Definitions

  • the present invention relates to the prevention of oncoming-traffic congestions.
  • the invention relates to an oncoming-traffic-congestion-prevention-device, to a method for preventing a traffic congestion on an oncoming lane and to a program element.
  • Roads with a high traffic volume are often prone to traffic congestions. For example, if there is a traffic obstruction on a road, e.g. a slow vehicle, there is the risk that other vehicles drive with a high velocity into the traffic obstruction which may lead to a traffic congestion.
  • a traffic obstruction on a road e.g. a slow vehicle
  • TMC traffic message channel
  • classic radio broadcasts These protocols can also be used to provide alternative routes such that the traffic congestion can be dissolved.
  • a first aspect of the invention relates to an oncoming-traffic-congestion-prevention-device for a first vehicle driving on a first lane in a first direction.
  • the oncoming-traffic-congestion-prevention-device comprises a receiving unit, a transmitting unit and a processing unit.
  • the receiving unit is configured for receiving first data about a traffic obstruction on a second lane from a second vehicle driving on the second lane in a second direction opposite to the first direction and for transmitting the first data to the processing unit.
  • the processing unit is configured for generating second data comprising information about the traffic obstruction and for transmitting the second data to the transmitting unit.
  • the transmitting unit is configured for transmitting the second data to a third vehicle driving on the second lane when the first vehicle is located at a position which is located more than one kilometer away from the position at which the first data was received by the first vehicle.
  • the oncoming-traffic-congestion-prevention-device is configured for transporting information about a traffic obstruction on the oncoming lane from the second vehicle to the third vehicle which is driving behind the second vehicle, wherein this information is transported over at least one kilometer.
  • the invention is based on the knowledge that traffic congestions could be avoided or at least minimized if vehicles coming from behind become aware about the traffic congestion.
  • traffic congestions could be avoided by informing vehicles coming from behind to slow down in advance. By slowing down to an advised velocity, vehicles coming from behind could also have a lower fuel consumption and produce less air pollution, meanwhile giving time for the traffic congestion to dissolve.
  • the inventors also recognized that it may be advantageous to use a decentralized system, i.e. car-to-car (C2C) communication, since centralized systems as TMC or other protocols may adapt too slowly. In particular, it could be the case that the route recommended by TMC is already congested.
  • C2C car-to-car
  • the first, second, third vehicle or any other vehicle described in the context of the invention may be any kind of road vehicle, for example, a motor vehicle, an automobile, a car, a motorcycle or a truck.

  • the entry to the alternative route may be an exit of a highway on the second lane on which the second vehicle and the third vehicle are driving.
