Abstract

A method for selecting digital traffic messages in a radio receiver, with traffic messages concerning previously selected routes and corridors along the routes being selected and output.

Claims

1. A method for selecting at least one digital traffic message in a radio receiver, comprising the steps of:

(a) selecting a route;

(b) forming a planar corridor around the selected route;

(c) selecting at least one digital traffic message as a function of the planar corridor; and

(d) outputting the at least one selected digital traffic message.

2. The method according to claim 1, wherein step (b) includes the substep of:

adding plane elements around locations along the selected route, the sum of the plane elements encompassing the selected route to form the planar corridor.

3. The method according to claim 1, wherein the planar corridors are formed by rectangular plane elements encompassing locations along the selected route.

4. The method according to claim 3, wherein the rectangular plane elements include square plane elements.

5. The method according to claim 1, wherein the planar corridor is formed by individual plane elements, and further comprising the step of combining plane elements to form larger plane elements.

6. The method according to claim 1, wherein the planar corridor is formed by plane elements encompassing locations along the selected route, and further comprising the step of:

(f) combining the plane elements, wherein the locations along the selected route are positioned outside of a preceding element of the plane elements.

7. The method according to claim 1, wherein the selected route includes a plurality of routes, wherein a plurality of planar corridors are formed by combining plane elements associated with each of the plurality of routes, and further comprising the step of combining the plane elements associated with the plurality of routes to form a single planar corridor.

8. The method according to claim 1, wherein the planar corridors are formed by combining plane elements, one of the plane elements positioned around a start point of the selected route, another one of the plane elements positioned around a destination point of the selected route.

9. The method according to claim 1, wherein the planar corridors are formed by combining plane elements associated with locations along the selected route, and further comprising the step of combining adjacent elements of the plane elements to form a common larger plane element as a function of a predetermined offset.
