Definitions

  • the invention relates to a method for recording data about the traffic situation in a road network according to the preamble of claim 1 and to a corresponding device according to the preamble of claim 11.
  • Traffic data collection and traffic regulation have become essential due to the growing volume of traffic.
  • Methods are known for traffic data acquisition, which use stationary detection sensors.
  • the current traffic information for example by induction loops, infrared sensors, camera surveillance on bridges or mobile traffic reporting units, such as police or helicopters, etc. procured.
  • approaches have become known to make a traffic situation detection by relevant information from vehicles of a sampled vehicle fleet are transmitted to a central office.
  • FCD floating-car-data
  • traffic-relevant data of terminals in the vehicle are recorded automatically, by remote inquiry, or manually and transmitted together with a location information via a mobile telecommunications network directly to other mobile subscribers or a parent center.
  • the incoming data is processed further and passed on to selected terminals or third parties.
  • a system for carrying out the FCD method in which a communication unit, preferably according to the GSM standard, and a positioning unit, typically a GPS receiver, are structurally combined in a coherent, optionally separable module.
  • a communication unit preferably according to the GSM standard
  • a positioning unit typically a GPS receiver
  • the prior art also discloses solutions to the problem, which is that continuously transmitting the current speed of a plurality of vehicles places an extremely heavy burden on the transmission channels of the communication equipment used. So is out of the DE 197 30 794 a method is known in which the relevant position or speed data is not forwarded immediately to the center, if this data could not be relevant to a traffic situation. Rather, the transmission to the central office with the telematics device is only initiated if the data determined in the vehicle compared to stored traffic reports, which are sent at regular intervals by the center, contain new information.
  • FCD method can also be extended to the extent that measurement data are transmitted to the center, which not only affect the own vehicle, but also vehicles on other lanes.
  • the DE 103 22 303 describes a method in which data, such as mean speed or traffic density, is calculated separately for adjacent lanes. Thus, it is possible, at least in a local environment, to make a quantitative statement about the traffic.
  • FCD method in addition to a communication device, such as a mobile phone, and a position sensor, such as a GPS receiver, within the motor vehicle and special devices are needed. Since a large number of motor vehicles in the sampling fleet is needed to obtain an accurate picture of the traffic situation, it would be desirable to be able to dispense with the equipment with special terminals.
  • a recent idea, which is currently being tested, is the exploitation of the position determination by GSM phones. Here it is assumed that every mobile phone that is currently being used can be located very precisely - sometimes up to ten meters away. By determining the exact position of the mobile phone and continuous comparison of the position over time can be very accurately determine the distance traveled and speed of the motor vehicle. If such a method is applied to a sufficiently high number of motor vehicles, traffic density and traffic situation can be determined very accurately.
  • Disadvantage of such a method is that only the position of mobile phones can be accurately measured, which is currently being phoned. This significantly reduces the number of eligible vehicles that transmit traffic data to the center.
  • the object of the invention is to provide a method for collecting data on the traffic situation in a road network, in which not only information from Mobile phones that are currently on the phone, but can be used by all switched mobile phones.
  • the center By providing the center with information about the mobile radio cell or mobile radio cell group with which the radio communication unit is in contact, it is advantageously possible to work according to the principle of the FCD without the need for an FCD-specific terminal in the vehicle, and to gather information from all powered-on mobile phones when capturing FCD data, not just those currently on the phone.
  • the information used in the method according to the invention via the mobile radio cell or mobile radio cell group are those which, during operation - but not during a telephone call - in the continuous communication of the mobile phone with the mobile station, z.
  • a base transceiver station (BTS) are generated.
  • the center is supplied with the cell identifier of the respective mobile radio cell of the vehicle.
  • the center is supplied with additional information about the position of the radio communication unit in the mobile radio cell, which results from delay compensation or the like.
  • the knowledge of the respective mobile radio cell or mobile radio cell group in which the respective vehicle is currently located is sufficient to draw conclusions about the position of the respective vehicle when the information supplied to the center is compared with a digital road map.
  • FIG. 1 shows a road map and a cellular telephone network such as GSM, in which switched-on mobile phones are constantly logged in the system.
  • An activated mobile telephone 16 is carried along during a traffic journey in a motor vehicle 14. Initially, the vehicle 14 is in a position 18a on a traffic route 12a that is located in a mobile radio cell 10a.
  • the mobile radio system is in principle not known at which exact position the mobile phone 16 is located. Only when a call goes to a mobile phone 16, the exact position of the mobile phone 16 is determined by paging in the cell network. If the mobile 16 is only turned on, only the cell group 10 in which the mobile 16 is located, and When changing from one cell group 10 to the next, the sectional area of the respective cell groups 10.
  • the cell-characterizing information is forwarded to a central, not shown, for further processing and for generating traffic status messages.
  • the motor vehicle is in position 18b.
  • a cell change has thus taken place in the mobile radio cell 10b, which, however, does not yet make it possible to determine on which of the three roads 12a, 12b or 12c the vehicle 14 is located.
  • the motor vehicle is in the position 18c and thus in the mobile radio cell 10c.
  • the last cell change makes it possible to exclude the traffic lanes 12 b and 12 c for the vehicle 14.
  • the average speed of the vehicle 14 in the cell 10b can be determined between the two cell changes. This can be associated with the known or estimated traffic flow on the traffic route 12a. At higher determined speeds, a higher class traffic route (highway, main road) can normally be assumed, and at lower speeds secondary roads.
