Definitions

  • Traffic data acquisition and traffic regulation are due to the growing traffic has become indispensable.
  • DE-A-41 05 584 is a traffic information system became known, which is based on a Mobile communication system works. In doing so, one Central office traffic information about a Organization channel of the mobile communication system to the Vehicles transmitted, the information transmitted can then be displayed optically or acoustically in the vehicle can. It is also provided that information about the Location and / or the movement of the vehicle is detected will be forwarded to the central office. Becomes a cellular mobile communication system is used also a rough location of the vehicle based on its location in a specific radio cell possible.
  • the object of the present invention is a method and a facility for determining dynamic Propose traffic information, the above Avoids disadvantages and with moderate effort nationwide coverage the traffic data essentially directly from the Vehicle allowed out. This is supposed to be a comprehensive one Data acquisition system for traffic information created become.
  • current and historical traffic flow information such as the speed traveled, current traffic volumes, braking, etc. Acceleration behavior, traffic jam reports, accident reports, weather events etc., required on road sections.
  • This information is the basis for the qualitative and quantitative expansion planning of the transport network.
  • This information can be obtained from the vehicles via mobile radio.
  • it is necessary to provide a device for self-location in the corresponding vehicles.
  • predictable traffic algorithms for example vehicle-side and central-side recognition algorithms from these current traffic flow data, supplemented by historical values, to predict and determine their impact. In this way, traffic information can be updated very quickly, ie recognized or deleted.
  • the traffic flow data collected by vehicle terminals is transmitted to a regionally responsible service center.
  • traffic counts and speed determinations can be determined.
  • This "mobile traffic data generation” means that the expenses are significantly less expensive than conventional methods with fixed installations in or on the lanes.
  • the control of the traffic data acquisition on the vehicle side can be carried out by reaching virtual acquisition points, ie after the start of the journey, the process of the traffic data acquisition is only started after reaching a collection point.
  • Subsequent route-related detection processes are also controlled by reaching detection points. If a detection point that would have to be passed due to a previous route is not reached within a predetermined period of time, the system assumes the end of the journey or the leaving of the detection area (for example secondary roads) and the detection process is ended.
  • BAB federal highways
  • the position details of the accident location plus historical travel position data for determining the direction of travel are transferred to the mobile network using the fastest possible communication.
  • the data are then transmitted directly in the radio cell concerned or also in the neighboring radio cells to all accessible mobile radio subscribers without preprocessing.
  • the accident data are advantageously sent to the responsible person at the same time Service center transfer that a review / plausibility check who makes data. After review confirmation will be sent to the relevant mobile subscribers distributed or the accident report canceled. All that assumes that the respective cell phone subscribers have a Corresponding, suitable for receiving these messages Device.
  • a The vehicles are only reported back to the head office when one or more predefined events actually occurred are like Wiper actuation as a hint on the onset of rain or braking.
  • This feedback to the service center supplemented with the location and time of the occurrence of the event, the center arranges one Overview of the general traffic situation in the coverage area.
  • a memory-expandable information container of the signaling channel be used.
  • Such an information container is then in the responsible network node of the mobile network (e.g. the BSC of the GSM networks) and evaluated Broadcast functions in the relevant radio cells.
  • the end devices consist of a satellite-based navigation system, mobile radio communication functions and a module for the application function including the few required operating functions.
  • the application software and operating data can be introduced into the vehicle-side terminal via a chip card, separate mechanical interfaces or via mobile radio interfaces.
  • the necessary configuration parameters to record the dynamic Traffic information or traffic events are also sent by chip card (e.g. by post) mechanical interfaces, via individual point-to-point or distribution communication set in the terminal.
  • the application recognizes whether the vehicle 13, which is located on a traffic route 12, has passed through a defined detection area S1 and determines the transit time to the detection area S2. If the specified transit time is significantly exceeded, the route section defined by the detection areas S1, S2 and the actual transit time are coded as "floating car data" and optionally with additional vehicle-side additional information, such as the operating status of brake lights, rear fog lights, windshield wipers, ABS etc., and via mobile radio transmitted to the acquisition center 20 (see FIG. 1). The speeds of the vehicles determined by the vehicle terminals are then assigned to the road sections on the basis of this assignment. In the same way, simple counting of the vehicles or the detection of traffic flows through a certain section of the route defined by detection areas S3, S4 is possible. Braking and acceleration behavior of the vehicle is recorded as event-related information and transmitted to the control center with position and time data.
  • FIGS. 5 and 6 show, the position of the detection areas is S1, S2 are initially fixed. But you can at Occurrence of a traffic-relevant event (congestion area 14) are dynamically varied to S1 ', S2' and so to the new traffic situation be adjusted so that the best possible Data collection is guaranteed.
  • event 14 the terminal recognizes this from the vehicle behavior (braking) of the vehicle in the affected detection areas (S1, S2 or S1 ', S2') and a message is sent to the control center 20 via mobile radio.
  • Abrupt standstill of the vehicle can be an indication of an impact or accident. Braking the vehicle hard on the freeway often means that traffic jams begin. Slow travel gives an indication of heavy traffic, etc.
  • This message is coupled with the information about where the event occurred (eg intersection 17) and the position of the reporting vehicle (e.g. route intersection 18 - intersection 17).
  • the information given to the control center 20 would therefore be, for example: Event 14 occurred at intersection 17 after the travel route intersection 18 - intersection 17.
  • the control center 20 can now output to all vehicles the information that when crossing the route section 18- Junction 17 event 14 (traffic jam) will occur.
  • the route junction 18 - junction 19 is named as a possible alternative. If the alternative route is removed from the vehicle, the central unit 20 receives feedback. From the vehicle feedback, the central unit 20 can recognize whether the diversion recommendation is accepted.
  • the received data are processed by the application function in the control center 20 and the route data are assigned to a digital road map in a dynamic database 7.
  • the geographical self-location in the vehicle can be used to draw attention to the impending end of the traffic jam, for example, just before the traffic jam (warning: danger of collision).
  • the receivers 13a, 13b, 13c with a corresponding terminal device be equipped.
  • the accident data taken as an example, e.g. Accident position, with your own vehicle position compared. Will relevance (approach to the accident site) recognized, this is done via a human-machine interface communicated. This can be done visually and / or acoustically (e.g. "Accident after 2.5 kilometers").
  • the distance information are using the on-board satellite-based navigation system updated.
  • the confirmation or cancellation the traffic report by the service center 20 accordingly acoustically / visually displayed.
  • the data is transmitted, for example, via a Signaling channel of the GSM mobile radio network available throughout Europe.
  • a digital street map of the detection area is located in the control center 20 in the granularity of the road classes (BAB, Federal highways, district roads, city and. Municipal roads) and with system-specific attributes of the individual route sections (such as average transit time, parking spaces, etc.).
  • BAB Federal highways, district roads, city and. Municipal roads
  • system-specific attributes of the individual route sections such as average transit time, parking spaces, etc.
  • FIG. 1 explains the functions that the control center 20 should preferably take over.
  • the control center 20 takes over the communication management for the incoming dynamic traffic flow information of the various terminals (EG, 1, 2, 3), which are each equipped with or without a digital road map.
  • the data of existing, conventional detection systems, for example of induction loops 4, can likewise run into the control center 20.
  • Communication with the end devices (EG) takes place, for example, via a GSM network, for example the D1 network.
  • the information received is recognized in a special communication server 5, processed and stored in a service server 6 for further processing, and 7 route segments are assigned in a database.
  • the plausibility check 8 and a comparison are carried out using the traffic flow information obtained via roadside infrastructure systems 4.
