Description

Dispositif pour la mobilité routière et urbaine et pour la rés  Device for road and urban mobility and for the res
La présente invention concerne un Dispositif pour la mobilité routière et urbaine et pour la résolution du problème d'embouteillage. The present invention relates to a device for road and urban mobility and for solving the congestion problem.
Les moyens et techniques mis en opération actuellement n'aident pas à utiliser la capillarité routière et ne permettent pas d'anticiper et d'intervenir pour faciliter le flux routier, en ville et entre les villes. Une information précise et une image exacte sur l'évolution du trafic: nombre et destination des véhicules n'est pas disponible pour réagir en temps réel, soit à partir d'un Centre de la Sécurité Routière ou d'un Centre Informatique privé. On constate qu'à présent, les données de trafic sont fragmentées, ville et alentours, et le facteur inter-villes n'est pas pris efficacement en compte. De surcroît, il est impossible de communiquer en liaison radio bidirectionnelle avec une catégorie spécifique d'usagers de la route. Par exemple, un camion, chargé ou non, se trouvant sur une voie encombrée, ne sera pas guidé/aiguillé sans faute vers une voie secondaire de la capillarité routière dans l'état actuel des choses. L'occurrence d'embouteillages n'est pas traitée en sa globalité en raison de manque de moyens dans le passé, performance et coût exorbitant des technologies. On connaît dans l'art antérieur les dispositifs de type GPS {«Global Positioning System» en terminologie anglo-saxonne) qui communiquent avec des satellites pour guider des véhicules. Ce système est totalement opérationnel et ouvert au grand public. Cependant, ce type de dispositif GPS ne permet pas de prendre en compte de façon efficace les conditions de circulation dans la capillarité routière afin de permettre à un conducteur d'un véhicule de suivre le meilleur itinéraire de la capillarité routière. Prenant en compte l'état de l'art antérieur, le dispositif est proposé pour anticiper les embouteillages et rendre plus fluide le trafic. Un des buts de l'invention est également de réduire la consommation de Détrole Dar les véhicules, et de réduire l'émission de gaz à effet de serre. L'invention est destinée à ce que tout déplacement soit moins risqué et moins aléatoire. Ainsi, au lieu de libérer les usagers immobilisés/retenus sur la route par un ou plusieurs agents de la circulation. Le dispositif et un système de guidage lui est associé, une fois déployés en nombre suffisant, anticipent automatiquement et empêchent tout développement en embouteillage. Grâce aux moyens de communication bidirectionnels mis en œuvre dans la présente invention, un conducteur d'un véhicule peut éviter les embouteillages, en respectant et en suivant l'instruction de prise de tronçon affiché jusqu'à destination.  The means and techniques put in operation at present do not help to use the road capillarity and do not allow to anticipate and intervene to facilitate the flow of road, in city and between cities. Accurate information and an accurate image of the evolution of traffic: number and destination of vehicles is not available to react in real time, either from a Road Safety Center or a Private Computing Center. It can be seen that traffic data is fragmented now, in the city and the surrounding area, and the inter-city factor is not taken into account effectively. In addition, it is impossible to communicate in two-way radio with a specific category of road users. For example, a truck, loaded or not, on a congested track, will not be guided / referrals without fault to a secondary road of road capillarity in the current state of things. The occurrence of traffic jams is not treated in its entirety due to lack of resources in the past, performance and exorbitant cost of technology. In the prior art are known devices GPS ("Global Positioning System" in English terminology) that communicate with satellites to guide vehicles. This system is fully operational and open to the general public. However, this type of GPS device does not effectively take into account the traffic conditions in the road capillarity to allow a driver of a vehicle to follow the best route of road capillarity. Taking into account the state of the prior art, the device is proposed to anticipate congestion and make the traffic more fluid. One of the aims of the invention is also to reduce the consumption of diesel fuel in vehicles, and to reduce the emission of greenhouse gases. The invention is intended that any movement is less risky and less random. Thus, instead of releasing users immobilized / held on the road by one or more traffic police. The device and a guidance system is associated with it, once deployed in sufficient numbers, automatically anticipate and prevent any development in traffic jams. Thanks to the bidirectional communication means implemented in the present invention, a driver of a vehicle can avoid traffic jams, by respecting and following the stopping instruction posted to the destination.
Le dispositif selon l'invention permet de remédier à cet inconvénient. En effet, selon une première caractéristique, Il est constitué d'un ensemble de cinq modules électroniques dont un processeur connecté à deux interfaces. Une interface MRX formate le signal reçu continuellement du satellite par un récepteur, RX. L'autre, MTRX, est connectée à un émetteur/récepteur en même temps que le processeur. Le processeur analyse et extrait les données de positions (longitude et latitude) et envoie les requêtes. L'émetteur/récepteur, TRX, échange avec un serveur central de façon bidirectionnelle. Le tout est intégré dans un boîtier embarqué dans tout véhicule participant et bénéficiant d'un service de mobilité et d'optimisation du flux routier. Service qui sera assuré au moyen d'un serveur central adapté et capable de communiquer avec ce type de dispositif.  The device according to the invention overcomes this disadvantage. Indeed, according to a first characteristic, it consists of a set of five electronic modules including a processor connected to two interfaces. An MRX interface formats the signal received continuously from the satellite by a receiver, RX. The other, MTRX, is connected to a transceiver at the same time as the processor. The processor analyzes and extracts the position data (longitude and latitude) and sends the requests. The transmitter / receiver, TRX, exchanges with a central server bidirectionally. Everything is integrated in an on-board box in any participating vehicle and benefiting from a mobility service and optimization of the road flow.

