow pedestrians to cross the road by forcing them to remain grouped in a visible space by motorists.

The pedestrian crossings are intended to allow pedestrians to cross the roadway safely with respect to road traffic. But the safety of pedestrians on these passages is currently not guaranteed (due in particular to a dense urban traffic).

The security of pedestrian crossings is therefore, nowadays, become more and more necessary, and even more so if the pedestrian crossing is not managed by traffic lights and / or if it is in an urban environment . In 2013, more than 14% of people killed on the road were pedestrians and almost two thirds of the pedestrians killed were in urban areas. Finally, 46% of pedestrians killed were traveling at night, with a peak of accident, recorded in winter, between 18h and 21h.

In a regulatory manner, a car driver is obliged to give way, if necessary by stopping, to a pedestrian (more vulnerable than the driver in his vehicle) engaging regularly in the crossing of a roadway or protester clearly intend to do so. However, it may happen that the driver is not able to do so because when approaching certain crosswalks, the driver has not been or could not be informed of the presence of a driver. pedestrian preparing to cross the roadway and / or entering the roadway. This is even more detrimental in some sensitive areas. As a result, certain pedestrian crossings, by their configuration, may partially mask the vision of the motorist and the pedestrian, particularly if the passage is located near a bend (obstructing the street), or in the event of lateral parking near the passage, or because of the presence of natural obstacles (such as trees, etc ...) near the passage. In such configurations, there is no visibility for the pedestrian, day or night. At present, there is no real technical solution to solve such a problem, except solutions implementing permanent lighting but without detection device.

In order to respond to the problem and to overcome the aforementioned disadvantages, while contributing to sustainable development (energy saving and urban development, the applicant has developed a device that is able to warn the motorist of the presence of a pedestrian who is about to cross the road, so as to signal a danger (both for the motorist, for the pedestrian or animal crossing the road).

More particularly, the subject of the present invention is a device for securing the crossing of pedestrians on a pedestrian crossing crossing a roadway, characterized in that it comprises: four poles with shape memory polymer, said stubs being arranged in pairs of parts and other of the roadway so as to mark the pedestrian crossing, each post being equipped with an infrared presence detector located at a height of between 50 cm and 80 cm from the ground, and at least one electroluminescent diode (usually designated by the acronym LED for the terms "light-emitting diode") disposed at the top of said post, and a management controller able to manage and regulate the operation of the entire device and being powered by a network electrical distribution (typically with a single-phase power supply at 220 V. In the context of the present invention, it will preferably use poles in po Such posts have the following advantages: in the context of environmental certification, including the sustainable development approach, the posts of the device according to the invention are made from recycled and end-of-life recyclable materials, when 'a shock with a vehicle (car or motorcycle for example), such posts will not break and will bend under the effect of the pressure exerted by the vehicle, then respend their initial shape after the shock,

Finally, the very nature of the constituent polymer of the posts makes it possible to avoid any problem of corrosion. As elastomeric polyurethane posts used in the context of the present invention, there may be mentioned those manufactured and marketed by the company SODILOR.

The posts can advantageously have a height of between 80 cm and 1 m.

Preferably, each post may be equipped with a plurality of light emitting diodes in the form of a strip.

The infrared presence detector of each post is preferably located at a height of about 60 cm from the ground to allow the detection of children, and also some animals large enough to cause an accident if they were hit by the vehicle (for example, guide dogs for the blind).

The management controller of the device according to the invention can typically be in the form of an integrated electronic card in the base of one of the posts.

The operation of the device according to the invention is as follows: when, day or night, a pedestrian seeks to engage on the pedestrian crossing, it will cross the line formed by the pair of posts disposed on the side of the roadway where it is, to be detected by the infrared presence detectors placed on the steel posts; the management controller will then automatically trigger the blinking of the LEDs (for example in the form of an LED strip) at the top of the posts, constituting a warning signal for the vehicle, at the approach of the pedestrian crossing. This prevents the driver from being surprised and allows him to anticipate the presence of a danger on the taxiway.

Preferably, the security device according to the invention may further comprise a lighting pole equipped with a LED technology luminaire, said management controller being then disposed either at the base of one of the posts, or in said lighting pole. The management automat, managing both the LEDs of the posts and the lighting mast, allows the lighting of the integrated LEDs at the top of the posts and that of the LED luminaire placed on the lighting mast.

Thus, a pedestrian engaging at night, on the pedestrian crossing automatically triggers both the flashing alert, placed on the posts that frame the passage on each side, and a specific ignition by the LED technology luminaire, placed on the mast, which directly illuminates the passage by allowing a better visibility of the pedestrian. Thus, the driver, who arrives in particular in a dangerous area, is not surprised and therefore pays much more attention to the pedestrian on the road, even in the middle of the night.

The device according to the invention is particularly intended for Local Communities (Cities, Towns) with dangerous or insecure axes, on which are arranged pedestrian crossings. Other advantages and features of the present invention will result from the description which follows, given by way of nonlimiting example and with reference to the appended figures: FIG. 1 represents a perspective view of a preferred embodiment the device according to the invention (with lighting pole) at a pedestrian crossing; FIG. 2 represents a view from above of the device according to the invention shown in FIG. 1.
