Definitions
- This disclosure relates to the field of road traffic control.
- Road navigation assistance methods can combine connected technologies, systems and equipment with connectivity solutions in order to generate recommendation messages intended for connected vehicles, as well as, in the case of autonomous vehicles, generate instructions, allowing semi-autonomous or even completely autonomous driving.
- the connected technologies, systems and equipment may in particular be chosen from cameras, radars, lidars, location systems, map data and driver monitoring systems.
- the connectivity solutions can for example be GPS navigation assistants or solutions implementing 5G.
- the current methods of road navigation assistance generally make use of pre-embedded data, the regular updating of which is not always ensured. Additionally, Over-The-Top road route calculation services may be used, but these services are not always reliable. Thus, the current methods of road navigation assistance and bypass services are most often ineffective in avoiding the formation of bottlenecks, especially in real time.
- each recommendation message comprising at least one instruction to be adopted by at least one vehicle of the at least some of the vehicles and/or by at least one connected device which is not on board the vehicles to make the traffic situation more fluid, the data obtained in step /a/ further comprising, for each connected device , a score associated with the connected equipment.
- vehicle means a vehicle that may or may not be motorized.

- the data obtained in step /a/ further includes, for each connected device, a priority level associated with the vehicle carrying the connected device.
- the sub-section of vehicles for which respective instructions are generated can thus be defined according to the respective priority levels.

- the respective instructions to be adopted are defined according to the respective scores.
- the calculation phase can thus be refined according to whether or not the instructions are complied with in the recommendation messages generated by the users.
- the security of the defined instructions can be increased by targeting users likely to respect the instructions in the recommendation messages.
- the instructions intended for the user equipment of the vehicle sub-part can then take into consideration the unpredictable character of the user who tends not to respect the instructions in the recommendation messages generated, which further increases the security of the defined instructions.
