Definitions

  • the invention relates to a control arrangement for traffic signals, according to the preamble of claim 1, with which in particular a special state of the traffic signal, for example a green phase of a traffic light, can be switched for an emergency vehicle.
  • a special state of the traffic signal for example a green phase of a traffic light
  • Such a control arrangement is known for example from DE-OS 28 55 625.
  • a signal is sent from a transmitter unit attached to the emergency vehicle and transmitted to a receiver unit.
  • the transmitter unit on the vehicle is triggered by a radio beacon, and the location identifier of the radio beacon is transmitted together with other data to the stationary receiver unit.
  • radio beacons and the associated receiving systems are susceptible to interference.
  • the radio beacons - especially battery-operated radio beacons - are regularly not vandal-resistant.
  • the vehicle-side receivers assigned to the radio beacons are also relatively sensitive. For example, when using gun diodes due to reflections from other vehicles, etc., multiple reception signals cannot be completely ruled out, so that the address of the radio beacon in question may be transmitted incorrectly.
  • DE-OS 28 55 625 provides for the input sensitivity of the vehicle-side receiver to be greatly reduced in order to exclude external signals.
  • this measure requires an increased transmission power of the radio beacon, which makes the desired battery operation of the beacon more difficult and more expensive.
  • Another problem with this solution is the distance between the beacon and the traffic signal. If the distance is chosen to be comparatively large, it is certain to be sufficient
  • red phase of the cross traffic could be interrupted and switched to a green phase depending on the time using a "safety circuit".
  • safety circuit there is then the danger that this will happen at a time when the emergency vehicle is approaching the traffic signal system in question.
  • DE-AS 28 50 208 it is therefore known from DE-AS 28 50 208 to include the speed of the vehicle in the data to be transmitted to the traffic signal system.
  • this solution it is possible to reduce the number of signaling stations, so that the risk of damage, as is the case with radio beacons, is significantly reduced.
  • a disadvantage of this solution is that it can basically only be implemented in the case of intersections which are relatively straight and clearly arranged. The combination of reporting stations in the intersection area does not always allow sufficient time for the intersection to switch to the preferred direction, and two accidentally driving emergency vehicles can only be separated - if at all - only with special circuitry work to prevent that Passing the first vehicle the red phase is initiated at this point.
  • the invention has for its object to provide a control arrangement for traffic signals according to the preamble of claim 1, which is more reliable and already less susceptible to failure from the basic concept, without the adaptability would be restricted to different local conditions.
  • the serial that is to say transmission of, location data in chronological order
  • accurate and appropriate information can be provided for the assessment of the optimum switch-on time for the green phase for the emergency vehicle.
  • the installation effort is nevertheless less than, for example, in the case of a system with radio beacons, even though these only allow a specific status information of the emergency vehicle.
  • the serial transmission of location data not only enables direction detection, that is, the unambiguous assignment of the emergency vehicle to the traffic route from which it approaches the traffic signal system, but also, in an advantageous embodiment, the detection of the expected time of arrival.
  • the location data can be transmitted, for example, in a fixed time grid, so that the difference between the transmitted coordinates corresponds to the speed of the vehicle.
  • the system according to the invention thus makes it possible not only to distinguish between 2 basic directions at a conventional intersection, but also between a total of 4 approach directions, so that, for example, separate lanes for left-turners, right-handers and for straight-ahead traffic, secured with light signals from the traffic signal system, can be distinguished from the Approach direction of the emergency vehicle, all possible light signals can be switched to "green phase".
  • control arrangement according to the invention for different types of traffic signals. For example, when a bus stop is approached by a bus, the stop in question could be signaled therein, and at the same time the corresponding lane of the bus can be activated.
  • the switchover of the traffic signal system to the green phase is prepared gently in the desired direction, that is to say without an abrupt disturbance in the cyclical light signal sequence.
  • the expected arrival time of the emergency vehicle is calculated on the basis of the transmitted coordinate information and continuously adapted to the new measurements as it passes through the standby zone.
  • the green phase is then optimized in such a way that it begins at a point in time corresponding to the maximum assumed speed of the emergency vehicle, the red phase for the transverse and oncoming traffic strands having been initiated at a sufficient interval before this point in time.
