Definitions

  • Examples of such devices are traffic light monitoring systems or photographic speed monitoring systems operating with Doppler radar.
  • a sensor such as an induction loop installed in the road, gives a signal when a vehicle enters an intersection monitored by traffic lights. Another signal is provided by the traffic light when the traffic light goes into its blocking phase. If the vehicle enters the intersection during the blocking phase, a photograph is taken, which records the vehicle and its license plate. This enables the vehicle to be identified and the violation to be documented. In order to improve the evidential value of the photographic registration, several shots are usually triggered one after the other.
  • the already mentioned AT-PS 225 077 describes, in one embodiment, a traffic monitoring system with two sensors arranged at a fixed distance from one another in the paint path. A camera is triggered and the vehicle is photographed when the time interval between the two sensors being passed is less than a predetermined value.
  • a similar arrangement is given by the AT-PS 246 617 known.
  • sensors for traffic counters e.g. in the form of induction loops in the carriageway and the number of vehicles passing through for statistical purposes.
  • the invention is based on the knowledge that, in traffic monitoring systems of the type mentioned above, a large amount of information about the traffic situation is obtained as "waste products", which are interesting for traffic planning and traffic statistics and possibly also for the assessment of a single registered violation, but which are not recorded in the known systems.
  • This information is particularly interesting because such traffic monitoring systems are usually used at traffic foci where statistical documents on traffic density, temporal distribution of traffic and frequency of violations of traffic rules are of particular importance for traffic planning and control.
  • the invention is accordingly based on the object of making it possible to use such additional information which is obtained in traffic monitoring devices.
  • the invention is further based on the object of facilitating the evaluation of the detected violations by means of electronic data processing.
  • this object is achieved by an electronic memory in which processes recorded by the device can be stored for later evaluation.
  • the vehicle density can therefore be determined and, with the help of the clock and date provided anyway, the temporal distribution of the vehicle density can also be determined.
  • the number of violations can be related to the vehicle density, or the time distribution of the violations can be determined. If the device can differentiate between cars and trucks based on a histogram, then this can also be statistically evaluated.
  • the statistical analysis can also be used to draw conclusions about the traffic situation at the time of a particular violation. For example, one can determine whether there was heavy traffic or the road was empty during the period in which, for example, a monitored vehicle was driving at excessive speed.
  • the electronically stored data of the detected violations can also be used to, for example, the form with the help of electronic data processing moderate processing (writing an advertisement) of the registration. Then only the stored data (e.g. date, time, location and speed) need to be identified by a number that also appears on the recording. The evaluating official only needs to enter the vehicle registration number recognizable in the recording in a form which has been filled or written by a computer after the memory. This can significantly relieve the police of routine paperwork.
  • Embodiments of the invention are the subject of the dependent claims.
  • a sensor 16 in the form of an induction loop is embedded in the road surface of a road 14 leading into the intersection just before the intersection with the intersection 10. The sensor 16 responds when a vehicle 18 drives over it.
  • a device 18 for photographically monitoring the intersection 10 is arranged in a housing 20 which is arranged on a column 22 at a short distance from the intersection 10.
  • the device 18 includes a signal processing unit 24, a photographic camera 26 controlled by the signal processing unit and a flash unit 28.
  • the signal processing unit 24 receives a sensor signal from the sensor 16 via a line 30 and a blocking phase signal from the traffic light 12 via a line 32 when the traffic light switches to blocking phase.
  • the traffic light 12 contains a transmitter 34 which supplies the blocking phase signal.
  • the signal processing unit 24 supplies a trigger signal to a camera trigger 36 if a sensor signal appears during the blocking phase.
  • the camera trigger 36 then triggers the camera 26.
  • the camera then takes a picture of the intersection 10 with the traffic light 12 on the blocking phase and the vehicle 40 (FIG. 1) which has triggered the sensor signal.
  • a clock 42 and a date generator 44 provided. These form means 46 for generating time information.
  • the displays of clock 42 and date generator 44 are reflected in the recording or otherwise recorded on the film.
  • a memory 48 is now provided.
  • the processes recorded by the device can be stored in this memory for later evaluation for statistical purposes.
  • the sensor signals from the sensor 16 can be applied via a line 50. These provide the total number of all vehicles that entered the intersection, regardless of whether they entered the intersection during the blocking phase and were photographed or not. This information is lost in conventional devices of this type.
