Definitions

  • the invention relates to an accident-related control of a traffic signal system, for example a traffic signal system.
  • the invention relates to the field of regulating individual traffic by means of traffic signal systems, in particular the regulation of road traffic by means of traffic light systems (LSA) at road junctions.
  • LSA traffic light systems
  • a signal sequence of a traffic signal system follows a predefined control.
  • This control is usually composed of different phase states, the transition of which is controlled by time and / or traffic dependencies.
  • a phase state defines the entire signaling at the traffic signal system, in a traffic signal system at an intersection, for example, the illumination or flashing of red, yellow and / or green for each direction.
  • the individual traffic routes are released or blocked.
  • the timing i. the temporal relationship
  • the phase states of a signaling system can also be represented as a signal plan.
  • the recording of a signal plan makes it possible to follow the processes at the signal system as a function of time or traffic volume.
  • a disadvantage of the prior art is that the detection of an accident event is not used locally on the signal system. Thus, assistance is called, but not contributed to the fact that the accident can be reproduced or reconstructed. For this one is then dependent on testimonies whose reliability and accuracy is sometimes unclear, and which may even contradict each other. This makes it at least difficult to clarify the accident circumstances. In particular, according to experience, it often remains unclear how the accident event is related to the signaling by the signal system, whether the signal system was disturbed, for example, and thus possibly (co-) caused the accident.
  • the invention is based on the object to enable an accurate and reliable reproducibility of operation of a signaling system in connection with a vehicle accident.
  • the object is achieved with a method according to claim 1, a controller according to claim 11, a traffic signal system according to claim 19 and a computer program according to claim 20.
  • the invention solves the problems of the prior art such that a reproduction or reconstruction of an operation of a traffic signal system or of a vehicle accident in the area of this traffic signal system is made possible with regard to the exact time and current state of the traffic signal system. With In other words, a traffic light circuit can be accurately reproduced at the time of the accident.
  • vehicle accident here includes both an accident between several vehicles, including vehicles of different types such as cars, motorcycles or bicycles, as well as an accident in which only one vehicle is involved, e.g. a collision of a vehicle of any type with a pedestrian or fixed equipment such as the signaling system itself.
  • operating conditions of a signaling system are secured after detection of an accident event, i. documented.
  • an accident event i. documented.
  • they can be used in an advantageous manner to clarify the accident circumstances in connection with the operation of the signaling system.
  • a position of an injured vehicle is determined and signaling is controlled according to the position of the injured vehicle.

  • the detection device 102 is provided with a receiving device 106 and / or with a e.g. a video camera having a video capture device 107 connected.
  • the detection device 102 is set up to detect an accident event, ie that a vehicle accident has occurred in the area controlled by the signal system (eg an intersection). This detection is carried out according to one aspect of the invention on the basis of accident information transmitted from an accident vehicle KFZ (eg by radio signal / transmission pulse) and received by the receiving device 106.
  • accident information from a communication between signal system LSA and vehicle motor vehicle may include information about an activation of a sensory device on the vehicle, for example of airbag, belt tensioner or vibration meter. They may also include information about activation of a manual device on the vehicle, eg pressing an accident or emergency button by a vehicle occupant.
  • the activation of one of these devices can in turn trigger the transmission of corresponding accident information to the nearest signaling system LSA.
  • the signal system is aware of the fall and the detection device 102 can then detect the presence of an accident event.
  • This detection is carried out according to a further aspect of the invention optionally or additionally on the basis of image data, ie image material of the affected area (eg crossing), which are generated by the image capture device 107 to the signal system LSA.
  • image data ie image material of the affected area (eg crossing) at the detection device 102, the presence of an accident event can thus be detected in the same way or in addition.
  • FIG. 2 shows an exemplary accident situation at an intersection, where a signal-equipped with signal technology signaling system is used according to one aspect of the invention.
  • the areas covered by cameras are illustrated by the intersection of borders.
  • the intersection interior is also detected by the cameras of the image capture device 107.
  • the crossing area can be fused and evaluated via the cameras into an "information image", ie a representation of the totality of available information
  • the detection device 102 records an accident event, for example on the regulated intersection, this is reported to the determination device 103, which causes it to determine the exact accident time.
  • This accident time determination is made clearly with reference to a reference time standard.
  • the time reference DCF77 or the time used by GPS ("Global Positioning System") or any other unique reference time standard may be used as the reference time standard.
  • GPS Global Positioning System
  • any other unique reference time standard may be used as the reference time standard.
  • the safety device 104 secures or documents time-corresponding operating states of the signal system LSA.
  • This can include a storage of the detected accident time, a current signaling state of the signaling device 101 at the detected accident time and / or a previous signaling sequence of the signaling device 101 prior to the time of the accident in a memory device 104A of the security device 104.
  • elapsed LSA signaling states can also be stored, for example the last n signal cycles prior to the detected accident event.