  • location data patterns with a certain variance are stored in the read-only memory of the traffic light computer, which is used as a basis for comparison for the location data patterns. If, for example, a location data specification is made to within 4 bytes, only the most significant 3 bytes can be used for evaluation by the comparator unit, so that, for example, a lane deviation of the emergency vehicle, which in the example case can also extend over more than 10 m, is not taken into account.
  • the location data pattern detection according to the invention ensures that non-faulty location data patterns, which originate, for example, from a transversal emergency vehicle that does not even approach the traffic signal system in question, but passes it laterally, is erroneously used as an activation signal be interpreted.
  • the coordinates detected by the traffic light computer may correspond exactly to the target coordinates for triggering an activation of the traffic signal.
  • the following location data diverge greatly from the target data due to the transverse movement of this emergency vehicle, so that the initiation of an activation phase or a special state is prevented.
  • the control arrangement in an emergency vehicle has a transmitter unit 10 for location data.
  • This location data is received via a GPS receiver 12, processed in a control unit 14 and fed to a FIFO memory 16.
  • the FIFO memory 16 transmits the data in succession to the transmitter unit 10, which it transmits via an antenna 18 on the vehicle.
  • the GPS receiver also has an antenna 22 and operates in the frequency range of approximately 1.5 GHz, while the transmitter unit operates in the range of approximately 80 MHz. It goes without saying that the frequencies can be adapted to the requirements in a wide range. Basically, it is provided that the transmitter unit 10 has a range of 1 to 2 km even in built-up areas in order to leave enough time for the preparation of the activation of a special state of a traffic signal.
  • the control unit 14 and the FIFO memory 16 are part of an on-board computer 24, which also has a data processing unit 26, which processes the data from the control unit 14 and adjusts it for transmission to a display unit 28.
  • the actual transmission takes place via an interface 30, which is between the display unit 28 and on-board computer 24 is switched.
  • the display unit 28 has an input unit such as a keyboard 34.
  • the display unit 28 shows in a schematic form the traffic signal systems to be passed and shows the current position of the vehicle and the direction of movement of the vehicle on the screen.
  • the feedback channel 38 is also connected to the antenna 18 and has a feedback receiver 40, the output connection of which is connected to the data processing unit 26.
  • the feedback channel operates essentially in the same frequency band as the transmitter unit 10.
  • FIG. 2 shows the fixed part of the control arrangement, which is attached in the immediate vicinity, that is to say in or on the traffic signal system, which is symbolically represented with the traffic signal 42 in FIG. 2.
  • a receiver unit 44 is provided in a fixed position, which is connected to an antenna 46 and receives the signals of the antenna 18.
  • the receiver unit is connected to a comparator unit 48, and either in the receiver unit 44 or in the comparator unit 48, if necessary, an analog / digital conversion takes place if the location data patterns have been transmitted in analog form.
  • the comparator unit 48 has a second one Input connection, which is connected to an electrically erasable read-only memory EEPROM 50.
  • the EEPROM 50 contains all possible data patterns which represent an approach of an emergency vehicle in one of the four possible directions of approach, it being understood that a certain tolerance has been built in deliberately.
  • the output of the comparator unit 48 then emits a signal which triggers the special state and only when the location data pattern corresponds to a location data pattern in the EEPROM 50 which indicates that the emergency vehicle is approaching. Only in this case is the cyclical light signal sequence of the traffic signal 42 intervened and the special state is softly initiated via a traffic light control unit 52. At the same time, a confirmation signal is sent via the feedback channel 38, which indicates that the special condition is being initiated.
  • the feedback channel 38 has a feedback transmitter 54 in the fixed area, which is also connected to the antenna 46 and is connected to the feedback receiver 40 via this.
  • the comparator unit 48, the traffic light control unit 52 and the read-only memory 50 are part of a traffic light computer 53.
  • the feedback channel is not absolutely necessary for the operation of the system.
  • the display unit 28 does not always have to be able to display the relevant "map" of the surroundings. Even if the environment is not programmed, the current coordinates can always be faded in via the display unit 28, so that the risk of the procedure for the emergency vehicle is greatly reduced even in an unknown area. With appropriately equipped traffic signal systems, emergency vehicles can be exchanged between different cities, so that there is compatibility.
