Definitions

• the present invention relates to a device for road and urban mobility and for solving the congestion problem.
• 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.
• GPS Global Positioning System
• This system is fully operational and open to the general public.
• 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.
• 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.
• 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.
• the device 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. Service that will be provided by means of a central server adapted and able to communicate with this type of device.
• this onboard device comprises a vehicle guidance system, in synergy with a central server, characterized in that it comprises means for: reception of the signal relating to the position of the vehicle from a satellite
• any request transmitted to the central server will be: vehicle speed, remaining distance and remaining duration of the journey on a section;
• one of the following events triggers the transmission of the request at an appropriate time: approach of a section node, slowing down for a duration greater than a predetermined threshold, stopping or restarting after a stop;
• the duration is not the same between two requests (variable periodicity or asynchronous transmission) for the updates
• the route is recalculated by the central server for a distribution of vehicles equipped and concerned in the road capillarity in its entirety;
• the route is continuously updated according to the traffic conditions, represented by the parameters captured / calculated: speed, distance and time; and
• a node is a bifurcation, a junction or a junction
• -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.
• the device is integrated in a housing and is composed of five interconnected modules: -Receiver Satellite Position Data (RX);
• MRX - Adaptive Input Processor Interface
• -Processor or configuration Central Unit, Central Memory and Exchange Unit;
• 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.
• 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.
• 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.
• the device in its operation is capable of:
• the processor or configuration can: ⁇ Extract satellite coordinates position coordinates;
• the device according to the present invention operates automatically in M2M ("machine-to-machine" in English terminology) and makes it possible to check the fluidity in the road capillary before any engagement on a section so that the user arrives at his destination in optimal time and with reduced oil consumption and greenhouse gas emissions.
• M2M machine-to-machine
• the program or algorithm of the processor updates by query (Vij, DRj, TRj), whenever necessary, the values of the captured elements.
• the processor analyzes the captured / calculated data before setting the appropriate time (tj) to send a request depending on whether the vehicle approaches the other stub node, or slows down for a significant amount of time, or stops or restarts after a stop.
• the device displays only the image of the only section of track on which the vehicle is located.
• the transmitter / receiver of the device communicates only when necessary, which results in a saving in the consumption of the bandwidth of the bidirectional radio support.
• Said bandwidth saving allows a large number of users requesting the service to be served.
• the vehicle guidance system enabling the onboard device in synergy with the central server to manage and make the road capillary fluid, comprises the following steps:
• a device comprising a processor, embarked on board a vehicle with a signal relating to the position of the vehicle from a satellite;
• the device according to the invention is particularly intended to communicate with a dedicated central server for the resolution of the bottleneck problem.