  • the memory 48 also receives the signals from the signal processing unit 24 via a line 52, through which the camera trigger 36 is controlled. These signals provide the number of violations detected. Finally, the memory 48 also receives time information from the clock 42 via a data line 54 and from the date generator 44 via a data line 56.
  • the memory can be part of a microprocessor, in which the information is classified, so that the number of events received in predetermined time intervals (pulses on lines 50 and 52, respectively) is stored together with the associated time information (time and date).
  • the traffic density in the street 14 can be determined as a function of time. It can be determined what the ratio of the number of violations to the total number of vehicles driven is and whether this ratio changes with time or with the vehicle density. It can also be determined what influence traffic light settings, for example an extension of the "yellow phase", has on the absolute or relative number of registered violations.
  • the stored data of various devices of the present type arranged at traffic hotspots of a city provide a continuous overview of the traffic events in the city and thus documents for traffic planning. All of this is achieved using existing components with a relatively small additional effort.
  • the device 58 is arranged laterally from a street 60. 62 denotes a vehicle to be monitored.
  • the device 58 contains a radar antenna 64 which emits a "radar lobe" 66, which is shown in broken lines.
  • the "radar lobe” represents the emitted radiation energy per solid angle as a function of the angle.
  • the device 58 also contains one photographic camera 68 that captures a field of view 70.
  • the signals of the radar antenna 64 are connected to a measuring and evaluation circuit 72.
  • the measurement and evaluation circuit provides speed measurements when the vehicle 62 passes through the radar lobe.
  • the camera 68 is triggered when a permissible maximum speed is exceeded. It is triggered at a point in time at which the vehicle 62 is essentially in the middle of the field of view 70 of the camera 68.
  • Information provided by the measurement and evaluation circuit including the number of vehicles passing through (regardless of whether it is too fast or not), is stored in a memory 74 for later statistical processing.
  • the device 58 is shown schematically as a block diagram.
  • a Doppler radar 76 which comprises the radar antenna and the associated transmitting and receiving device and an evaluation circuit, provides measured speed values.
  • the speed measurement values are processed into a histogram, that is to say a distribution of the frequencies of speed measurement values over different speed classes. Overtaking processes or the like can be made from this histogram. can be recognized, which could lead to incorrect measured values, so that measured values obtained in this way are suppressed and do not lead to the camera being triggered. It can also be recognized whether the detected vehicle is a car or a truck. And the histogram results in a measured value for the speed of the monitored vehicle 62. In FIG. 4, the evaluation "car / truck" is symbolized by a block 80.
  • the determination of the speed from the histogram is represented by a block 82.
  • the evaluation "car / truck” controls a comparator 84 or 86.
  • On the Comparator is the measured value of the speed of vehicle 62 from block 82 and is compared in each of the comparators with a permissible maximum speed predetermined for the type of vehicle in question, for example of 120 or 80 km / h.
  • a trigger signal is given to a camera trigger 88 at a measured value of more than 120 km / h or a measured value of more than 80 km / h.
  • the camera trigger 88 then triggers the camera 68.
  • the time then taken from a clock 90 and the date from a date generator are simultaneously reflected in the recording that is then made.
  • the various information accumulating in this device are transferred to the memory 74.
  • the memory 74 receives the time from the clock 90 via a data line 94 and the date from the date generator 92 via a data line 96.
  • the memory 74 receives the measured value of the speed from block 82 via a data line 98.
  • the memory 74 also receives Pulses from the evaluation "car / truck" 80 depending on whether a car or a truck is detected via line 100 or 102.
  • the memory 74 receives pulses from the comparators 84 and 86 via line 104 or line 106, if a vehicle has exceeded the permissible maximum speed specified for his vehicle type and a triggering pulse is given to the camera trigger.
  • the events can also be summed and classified according to speed and / or time.
  • the information about non-photographed vehicles is also a "waste product" and can be relative little effort can be recorded and statistically evaluated. Of course, it is not necessary to save all the information given here if not all of this information is to be evaluated.
  • the statistical evaluation can also be important for the assessment of a single, recorded violation. For example, exceeding the speed limit can be more or less serious depending on whether there was heavy traffic at the time or the road was almost empty.
  • the electronic storage of the data associated with a recorded violation of the traffic rules can be used to relieve the police when dealing with the violations found. This is because the data stored in the electronic memory can be used to fill out or create forms for a notification or a fine notice by means of a computer. These forms then contain the date, time, place and type of violation from the memory. The police need only enter the vehicle registration number in such a form from the photograph.
