Definitions

  • the invention relates to a device for the transmission of Route recommendations for at least one network of public Transportation to recipients and a recipient for Route recommendations.
  • WO 96/00960 is an electronic Timetable information system, in which Information beacons continuously, i.e. without being asked Passengers send data received from handheld terminals become.
  • the data concern public transport networks and Timetables can be saved and saved in the hand terminal Timetable information is processed, which is then sent to the user are displayed.
  • Such a system requires special for developed and developed this public transport manufactured hand-held terminals.
  • the object of the present invention is to provide such To transfer route recommendations if necessary, that the known inexpensive in large quantities manufactured receivers also for the reception of Route recommendations from public transport networks can be used, including a link to the Road network can take place.
  • a coding by means of at least one imaging at least parts of the transport network Location database is that for Transfer of route recommendations that are also in at least one location database depicting a road network (Road network location database) relate to stored locations, Records of those places that have at least one neighboring location in the at least one road network location databases have at least one reference to at least one such neighboring location by means of a Cross-reference included.
  • a first embodiment of the device according to the invention is that for the transmission of digitally encoded Traffic reports (TMC) provided data protocols be used.
  • TMC Traffic reports
  • An RDS-ODA protocol will be set up for transmission used.
  • the device according to the invention has the advantage that the Route recommendations of a large number available Receiving devices can be received and decoded.
  • Receiving devices there are currently essentially car radios for receiving digitally coded traffic reports - both in Relation to RDS (radio data system) and as well DAB (Digital Audio Broadcasting).
  • RDS radio data system
  • DAB Digital Audio Broadcasting
  • the invention can also be used with other mobile radio media such as GSM, SWIFT, UMTS.
  • the receiver is installed in a vehicle that has a location system (e.g. GPS) or a Navigation system can also select the Route recommendations according to the selection of the Traffic announcements are made that the recipient receives only those route recommendations that are likely to be of importance to the user.
  • a location system e.g. GPS
  • a Navigation system can also select the Route recommendations according to the selection of the Traffic announcements are made that the recipient receives only those route recommendations that are likely to be of importance to the user.
  • the device according to the invention also has the advantage that for route recommendations, for which also data from Road networks are needed, for example the Traffic flow on roads and highways are taken into account is that for the TMC system or similar systems automatically recorded data can be used.
  • the route recommendations are longer than a traffic report transmitted by the TMC system, e.g. traffic jam, 5 km in length, A7 motorway, junction Hildesheim. That is why according to a training course provided that the route recommendations as Multi-group messages are transmitted.
  • An advantageous recipient for route recommendations at least one public transport consists of that for decoding in the receiver at least one at least Location database depicting parts of the transport network (Traffic network location database) is provided and that for Decoding of route recommendations, which are also in at least one location database depicting a road network (Road network location database) relate to stored locations, Records of those places that have at least one neighboring location in the at least one road network location databases have at least one reference to at least one such neighboring location by means of a Cross-reference included.
  • Such location databases are preferably on one removable disk, so that the user of a recipient is the one that most interests him Traffic networks available, without location databases for everyone To acquire traffic networks, for example of a country have to.
  • the receiver according to the invention can also be used in this way be trained that the location database on a Air interface is upgradeable.
  • this receiver are for Management and decoding of route recommendations Digital management and decoding facilities coded traffic reports (TMC) provided.
  • TMC coded traffic reports
  • Fig. 2 shows an example of a route network, the partly the area of a big city 1 and partly that Surrounding area 2 runs through.
  • a tram line 3 leads from one first end point 6 via stops 7, 8, 9, 10 to one second end point 11.
  • Stop 8 is a transfer point to a bus line with endpoints 12, 15 and others Stops 13, 14.
  • the stop 10 serves as Transfer point to a P + R car park at the junction a highway 5, from which further junctions 16, 17, 18th are shown.
  • the route network shown can in the same way as that Road networks are encoded in the TMC system, that is Location databases as described in the ALERT C standard are, the individual places lead in connection with on a line, to any location, for example to the Stop 7, a predecessor 6 and a successor 8 as Cross-reference are provided. Since the transfer point 8 is also a Location on bus line 4, there is an additional one Referencing, such as that used in patent applications 196 06 010 is shown.
  • lines 3, 4 of the public Transport network in a specially designed for this Place database shown or in an existing Location database integrated while the Autobahn 5 in one conventional location database within the TMC system corresponding cross-references can be found at the place 10 on the other route (highway or Tram line).
  • This can be a message that for example, "use the freeway to Junction 10, then change to tram line 3 towards the final stop 6 to the change point 8 and then use bus line 4 in the direction of end point 12 to Stop 13 "with the usual protocols in the TMC system or protocols defined within the scope of ODA applications encoded and transmitted to the recipient, who then uses its location database (s) a coding and implementation can make in text or speech.
  • the one to be transferred Amount of information also deviate from this table. Also, because of the very compact coding, you do not need all message elements to be transferred. So can for example message elements, such as means of transport, Line name, line end point for decoding from the Location database can be taken.
  • the bit at position Y15 identifies the first group of a message.
  • Each group has a length of 37 bits, which in the Example with X4 to X0, Y15 to 0 and Z15 to Z0 are.

  • FIG. 3 shows a similar route recommendation as FIG. 1, however, the coding is done in a RDS-TMC compatible Form, with a maximum of only four transfer points U1 to U4 can be encoded. Even the transfer of Additional information is limited to one statement in the present example on the train sequence ZF.
