Presentation of the technical problem:

° France, like many developed countries, has a large network of secondary roads (national, departmental, municipal, highways, etc.) with a two-way traffic direction that are free, or not, of visual separator delimiting their traffic lanes (nearly ^ 0 of a million kilometers for France). This road network is the most accident-prone in comparison with the main one-way and / or double-lane roads with physical separators (only thirty percent of fatal accidents take place on motorways; see for example: http: / /sosconso.blog.

lemonde.fr/2014/02/05/ou-reduire-les-vitesses-la-liste-desdepartements-les-plus-meurtriers/). This also induces public apprehension with regard to this network of secondary roads, which is common knowledge (see for example: h http://www.lalsace.fr/actualite/2016/04/19/les-francais -ontpeur-des-routes-secondaire- /).

For historical reasons, local constraints of development or construction of these secondary roads in the direction of two-way traffic, these lanes, often narrow, frequently present dangerous sites where the visibility of drivers of motorized vehicles is low or reduced then that they cross there simultaneously (turns, laces, climbs and peaks of curves, crossings, etc.). The risks of collisions and / or accidents of • X> vehicles in simultaneous presence on these dangerous sites are all the more important as they circulate there quickly and / or as the weather conditions face, rain, frost, mist, snow , dark night, etc.), the latter making it more difficult to drive and control a motorized vehicle. Road tragedies such as that of Puisseguin (33570), on 23 October 2015, regularly cause road accidents, causing forty-three deaths, a coach having struck a semi-trailer in a spike, the two vehicles not having been warned in time of their simultaneous presence on site when approaching the turn in question, which would have enabled them, if not, to reciprocally adjust their speeds and road placements, as to avoid death forty-three people in all probability.

AS

Traditionally, the devices dedicated to the problem solved by according to the invention are convex mirrors positioned, in height, on the road sites identified as dangerous.

These mirrors make it possible to extend the field of vision of the drivers of motorized vehicles coming in particular from one another. But they have the disadvantages of being high (vs placed in each direction of lane traffic, and up to the eyes of the drivers), to be passive and therefore to require the attention of drivers, even to require knowledge dangerous sites thus equipped, these mirrors being indeed of reduced size.

In addition, because of its optical characteristics (mirror this type of device also has the disadvantage of inducing a poor appreciation of the distance and the speed of the vehicle occurring in the opposite direction. This is problematic when it comes to reacting in time and wisely when necessary. Indeed, the approach speed of vehicles is more difficult to interpret by means of the mediation of a mirror and, at night, in the absence of public lighting, the view of the headlights of a vehicle in the mirror may suggest to a driver of a motorized vehicle that the one occurring in the opposite direction to his is in front of him, so the latter actually arrives laterally.

There are also road signs with passive markings reflecting the light of the headlights of vehicles, which are most often placed in the dangerous bends of the roads, and whose essential function is only to signal the existence of said bend. These devices are also more effective at night than during the day, because of their passive reflective functionality, and therefore inoperative today.

There are road signaling devices integrating two separate terminals, which can also, but more rarely, integrate a vehicle detection assistance system (video camera) for the use of its human operators. But these devices i) are used intermittently during road improvement works in order only to regulate an alternating flow of traffic made necessary by said works ii) are not dedicated to dangerous sites on two-way roads and highways and to technical safety problems that these pose iii) are not designed and do not function to establish and communicate to the drivers of motorized vehicles, on a 3 ° road with a two-way traffic direction and dangerous sites, the information is continuous, instantaneous, in real-time, reciprocal, symmetrical, and dynamic of their presence on site in opposite directions to each other.

Furthermore, there are traditionally three-color traffic signal lights which can be fitted with detectors of moving masses (A).

There are also traditionally isolated illuminated road signs, indicators of the speeds of vehicles detected by them (B).

Finally, there are road radars dedicated to regulatory speed control on roads and motorways (C). These devices of type (A), (B), (C) above are not designed and do not operate to inform continuously, instantaneously, in real time, vice versa, symmetrically, and dynamically the drivers of vehicles coming in. opposite direction of each other from their simultaneous presence on dangerous sites (ie affected by low visibility or reduced visibility) of roads and highways whose direction of direction is bidirectional. In these respects,

- More specifically, these traditional devices (A) (B) (C) above, (B) and (C) above in particular, have been designed and have always operated from the outset that they do not continuously inform, instantaneous, in real time, reciprocal, symmetrical, and dynamic the drivers of motorized vehicles from their simultaneous presence on approach and in opposite directions from each other, particularly or not, on the dangerous sites presented by roads and highways whose direction traffic is bidirectional.

Said terminals (2) (3) retransmit and exchange instantaneously and in real time the information of the 12 simultaneous presence of vehicles occurring in opposite directions to each other by means of their modules for receiving and receiving information of the masses detected ( 9) simultaneously and / or their buried wire connection (12).

Each of the terminals (2) (3) then emitting, instantly and simultaneously, a light and / or sound and / or radio and / or radio and / or opto-electromagnetic and / or wifi and / or telephone warning for the use of each of the conductors of the vehicles in simultaneous approach on area.

The warning in question is pre-qualified, pre-segmented and pre-programmed by the programming control modules (8) and the detection of moving masses (6) of the terminals (2) (3) to be the most relevant according to the cases that arise. : occurrence of vehicles in opposite directions to each other, and / or more precisely very (too) fast speed of said vehicles (together or separately) with regard to the road morphology; significant volume of said vehicles (truck, coach, construction machine, agricultural machine, etc.); possible multiplicity of said vehicles.

The device (1) according to the invention makes it possible, when approaching dangerous sites (whose visibility is low or reduced) to roads and highways in the direction of two-way traffic,

To constantly warn drivers of motorized vehicles approaching in opposite directions to each other of their simultaneous presence on sites in a continuous, instantaneous, real-time, reciprocal, symmetrical, and dynamic manner.
