Abstract
A device for coding and decoding locations in a transportation network, providing that information concerning these locations are transmitted from one transmitter to one receiver. In the device, the code is composed of a declaration portion and a coordinate portion corresponding to each coded location. The coordinate portion includes a plurality of coordinate pairs, one coordinate pair representing the coordinates of the coded location stored on the transmitter side and at least one other coordinate pair representing an auxiliary point. The declaration portion includes at least the number of coordinate pairs contained in the coordinate portion, the position of the coordinate pair of the coded location in the coordinate portion, and an indication of the type of coded location. For decoding purposes, locations falling within the tolerance range of the received coordinate pairs are determined in a location database that contains the coordinates, the position at any time on the traffic route and additional location information. Of the specified locations, the ones situated on a common traffic route are selected; and of these selected locations, the one that falls within the tolerance range of the specified coordinate pair can be defined as the decoded location.
