Definitions
- the invention relates to a method for the selection and filtering of traffic information, preferably for use in a mobile radio-based traffic information service.
- the basis is a mobile radio-based one
- the object of the invention is to propose a method for the selection and filtering of traffic information, by means of which information which is individually prepared and only relevant for the user is transmitted.
- An essential feature of the invention is that the user is given a choice between a plurality of traffic information modes, so that he can call up the traffic information that is most interesting or directly relevant to him.
- the traffic data can be filtered in such a way that out of a multitude of traffic information only those reach the user that are important to them.
- the traffic information service provides the user with three modes, which he can select as required: 1. Local traffic information (Lok)
- the user can activate a voice output in the query menu for traffic information or in the basic configuration menu. If this function is active, the relevant traffic information is also recorded in voice form on a voice mailbox and can thus be called up by the user.
- the voice mailbox automatically informs the user of the presence of new messages. The user then initiates the query of the mailbox.
- the data records contain information on the type, priority and direction vector of the fault, as well as geographical information on the fault.
- a target address TARGET POSITION is also required, which is either determined by the service center by determining in which radio cell of the mobile radio system the user is, or is determined by a GPS location system that is integrated in the terminal or vehicle and transmits the exact position data to the service center.
- the size of the reference area to be assigned i.e. the number of sub-areas (grid squares) about which traffic information is to be provided depends on the density of the (long-distance) road segments that exist in the area of the START-POSITION.
- the selected information is transmitted in data form to the vehicle-side terminal.
- a grid (e.g. 10 km x 10 km) is shown on the digital map. Every single grid square is a
- the size of the reference area is calculated with PVD, whereby the reference areas are larger in rural areas than in urban areas.
- the traffic density parameter PVD can be assigned as follows:
- conversion parameters for direction vectors can be specified for the grid squares, in order to be able to take geographical features into account when filtering the information later (see below).
- the traffic information is stored as data records in the database of the traffic department. This record contains:
- the data records are each assigned to one or more (if large-scale disturbances) grid squares.
- the basis for the selection of information consists of all available actual information and forecast data for the next few hours. This information is assigned to the affected grid squares in a database. Basically, information of all detail zones (highways to urban area) can be processed, since filtering functions are defined and therefore there is no danger of "flooding with information”.
- Figure 1 Example of the menu structure of the terminal-side application of the traffic service
- Figure 2 Example of a possible hardware implementation of the method according to the invention
- FIG. 3B flowchart of a vehicle traffic service query
- Figure 4 Example of determining the reference range of information in the "local” and “regional”mode
- Figure 7 Example of filtering the information in the "vek” mode.
- Figure 1 shows an example of the menu structure of the terminal-side application u.
- the main menu offers the option "V-Info" to select the traffic service.
- the "V-Info" submenu opens and you can choose between three area modes, according to local, regional or targeted traffic information. If the targeted information is selected, the desired destination must be entered in the "Destination" selection menu. This can be done by specifying the destination coordinates, a corresponding telephone number or the postcode of the destination.
- the traffic information is output as text or, if desired, as voice information.
- FIG. 1 shows the application environment of the
- Traffic information service In a service center, in which the user-specific database is located and which is responsible for the billing of the services used (billing), a traffic editorial office is provided according to the invention, in which the traffic information from various sources accumulates, is processed and processed.
- the traffic data are linked to a digital map and assigned to individual geographical "grid squares" on this map.
- Via a user module "V-Info" the traffic data can be queried by the road user via the GS mobile radio network become.
- the query and the exchange of information is controlled by a communication server, which establishes the connection between the telecommunications system at the headquarters and the GSM system or the vehicle. If the user desires a voice output, the traffic information is spoken onto the voice mailbox using a voice generator, and can then be called up / listened to by the user via his terminal.
- FIGS. 3A and 3B show a flowchart of a vehicle service traffic query.
- the user is guided through the traffic information query via his end device with the aid of a menu guide.
- the flow chart is self-explanatory and gives detailed insights into the menu structure and its links as a supplement to the rough overview in Figure 1.
- Traffic info menus choose between three modes (see figures).
- the exact size of the environment or reference area should not be fixed. Instead, the relative terms “local” and “regional” are used.
- the exact size of the reference area to be queried is calculated in the control center. With this method, the determination of the reference range is made more comfortable and effective than a fixed km specification. It is thus possible to adapt the size of the reference area to the traffic density of the area of residence: in rural areas, for example, the area queried with “local” is larger than in conurbations.
- the STARTING POSITION is in one
- the TARGETING POSITION is southeast of the starting position.
- the information in the reference area is checked for redundancy.
- the system can rule out multiple answers based on the reference numbers assigned to each individual traffic information record.
- FIGS. 5 and 7 describe how the traffic information is further filtered, taking into account the direction vectors. This is to ensure that the user receives only the information that is relevant to him and, for example, no information that is intended for the opposite direction.
- filtering data a distinction is made between the local / regional modes and the targeted mode vek.
- centrifugal direction In the "local” and “regional” modes, no basic direction vector is specified and therefore it is only possible to filter according to the "centrifugal direction", ie primarily traffic information is taken into account, the direction vector of which is seen from the position of the vehicle point outwards. In the starting grid square, information with all direction vectors must therefore be taken into account. In the surrounding grid squares of the reference area, the centrifugal directions, based on the starting grid square, can be used to filter the information (see Fig. 5). This filtering is limited to a range of approx. 90 ° to the left and right of the centrifugal direction vectors, ie to a total of 180 °, so that tolerances due to geographic road patterns can be included.
- the known travel destination which corresponds to a specific target grid square, specifies a basic direction vector according to which it is possible to filter.
- the start grid square information with all direction vectors must be taken into account.
- the superordinate direction vector based on the target grid square, is used to filter the information (see Fig. 7)
- This filtering is limited to a range of approximately 90 ° to the left and right of the direction vector, that is to say a total of approximately 180 °, so that tolerances due to geographically determined road courses that deviate from the theoretical direction of travel can be included.
- the filtered information of the reference area is output as data records.
- each data record also contains the position of the respective fault in order to enable the position-dependent and direction-dependent display of the information in the vehicle's end device (automatic mode).
- the position can be a point or a geometric figure.
- the output message (TINFO_response) is generated from the data records and transferred to the communication server together with the subscriber identity (T-ID).
- TINFO_response If, after generation of the output message (TINFO_response), new important messages for the reference area arrive within a defined period, these should be passed on to the user.
