Definitions

  • the invention relates to a method for recognizing overtaking maneuvers in road traffic within a route section.
  • Overtaking maneuvers always occur in road traffic when two vehicles on the same lane are moving in the direction of travel at different speeds, so that the faster vehicle moves past the slower vehicle. Overtaking maneuvers are often the trigger for serious accidents, so that overtaking bans are imposed by the authorities on accident-prone route sections. These overtaking bans can affect all vehicles or only target certain types of vehicles or vehicles with a defined permissible total mass.
  • the overtaking bans can either be set up permanently or adapted to the traffic situation using dynamic traffic management systems. In order to be able to detect violations of existing overtaking bans, traffic monitoring systems are necessary.
  • a process unit processes the images from the stereo camera into height images and analyzes these height images to determine position variables of two vehicles relative to one another. This enables the detection of the vehicle speed and overtaking maneuvers as well as the evaluation of the current traffic flow.
  • the object of the present invention is to provide a method provide for the detection of overtaking maneuvers in road traffic within a route section that enables traffic monitoring of route sections independently of their route.
  • a method according to the invention for recognizing overtaking maneuvers in road traffic within a route section comprising the following steps: detection of the entry into the route section of at least two vehicles by a first control device; Determining an entry sequence of the at least two vehicles when entering the route section; Detecting the exit from the route section of the at least two vehicles by a second control device; Determining an exit sequence of the at least two vehicles when exiting the route section; and recognizing overtaking maneuvers by comparing the entry sequence with the exit sequence.
  • the proposed method has the advantage that route sections can be monitored regardless of their length and route.
  • the method according to the invention can be used in the area of curved and / or hilly road sections.
  • the detection of driving into the route section can include the determination and assignment of at least one identification feature for each of the at least two vehicles by the first control device
  • the detection of the exit from the route section can include the determination and assignment of the at least one identification feature for each of the at least two vehicles by the second control device.
  • the at least one identification feature of the at least two vehicles can include the vehicle registration number or a vehicle identification number.
  • the at least one identification feature can be determined and assigned for each of the at least two vehicles by the first control device using a first image recording and / or the at least one identification feature can be determined and assigned for each of the at least two Vehicles take place through the second control device by means of a second pictorial record.
  • the detection of the entry into the route section by the first control device and the detection of the exit from the route section by the second control device can include receiving an identification signal from a transponder from each of the at least two vehicles, which contains information about the at least one Has identification feature.
  • the detection of the entry into the route section and the detection of the exit from the route section can each include assigning a time stamp to each of the at least two vehicles.
  • a route transit time can be measured for each of the at least two vehicles and an expected value of the route transit time can be determined for each of the at least two vehicles.
  • the expected value of the transit time can be determined as a function of the type of vehicle, the permitted total mass or the permitted maximum vehicle speed.
  • the vehicles of the at least two vehicles whose route transit time is at least a first threshold below the expected value of the route transit time can be excluded from the entry sequence and the exit sequence for the detection of overtaking maneuvers.
  • the method for recognizing overtaking maneuvers can be temporarily suspended if, in a time interval, a minimum number of vehicles have a passage time that exceeds the associated expected value of the passage time by at least a second threshold value.
  • the at least two vehicles can be used depending on the vehicle type (for example by determining the size of the vehicles or identifying further vehicle features such as the vehicle brand) and / or the permitted Total mass can be categorized.
  • the at least two vehicles can be categorized by means of the first image recording and / or with laser scanners / lidars and / or on the basis of the information of the respective identification signal of the transponders of the at least two vehicles. This makes it possible for fines to be enforced only for vehicles of the vehicle class in question when there is a prohibition on overtaking for a certain vehicle class after the detection of overtaking maneuvers.
  • At least one of the first pictorial recording and the second pictorial recording can serve as a first pictorial evidence capture and / or a second pictorial evidence capture can take place in a direction of travel behind the second control device.
  • videos can be created at least from parts of the route section and, when overtaking maneuvers are recognized, associated sequences of the videos can be documented together with the overtaking maneuver
  • determining the entry sequence and determining the exit sequence can each take place for a vehicle group that enter the entry area and / or the exit area in a predetermined time window.
  • the time window can be determined as a function of the length of the route section and / or the volume of traffic. This can ensure that the computing capacity required for the respective determination of a sequence is limited.
  • provision can also be made for the entry and exit sequence to be determined as a continuous row and for overtaking maneuvers to be recognized for all of the vehicles.
  • a further possible embodiment of the method can provide that a vehicle speed of the at least two vehicles is determined during the detection of the entry into the route section and / or the detection of the exit from the route section.
  • the route section 3 is divided into a first lane 3a with the direction of travel T, on which the first vehicle 1 is located, and into a second lane 3b with a direction of travel T 'opposite to the direction of travel T'.
  • the route section 3 is delimited at one end by a portal 6 of a first control device 5 and at the other end by the portal 11 of a second control device 10.
  • the portal 6 is used for lane 3a as an entrance to route section 3 and for lane 3b as an exit from route section 3.
  • the portal 11 is used accordingly for lane 3a as an exit from route section 3 and for lane 3b as an entrance into section 3.
  • the first control device 5 detects the first vehicle 1.

  • on-board units 9, 14, also called transponders of the detected vehicles 1, 2.
  • all common systems for short-range communication can be used for radio-based detection.
  • the on-board unit 9 of the first vehicle 1 emits an identification signal to the transmitter-antenna unit 8 during the communication, which identification signal contains information about at least one identification feature of the first vehicle 1.
  • the at least one identification feature can be the vehicle registration number or some other vehicle identification number.
  • the identification signal can also contain information about the vehicle category, for example the type of vehicle or the permitted total mass.

It is also conceivable that the captured vehicles are categorized by evaluating the pictorial recordings, for example as a function of the vehicle type or the permissible total mass.
  • the graphic recording of the route section 3 and the associated automatic number plate recognition takes place in addition to the recording of the on-board unit 9. It is also conceivable that the vehicles are only detected by one of the recording of the on-board unit 9 or the graphic recording.
  • the cameras 7, 7' are aimed at a route area outside the route section 3 and the pictorial capture of vehicles outside the route section 3 takes place.
  • the second vehicle 2 then enters the route section 3 in the lane 3a.
  • the second vehicle 2 is driven by the first control device 5 detected by means of the camera 7 and the transmitter-antenna unit 8.
