Definitions

  • the present invention includes a method of control a system of multiple traffic signals to control the Traffic of vehicles, whereby a detection by the vehicles of traffic data.
  • the traffic data will at least partially by radio to traffic data processing devices transmitted in the traffic data processing facilities there is an analysis of the traffic situation, and on the basis of the result of the analysis, control of the Traffic signals carried out.
  • the invention further comprises an arrangement for controlling a system of several traffic signals based on traffic data generated by vehicles be captured with traffic data processing equipment.
  • the system includes transceivers that connected to the traffic data processing devices are as well as facilities for analyzing the traffic situation in the traffic data processing facilities and facilities to control traffic signals based on the result of analysis.
  • Such a method is, for example, from DE 196 01 024 for controlling traffic lights as a special type of traffic signal known. It describes that traffic data, in particular Position data determined by GPS, by mobile radio transmitted from vehicles to a central traffic control computer, local traffic control computer for data acquisition can be interposed.
  • the central traffic control computer conducts a central analysis of global Traffic situation for the entire system of traffic lights through and Coordination takes place based on the result of the analysis the local traffic control computer, which in turn is the individual Control traffic lights. It can also through the traffic control calculator Information on assistance to vehicle occupants be transferred to the vehicle.
  • the object of the present invention is therefore one possibility to control a system of multiple traffic signals provide that in the simplest possible way can be realized and still as comprehensive as possible Recording of the traffic situation and adaptation of the control allowed to the traffic situation.
  • This task is solved by the features of claims 1 and 10. Advantageous Further developments can be found in the dependent claims.

  • the traffic data via radio to each individually assigned to a locally limited group of traffic signals Traffic data processing equipment transmitted and takes place in every traffic data processing facility an analysis of the local traffic situation for the area the assigned locally limited group of traffic signals up to a maximum of neighboring locally limited groups of traffic signals.
  • a locally limited group of traffic signals can pass through one or more traffic signals are formed. Will the Group is formed only by a single traffic signal the local limitation is already caused by the traffic signal itself given. However, the group is characterized by multiple traffic signals the local limitation of the group is formed by the mutual functional dependency of the traffic signals defined. For example, at an intersection in usually more than one traffic light installed. Usually is at least one traffic light per direction of travel is provided. This However, traffic lights cannot be switched independently rather, they show a mutual functional Dependence on. So only certain directions of travel can one intersection must be released at the same time, others must be locked during this time. All traffic lights of one Intersection therefore form a locally limited unit of Traffic signals, their switching cycles in mutual functional dependency. The like can e.g. For successive speed limits or no overtaking apply along or along a section of road Signaling devices on railway lines or waterways, where the signal state of a traffic signal is mandatory the signal state of another traffic signal and such a comparable mutual functional dependency the traffic signals arise.

  • Such a decentralized one Process can be done through simpler, decentralized processing facilities will be realized. Also the susceptibility to errors of such a decentralized system is less because if one processing device fails, only a local one System failure results, in contrast to the risk of Failure of the overall system, as in the prior art can occur.
  • an analysis can also be provided the local traffic situation within an area takes place, which extends over the reception area of a transceiver of the traffic data processing equipment extends beyond.
  • the necessary for the analysis Traffic data from the sending vehicles via further transmission / reception devices to the transmission / reception devices of the traffic data processing equipment forwarded.
  • ad hoc network in which all Transmitting / receiving devices of the network as network nodes Forwarding of information to be transmitted used can be. Every transceiver can therefore also act as an intermediary.
  • Such networks can ideally through suitable design of the transmitting / receiving devices self-organizing.
  • the one for forwarding serving transceivers can either be installed in vehicles or stationary.
  • traffic data e.g. over several network nodes (Multi-Hop) to traffic data processing equipment be forwarded by vehicles outside the reception area the transceiver of the traffic data processing devices come. It can be on this Way even a data exchange between several locally limited Groups of traffic signals can be realized by the for controlling traffic signals or for local analysis the traffic situation can be helpful.

  • Provision can also be made for an acquisition and / or a transmission of certain or all relevant Traffic data of a vehicle to a traffic data processing device is triggered when the vehicle is a defined position, i.e. a kind of virtual position sensor, reached.
  • This defined position is indicated by the corresponding one Traffic data processing device set and the corresponding information is radioed to at least to transfer a vehicle.
  • the vehicle can then be carried on board Positioning devices such as wheel sensors, GPS or similar determine whether it reaches the defined position has and if there is agreement between the defined Position and the current position with the capture and / or the transmission of traffic data begin.
  • the defined one Position can be dynamically dependent in particular be determined by the current traffic situation.
  • Alternatively or in addition to the aforementioned method can be provided by all vehicles at all times a transmission of certain or all relevant traffic data takes place and in the traffic data processing facilities a processing of all traffic data received for Analysis of the local traffic situation is carried out. So it can e.g. only part of the traffic data depending on the Position of the vehicle is recorded and / or transmitted, other traffic data, however, can constantly and independently from defined vehicle positions. It can but also basically based on position-dependent detection and / or transmission can be dispensed with.

  • driver assistance information is included understand such information that the driver additional Information for the management of his vehicle and / or the Give an assessment of the traffic situation.
  • vehicle control information can, however, go directly to the operating state and the control of a vehicle intervened such as by automatically reducing the Vehicle speed when approaching a red traffic light or to an ambulance.
  • Another object of the present invention is a Arrangement for controlling a system of several traffic signals based on traffic data captured by vehicles become.
  • the arrangement comprises traffic data processing devices as well as transmitting / receiving devices, connected to the traffic data processing equipment are.
  • the arrangement also includes devices for Analysis of the traffic situation in the traffic data processing facilities and finally control devices the traffic signals based on the result of the analysis.
  • individually a locally limited group of Traffic signals a traffic data processing device is assigned and each traffic data processing device to analyze the local traffic situation for the area the assigned locally limited group of traffic signals up to a maximum of neighboring locally limited groups is trained by traffic signals.
  • a locally limited group of traffic signals can also are formed here by one or more traffic signals. If the group is formed by only one traffic signal, So the local limitation is already due to the traffic signal given yourself. However, if the group is made up of several Traffic signals formed, so the local limitation of the Group also for this subject of the invention by the mutual functional dependency of the traffic signals defined. Again, reference is made to the fact that usually at least one traffic light at each intersection per direction of travel is provided, which is not independent of each other can be switched. Rather, they have one mutual functional dependency on, as already above executed. All traffic lights of such an intersection form a locally limited unit of traffic signals whose Circuit cycles in mutual functional dependency stands. The same can be said for this subject of the invention e.g. for successive speed limits or overtaking bans along a section of road apply or for signaling devices on rail routes or Waterways where the signal state of a traffic signal imperative the signal state of another traffic signal conditional and so a comparable mutual functional Dependence of the traffic signals arises.
