Definitions

  • the invention relates to a mobile traffic monitoring system with a device for monitoring traffic flows by means of optical devices in the vehicle according to the preamble of claim 1.
  • a photographic camera for traffic monitoring has become known from DE 11 39 315, in which two cameras installed with different angles of view are integrated in the vehicle to record the traffic situation, one of the cameras recording the driving speed and the time. This is a control and monitoring device used by the police to record speeding violations. These and the numerous similar facilities also do not indicate that the vehicle driver should be given a quasi-personal documentation device for the automatic detection of accident-prone situations.
  • a method for measuring the flow of traffic and the classification of the individual vehicles on roads has become known from DE 38 30 598 - C2, in which different sensors deliver identification signals which are compared and evaluated with stored characteristic data.
  • the method is not used to document situations in the traffic of the "own" vehicle.
  • UDS accident data recorders
  • the present invention has for its object to provide a mobile traffic monitoring system of the type mentioned, which is integrated in the vehicle and automatically compares the functional devices carried out in chronological order with the simultaneous traffic events and the possible traffic situations together with the in and on the vehicle records the device actuations taken in documentary form.
  • the proposed mobile traffic monitoring system will be explained using the example of a local public transport bus. It consists of three components: image acquisition system, status data storage and sensors. The recording and image acquisition system is coupled with functions of the bus operating instruments and is only activated in very specific situations. The situation described below is explained as an example:
  • a bus drives to a marked public stop and certain instruments of the vehicle are actuated, such as the direction indicator (turn signal), the brake and the door opener.
  • This defined operating status is now stored in the present monitoring system and, at the same time, a camera in a defined position is made available for taking a picture.
  • the camera is preferably already installed and positioned accordingly in the vehicle interior. If the left turn signal for threading into the flowing traffic is set when the vehicle is started again, and an overtaking vehicle passes sensors a, b on the bus, for example inductive sensors, radar, light barrier, etc., the recording device integrated in the vehicle, e.g. camera, Video or film device activates and creates a situation picture or film. It is essential that the instantaneous status of the control elements is stored simultaneously with the image triggering, that is to say the situation and vehicle operating state are saved together and simultaneously. The situation in the image or film and the vehicle operating status are therefore stored in the data carrier.
  • the so-called image memory - i.e. the camera or video film - is immediately available for a new situation after the automatic film transport, but can be used at any time for evaluation, but at the latest when the image carrier is fully exposed.
  • the data carrier is also "synchronously rewound" with the image carrier, so that the recording and associated situation data are virtually congruent from case to case.
  • the memory content is generally only committed in the event of a "crash", but that in an extended embodiment it is also possible to record dangerous traffic situations in connection with the vehicle (here the public bus), in particular in the event of violations of existing laws.
  • the vehicle here the public bus
  • FIG. 1 and 2 illustrate a situation in which a public local bus enters a stop and actuates the brake light.
  • a public local bus enters a stop and actuates the brake light.
  • the vehicle brake When the vehicle brake is actuated, not only do the brake lights light up, but the camera integrated in a special position on the vehicle is also "made ready" for a recording (or scene film). If - despite the prohibition - a vehicle now passes a sensor activated by the bus brake light - which can be designed, for example, as a light barrier - the camera image trigger is activated at the same time and the dangerous traffic situation from the point of view of the bus is captured in the image. This also proves that the taillights, indicators, etc.
  • start-up control not only to record the setting of the turn signal, but also all other actuation information for the vehicle, i.e. closing the doors, engine speed, etc.
  • a commercially available automatic camera i.e. with automatic or preset aperture / time combination and fixed distance setting - with a film transport motor is sufficient for the image acquisition.
  • a commercially available automatic auto focus camera can also be used. If the bus now goes out of the bus stop onto the normal lane and sets the left turn signal for this purpose, the camera automatically pans outwards in order to detect traffic overtaking (Fig. 4 and 5) and "lane cutter". The angle of view of the lens can also be increased by setting the turn signal, if the camera is not equipped with a wide-angle lens from the outset.
  • the overtaking vehicles can be picked up in or against the direction of travel.
  • the sensors a, b which initialize the image acquisition and storage, are defined in the order to be traversed - as illustrated in FIG. 3 - that is, a to b or b to a. Otherwise vehicles of the opposite direction pass through the sensors a, b can also be recorded.
  • the above-described vehicle-integrated image and data storage device only delivers a status report for two road users who are independent of one another but are in a traffic situation that is dependent on one another.
  • the sensors (a, b) are also defined in their sequence to be traversed, so that e.g. no vehicles in the opposite direction are detected.
  • the data storage device provides the status of the functional elements such as indicators, door position or speed, etc. of the vehicle in which it is integrated at the time of the "hazard" or "crash".
  • the combination of the externally and internally functioning elements provides documented information about the relevant time-related traffic flow, and completely independent of time, location and technical conditions.
  • the single image recording or video camera can be permanently installed on the vehicle at a defined location, but can also be designed to be automatically retractable into the vehicle body.
  • the sensors that trigger the camera and memory impulses are defined in the order to be passed.
  • the focal length is set, for example, via the turn signal system of the vehicle.
  • the lens is automatically set to "wide angle" by a switching element of the turn signal system and, for example, automatically to a normal focal length (50mm) by an element of the gear shift.
  • a switching element of the turn signal system for example, automatically to a normal focal length (50mm) by an element of the gear shift.
  • 50mm normal focal length
