Definitions

  • the invention relates to a method for the creation of an end device User of a terminal device traffic information to be output and a terminal device.
  • Traffic reports usually contain the state of a segment Road network representing status information and identities Segment numbers representing affected segments, such as the expert is known for example from the RDS-TMC standard. State information can for example in the form of traffic jam information, speed information or travel times are transmitted. Segment numbers for segments of streets are usually in the traffic information center and in the terminal as possible largely identical tables available.
  • the broadcast is usually via a text information channel that is basically similar to teletext in television a radio station.
  • the messages are in the end device, as far as for the local position or direction of travel of importance, optically and / or acoustically or for used the optimization of a navigation.
  • the object of the present invention is the most efficient information possible Terminal user about the state of segments of a road network taking into account traffic reports sent from the terminal.
  • the object is solved by the subject matter of the independent claims.
  • the terminal is based on the (for example in RDS-TMC segment tables) consecutive numbering of at least some segments a road network from individual traffic reports related, outputable to a user of a terminal Created traffic information, the number of to be output is reduced Traffic information. Moreover, only a relatively small one Traffic information memory for traffic information to be output to the user required. Furthermore, a smaller display can be realized with optical output, because less traffic information has to be output.
  • Traffic information (traffic jam, slow moving traffic, traffic jams, free traffic) in Form of only one traffic report to the terminal, but what due to the digital maps of Road networks in the terminal and in the headquarters is difficult. It would also be too memory intensive, all combinations of segments for possible traffic jams in Tables in the terminal and in the headquarters to enable efficient Save transmission in a traffic announcement.
  • Traffic information received from a terminal can in particular be sent via Radio (especially RDS-TMC) can be received.
  • RDS-TMC Radio
  • Figure 1 shows a terminal 1 with a receiving device 2 for receiving (3) traffic reports sent from a central station to one or more terminals and a memory 4 for storing received traffic reports 5,6,7, a traffic information generation device (comprising a search device 9 and a traffic information text synthesis device 10) and one Output device 11 for outputting traffic information 12 to a user 13 of the terminal 1.
  • a receiving device 2 for receiving (3) traffic reports sent from a central station to one or more terminals and a memory 4 for storing received traffic reports 5,6,7, a traffic information generation device (comprising a search device 9 and a traffic information text synthesis device 10) and one Output device 11 for outputting traffic information 12 to a user 13 of the terminal 1.
  • the terminal 1 receives traffic reports (5, 6, 7) by radio from a central station.
  • This is usually done via RDS-TMC via a special channel Radio stations.
  • RDS-TMC via a special channel Radio stations.
  • a mobile radio channel in particular via a short message channel (under GSM or UMTS) as to a terminal 1 directed short message (SMS-MT) or directed to a variety of devices Mobile short message (SMS-CB).
  • SMS-MT terminal 1 directed short message
  • SMS-CB Mobile short message
  • With a transmission via mobile radio can also a designation of segments of a road network by also under RDS tables are used, as is an order code of Status information (specific indicators for traffic jam, slow-moving traffic, free Traffic etc.).
  • Segments of a road network can be geographical Sections of roads, lanes or lane groups.
  • a segment can, for example, all lane groups between two junctions Designate the motorway or country road with the same direction of travel.
  • Traffic reports received by the receiving device 2 are in one Memory 4 of the terminal 1 saved.
  • the examples listed here Traffic reports 5, 6.7 are: Traffic report 5: "4711, 2 km, traffic jam" what means that there are two km of traffic jam in segment with number 4711. The same applies to traffic reports 6,7 relating to segments 4712 and 4713.
  • the traffic information generation device searches with a search device 9 in Memory 4 after traffic reports with numerical or alphanumeric consecutive segment number, the traffic reports 5,6,7 are found here regarding segment numbers 4711, 4712 and 4713, while others (not traffic messages shown) are not numbered consecutively in the memory 4, as it would be for example 4710 and 4714, which are not contained in memory 4 here are.
  • These traffic reports 5, 6, 7 found by the search device 9 with Successive segment numbers are stored in the comparison device 14 now compared in terms of whether the status information contained in them (here "traffic jam" for each of the traffic reports 5,6,7) are the same.
  • Under “equal” is understood here as “identical”, but it would also be possible to comply with Define threshold values as “equal”. Thresholds would be special useful if the status information is speed information or Travel times included.
  • the comparison device 14 determines that the search device 9 in the Memory 4 found traffic reports 5,6,7 the same status information (here "traffic jam") is from the traffic information text synthesis device 10 a common one to be issued to the terminal user (11) Traffic information text 12 created.
  • the Traffic information text synthesis device 10 to a further memory 15 in the Terminal 1 to which to each (via RDS or cellular) as a segment number transmitted segment (4711, 4712, 4713 for traffic reports 5,6,7) one here the geographical extent on a map (a normal paper map) represents representative text in the terminal user 13 understandable form. So the memory 15 to the junction 4711 contains the text information that the End of segment 4711 is the connection point A and at the other end Junction B.
  • the memory 15 for segment 4712 stores that at one end the connection point B and at the other the connection point C is present.
  • segment 4713 it is stored that it is from the connection point C to extends to junction D.
  • the ends of segments can be used instead of Junction points, for example, through other references, such as references to cities, Rest areas, etc.
  • the traffic jam extends from Segments 4711 to segment 4713, so that the first junction of the Segment 4711 (A) and the last connection point of the last segment 4713 (D) in the traffic information text message 12 together with other text modules ("between connection point", "and") can be integrated.
  • a memory 15 for further acoustic messages for numerical via RDS, TMC or GSM or UMTS transmitted traffic reports are available.
  • the traffic information text synthesis device is therefore created the traffic information 12: "between junction A and junction D 6 km Traffic jam "Instead of 'A" and "D" can in reality also be a city name or that A branch road, etc.
  • the traffic information 12 is sent to the terminal user by an output device 11 13 is represented optically or acoustically, in particular in the case of an optical representation According to the invention, a smaller display is required for a clear presentation. With an optical as well as an acoustic output device, due to the reduced number of traffic information to be output a smaller memory required for traffic information to be output.