-Au sens de la présente invention:  In the sense of the present invention:
-un nœud est une bifurcation, un carrefour ou une jonction;  a node is a bifurcation, a junction or a junction;
-un tronçon est la voie qui relie deux nœuds; -un itinéraire est formé d'une série ou succession de tronçons; et -une capillarité routière est formée de tous les itinéraires possibles reliant un point de départ à un point d'arrivée que soit par une combinaison de: voies, rues, avenues, boulevards, routes ou/et autoroutes. -a stretch is the path that connects two nodes; a route is formed of a series or succession of sections; and a road capillarity is formed of all the possible routes connecting a starting point to a point of arrival that is by a combination of: ways, streets, avenues, boulevards, roads and / or highways.
-Le dispositif est intégré dans un boîtier et est composé de cinq modules interconnectés: -Récepteur Satellite de données de position (RX);  -The device is integrated in a housing and is composed of five interconnected modules: -Receiver Satellite Position Data (RX);
-Interface Adaptative Entrée Processeur (MRX);  - Adaptive Input Processor Interface (MRX);

-Ledit dispositif reçoit en temps réel du satellite des informations corrélées, MTX les met en conformité et les présente au Processeur pour les analyser et en extraire les coordonnées de position. Ledit Processeur calcule périodiquement et sans arrêt les trois paramètres ou variables: Vitesse ( ij), Distance Restante (DRj) et Durée Restante (TRj) à l'approche du véhicule de l'autre nœud d'un tronçon. Ces trois variables constituent toute requête. Le programme ou l'algorithme du Processeur ne transmet pas systématiquement les requêtes mais, pour quelques unes, il détermine l'instant approprié (tj) pour renseigner un ordinateur distant, situé dans un centre dédié à l'observation et à la gestion de la circulation des véhicules équipés et fonctionnant en temps réel (sept jours sur sept et vingt-quatre heures sur vingt-quatre). L'algorithme déclenche l'envoi de requêtes à des instants (tj) pour notifier soit: l'approche de l'autre nœud du tronçon, ou un ralentissement notable ou un arrêt ou un démarrage après un arrêt. Alors, l'ordinateur en recevant ces requêtes, y tient compte en mettant sa Base de Données numérique à jour, réévalue la situation globale du trafic dans la capillarité routière et répond. La réponse est une actualisation d'itinéraire et une instruction que le processeur conserve en mémoire l'itinéraire et présente l'instruction à l'usager: affichage d'un seul tronçon et une annonce vocale que l'usager doit respecter et suivre. Ainsi, un tronçon et une annonce qui se succèdent automatiquement guident l'usager à atteindre sa destination. L'objectif d'avoir un flux optimisé partout en ville (boulevard, avenue, rue) et les routes et autoroutes entre-villes ne sera possible qu'avec l'adoption du dispositif par un nombre très important de conducteurs.  -This device receives real-time information from the satellite correlated, MTX puts them in compliance and presents them to the processor to analyze and extract the position coordinates. Said processor periodically and continuously calculates the three parameters or variables: Speed (ij), Remaining Distance (DRj) and Remaining Time (TRj) at the approach of the vehicle of the other node of a section. These three variables constitute any request. The program or the algorithm of the processor does not systematically transmit the requests but, for some, it determines the appropriate moment (tj) to inform a remote computer, located in a center dedicated to the observation and the management of the the circulation of vehicles equipped and operating in real time (seven days a week and twenty-four hours a day). The algorithm triggers the sending of requests at times (tj) to notify either: the approach of the other node of the section, or a noticeable slowdown or a stop or a start after a stop. Then, the computer receiving these requests, takes into account by updating its Digital Database, re-evaluates the global traffic situation in the road capillarity and responds. The response is a route update and an instruction that the processor keeps in memory the route and presents the instruction to the user: displaying a single section and a voice announcement that the user must respect and follow. Thus, a section and an announcement that follow one another automatically guide the user to reach his destination. The objective of having an optimized flow throughout the city (boulevard, avenue, street) and the inter-city roads and highways will only be possible with the adoption of the device by a very large number of drivers.
