Definitions

  • the present invention relates to a method for route planning.
  • the invention relates to a method for the mobile information of people about traffic obstacles, in particular traffic jams, and the dynamic determination of detours to avoid these traffic jams.
  • EP 1 206766 A1 proposes such a method according to which a map of the surroundings is displayed on a WAP-capable mobile radio terminal, on which traffic disturbances can be read.
  • the disadvantage of this method is that in the event of a malfunction on the planned route, the user only receives the information that delays can be expected on the planned route. This does not provide any information on how to avoid this traffic jam.
  • the object of the invention is to provide a method for informing the user of traffic disruptions and detour options relating to the use of commercially available mobile radio terminals for information transmission and location determination.
  • the invention solves the problem with the features of claim 1.
  • Advantageous refinements are specified in the subclaims.
  • the essence of the invention is that an end user can display the current traffic information situation on his mobile terminal by means of Internet access, which is for a street determined by the user, in particular a numbered street such as a motorway or federal highway, a metropolitan area selected by the user or the current one Location in which a location is determined for the mobile radio terminal by means of the localization unit.
  • the traffic information situation is displayed on the mobile radio terminal by determining the current traffic situation from the traffic information database. It can be displayed in any way, e.g.
  • the location-specific query carries out a spatial query in the vicinity of the location on the traffic information database.
  • a suitable surface design enables the end user to display more precise information on individual traffic disruption events.
  • the complete message text including additional information can be displayed, but also a further detailed map that shows the complete traffic disruption situation. Only a pure selection of a traffic disruption situation is also possible for the further course of the method, without additional information or a separate map being displayed.
  • a request can now be sent to the head office automatically or by user input to calculate a route that begins before the selected traffic disruption and ends after it, i.e. a detour is calculated.
  • the result of this route calculation can be presented to the user both as a waypoint list and as one or more maps.
  • the mobile radio terminal is advantageously suitable for displaying internet pages (for example via WAP) and optionally graphics and can display the georeferenced traffic information transmitted from the traffic computer to the mobile radio terminal on a geographical map.
  • end devices for example future 3G solutions which enable access to the Internet, can also be used in the method according to the invention.
  • other devices are also suitable, which have have a wireless radio connection or can be connected to a corresponding mobile terminal, such as PDAs, mobile computers etc.
  • the selection of traffic information can thus be made via a suitable surface design of a geographical map displayed on the mobile radio terminal or also within a text that e.g. is shown as a list.
  • the location of the mobile radio terminal is determined by means of a position determining device and transmitted to the traffic computer.
  • This location is shown centrally on the geographic map shown.
  • the location can be determined by means of a position determining device, e.g. GPS, or be carried out by means of a position determination on the basis of the mobile radio network.
  • the position determination device does not necessarily have to be present in the mobile radio terminal itself, but can also be present in the vehicle used and can be transmitted to the latter by suitable short-range communication between the vehicle and the mobile radio terminal.
  • the determined location of the mobile radio terminal in the traffic computer is advantageously used in such a way that only traffic information in a specific and size-definable radius around the determined location of the mobile radio terminal is determined.
  • the user can also request a selection of the traffic information to be transmitted on the basis of an entered street name or an entered street number or a selected region.
  • the traffic information can be selected individually on the mobile radio terminal in accordance with the road sections to which it applies.
  • the expected transit time for the calculated alternative route is determined by the traffic computer and compared with the anticipated required transit time for the respective selected traffic segment, and the times and the difference value of the determined times are output to the mobile radio terminal.
  • the alternative route can be displayed graphically on the mobile terminal on one or more geographic maps or as text, for example as a waypoint list.
  • the alternative route can also be displayed on the mobile terminal as a waypoint list supplemented with waypoint-specific geographic maps.
  • the method can therefore also be used when it is not possible to display maps graphically.
  • the traffic disruptions in the area are only communicated in text form and the route calculation can then be started by selecting a traffic disruption report, the result of which is e.g. is sent back to the user's mobile terminal as a waypoint list.
  • the method can be designed in such a way that the user must first register before using the service.
  • a usage-based billing can be carried out via this registration, the payment of which e.g. done on the bill of the mobile operator. This means that the user can be authenticated using a user ID.
  • the route calculation software can determine as a result that bypassing the fault message does not bring any time advantage.
  • This variant is particularly relevant if the delay time for the passage through the disturbance is also specified in the traffic information database for a traffic disturbance.
  • this behavior can also be switched off by the user.
  • a road section is selected as the starting point of the route calculation, which is before the last possible branch of the traffic disruption. In the case of a freeway, this is necessarily before a freeway exit or a cross / triangle. The same applies to the destination, which must be behind the first possible access after the traffic disruption situation.
  • 1 shows a geographic map 3 according to the invention with the identification of a road section that contains traffic information 1, and an alternative route guidance 2.
  • FIG. 2 shows how a mobile radio terminal 7 directs a routing request 12 to the control center 4.
  • the routing request 12 is received in a portal server 8, which is preferably designed as a WAP portal server.
  • the current traffic status data are determined from the traffic information database 6 in accordance with the road section identified with the routing request 12.
  • Corresponding excerpts from a digital road map 5 contained in the traffic computer 11 are transmitted to a navigation server 9 and to a map rendering server 10, which create an alternative route guidance 2 for the relevant traffic information and present it on a map and which in turn forward the information they have created to the portal server 8 , of which, as a result 13, the traffic state data is transmitted as traffic information 1 to the mobile radio terminal 7 and is displayed on the latter when the user of the mobile radio terminal 7 authenticates himself by entering his user ID 14.

Abstract

L'invention concerne un procédé de planification d'itinéraire, consistant à transmettre des données relatives à l'état du trafic en des points ou sur des tronçons déterminés d'un réseau routier, ces données contenant des informations sur l'état du trafic dans au moins un sens de circulation, à une base de données d'informations routières d'un ordinateur de gestion du trafic côté central, cet ordinateur comportant une carte routière numérique. Le procédé selon l'invention consiste ensuite à déterminer sur demande pour un téléphone mobile, relativement à une zone sélectionnée, les données actuelles concernant l'état du trafic à partir de la base de données d'informations routières de l'ordinateur de gestion du trafic.
