Definitions

  • the invention relates to a traffic control and information system with the features of the preamble according to claim 1.
  • the current and future traffic problems are due to the further expansion of the Road network not to be solved sustainably, but only by an intelligent one dynamic traffic management and information system, in which in addition to the Individual transport also includes local public transport.
  • Such a traffic control and information system is, for example, from the International publication WO 92/10824 A1 known.
  • a traffic control and information system in which means of transmitters in beacons on the roadside data such as road maps and Traffic information to which passing vehicles are sent.
  • the Vehicles have a corresponding receiver with which the data can be received.
  • the data is stored in the vehicle and processed. In this way it is possible, for example, to form the vehicle guide the previously entered destination.
  • graphic or Audiovisual information generated generated that corresponds to the driver of the vehicle instruct. In this way, the desired destination, for example, on the fastest (time) or shortest (route length) can be reached.
  • This system is one Control unit, a navigation unit, a data memory, a Radio receiver, a transmitter and receiver for beacon transmitters and one Information output unit built.
  • the navigation unit is operated by a GPS unit and other sensors, e.g. Wheel sensors, formed.
  • the data store is formed by a CD-ROM device and contains digitized road maps.
  • the Radio receiver has a facility for evaluating traffic reports on. Using the navigation unit and digitized road maps, the respective whereabouts can be determined. Starting from this location can a desired destination by means of the information output unit Output driving information that was determined by the control unit reached become.
  • the traffic announcements provided by the radio receiver can do this be taken into account, for example in order not to get stuck in a traffic jam.
  • Moreover can use the data from the beacon transmitters to create an individual and interactive targeting.
  • beacon transmitters already existing radio telephone system for the transmission of traffic control and Information data is used.
  • this system has the disadvantage that the transferable Data rate is relatively low, so that the transfer of data takes a longer time Period can take, causing traffic routing information below May be made available too late.
  • the object of the present invention is therefore a traffic control and Information system to specify that an individual and with little effort Interactive information and traffic management enabled.
  • the advantage of the invention is the fact that all for traffic management and Information required data are already stored in encrypted form. This makes it possible that the traffic management or information with only very short response times can be made. In addition, the Back channel used only to a small extent for the interactive information and Traffic management occupied.
  • FIG. 1 is a block diagram of a subscriber facility of the traffic control and information system according to the invention shown. It includes a control device 10, e.g. B. a microcomputer, a navigation system Determination of the current position, consisting of a GPS receiver 11 with antenna 12, a CD-ROM storage system 13, which, for example contains digitized road maps, and possibly other sensors, such as. B. wheel sensors. Furthermore, a radio receiver 16 with antenna 17, the Can evaluate traffic information, as well as a storage device 18, in which is the traffic information originating from the radio receiver 16 saved, available. There is also a user interface 19 available, the means for entering the desired information and means for Output of the information obtained from the subscriber device.
  • a control device 10 e.g. B. a microcomputer
  • a navigation system Determination of the current position consisting of a GPS receiver 11 with antenna 12
  • a CD-ROM storage system 13 which, for example contains digitized road maps, and possibly other sensors, such as. B. wheel sensors.
  • the means for input can be, for example, from a keyboard or from a Speech recognition system are formed, the means of outputting the information can both optical and acoustic means, such as a display and a speech synthesizer.
  • a return channel is provided via which the subscriber facility communicates individually with a central office can. The return channel can, for example, by a radio telephone after the GSM standard 14 with antenna 15 are formed.
  • FIG. 2 shows a block diagram of the center of the traffic control and information system according to the invention. It consists of a control device 20, a database 21 as well as an input device 22 and a memory 23 for current information. The center also has a connection 24 to a radio transmitter and a connection 25 to the return channel for the subscriber equipment.
  • the database 21 can, for example, be from a CD-ROM storage system are formed and may contain other information such as information about hotels, parking lots, etc. in addition to digitized street maps.
  • the input device 22 and the memory 23 current information that is subject to major changes, such as information about events or traffic obstructions, can be recorded and stored.
  • Control device 20 processes and the resulting data are used for Broadcast via connection 24 forwarded to the radio station.
  • the data from the control device 20 in encrypted or unencrypted form.
  • Be in unencrypted form for example, generates data that, for example, information about hazards included, e.g. B. "Wrong-way driver on the A6 motorway ".
  • encrypted form generated data can be special information, for example information about hotels or restaurants.
  • For the encrypted data will be accordingly the encryption key carried out by the control device 20 generated with which the encryption can be removed. It can be provided that different packets of information are formed, whose data is encrypted differently, one of the number of Packets corresponding number of keys is generated.
  • the data from the central station broadcast by the radio station are transmitted by the Received radio receiver 16 of the subscriber device and in the Storage device 18 stored. Are by means of the user interface 19th certain information is queried, the necessary data from the Control device 10 from the CD-ROM storage system 13 and the Memory device 18 accessed and the corresponding information on the User interface 19 output. Are the data or parts of the data in the Encrypted storage device 18, the control device 10 calls Subscriber facility the one or more necessary to decrypt the data Keys from the central office via the radio telephone 14, 15. In the head office goes Corresponding query of the subscriber facility via the radio telephone connection 25 and the control device 20 of the central unit provides the requested one or more Keys available over the radio link.
  • the querier Participants in the central office will be charged fees.
  • the fees can, however also be charged to the person who provides the information; for example, it can be interesting for hotel operators if Participants who have information about Get accommodations, their address is given, or if those participants from the traffic control system to their hotels.
  • the transmission of the data in encrypted and unencrypted form a broadcaster is mainly advantageous for collective data, i. H.
  • collective data i. H.
  • Special dates can also be made available via the radio telephone become.
  • the broadcasters broadcast collective data and the data transmitted by radio telephone are coordinated.
  • Radio transmitters according to the are particularly suitable for the transmission of the data DAB standard and corresponding radio receivers in the Participant facilities.
  • the radio station can also be a special one Data transmitter that is not from a broadcaster, but from, for example is maintained by a private operator. Then via this data sender for example, only data required for the traffic control and information system broadcast.
