Definitions
- the invention relates to a method for selecting a route of a vehicle with a terminal in a traffic network, which is transmitted from a central station, and a terminal and a central station for carrying out the method.
- a route through the traffic network from a desired starting point to a desired destination in a traffic center can be determined on the basis of distances, current traffic information, such as traffic jams, etc. and transmitted to the terminal.
- a determination of a route between a desired starting point and an end point in the traffic network is also possible in the terminal.
- Traffic information about a location that is far from the current location is of secondary importance, in particular for the decision about updating a route. If a complete map of the traffic network being traveled through is present in the terminal, an assignment of traffic information received in the terminal and transmitted by the traffic control center to specific streets or cities is ect. possible. In the absence of a complete digital map of the traffic network traversed, it is not possible to identify roads affected by traffic information in the terminal for the relevance check for the current route.
- the object of the present invention is to enable the simplest and most efficient travel check of traffic information, taking into account a route through which the vehicle travels with a terminal Transport network.
- the object is achieved in each case by the subject matter of the independent claims.
- the method according to the invention for selecting a route of a vehicle with a terminal in a traffic network and relating to it, traffic information sent out from a control center (such as traffic jam information, traffic density, travel times) enables simple, efficient even in the absence of a digital map of the traffic network or incompleteness of the digital map and error-prone allocation of received traffic information including a relevance check with regard to the route traveled.
- traffic information sent out from a control center such as traffic jam information, traffic density, travel times
- a zone in particular a corridor, between two waypoints of a route defined by waypoints enables a good selection of traffic information along the route.
- Selected traffic information can in particular be communicated optically and / or acoustically to the user of the terminal, with the user being spared from insignificant traffic information.
- traffic information selected as being significant for the route can be used to assess the need for a route recalculation, which is considerably cheaper in terms of telecommunication costs than ongoing interactive communication between the terminal and the traffic center on the question of route recalculation.
- a route recalculation can be done in one
- Traffic control center takes place, which has the advantage that current traffic information is optimally allocated and included locally with great computational effort and that only a very detailed map of the traffic network is required in the traffic control center.
- a route recalculation can also be carried out in the terminal, which enables greater self-sufficiency.
- a zone is expediently defined between two successive waypoints of the entire route.
- zones in particular corridors
- the definition of zones, in particular corridors, is expediently carried out in the terminal on the basis of the waypoints of the proposed route transmitted with their geographical positions (in particular geographical longitude and latitude with a predetermined rounding).
- the zone between two waypoints is expediently defined as a corridor between two straight lines parallel to a connecting line (in particular a straight line) between two waypoints each with a predetermined or predeterminable distance to the connecting line.
- a zone is particularly easy to calculate in the terminal and enables a simple check to be made as to whether transmitted
- Traffic information is in this zone. This results in an approximately rectangular partial corridor between two waypoints.
- the distance between the two parallels to the connecting line between two waypoints is kept unchanged. This enables simple calculation. Furthermore, it is possible to increase the distance with increasing distance from the current location, in order to take into account that traffic information to locations further away from the route can become significant further away, until the vehicle has moved there because the travel time there Traffic jams etc. can propagate up to the route.
- Traffic information such as traffic jam reports, average speeds, travel times, accidents, etc.
- Traffic information is transmitted from the traffic control center to the end device expediently with a description of the road, streets, road sections, cities, etc. affected by the traffic information.
- a location for traffic information is advantageous , which can take place in particular as the geographical longitude and latitude of the location or locations concerned by the traffic information.
- the request from the terminal to the traffic control center for a new route calculation is expediently made by radio, in particular mobile radio.
- Route information defining the waypoints of a route is expediently transmitted from the control center to the terminal by a route calculation in the control center
- Traffic information on the traffic situation can be transmitted by radio; in particular, they can also be transmitted by mobile radio, in particular as a mobile radio short message (GSM SMS); Traffic information can in particular also be broadcast locally, for example in locally defined GSM SMS pages.
- GSM SMS mobile radio short message
- a user of a terminal in a vehicle gives the starting point
- the terminal transmits the starting point and end point to a traffic control center, not shown.
- the calculated route is transmitted from the traffic control center to the vehicle by route information which define waypoints along the route. Waypoints can be defined in particular where a street along the route changes its name due to a junction, street renaming etc., which is particularly advantageous for a terminal without a digital map of the transport network.
- a route is therefore a chain of waypoints between the starting point and the destination of the desired journey through the transport network.
- route information defining the waypoints of the route in particular the street name of the road to be traveled between two waypoints can be transmitted from the control center to the terminal.
- geographical information on a waypoint in each case in particular its geographical longitude and latitude rounded to a predetermined length, can be transmitted.
- a driver receives traffic information via radio and / or mobile radio from the traffic control center, in particular about traffic jams etc. These can be displayed to the driver and / or used as the basis for a decision on recalculating a route due to traffic jams etc. .
- Figure 1 shows two waypoints W and W, which define a section of the route of the vehicle through the traffic network. A straight line G is drawn between these two waypoints W and W. Traffic information relating to a point P, which has a distance from the straight line G that is above a predefined or predefinable limit value, is selected as not relevant; Traffic information on a location P, which is at a distance from the straight line G below a predetermined limit value, is selected as relevant, whereupon it is displayed to the user, for example, or can form the basis for a decision about a route recalculation.
- FIG. 1 shows traffic information (to a location P) which is at a distance from the straight line G above a limit value x 2 meters, which is why the traffic information to the point P is selected as not relevant.
- the traffic information relates to a location P which has a distance from the straight line G below the limit value, that is to say a distance below x / 2 meters, which is why the traffic information is selected as relevant.
- the distance of the point P from the straight line G can be determined in particular on the basis of geographical coordinates of W,.
- the zone in which traffic information is relevant is here, for example, a rectangle, which is defined by two parallel Z1 and Z2 to the line G between the two waypoints W, W (and by orthogonal to G through the waypoints W, W). Since there are further waypoints to the proposed route to the left and right of W in FIGS. 1, 2, there is overall a corridor for the route along the proposed route as a zone within which traffic information is relevant.
- the invention can be implemented in a terminal and / or a control center, in particular as a program.
- program parts for the selection of traffic information relating to a zone between two waypoints are to be implemented in the terminal.
- An embodiment as an electronic circuit is also possible.
