Abstract: A navigation system for ascertaining qualified special destinations includes: a database, which stores transport route nodes and route sections connecting the route sections and properties thereof; a route computation device; and a memory device. Special destinations stored in the database are each linked to one or more connecting nodes, for example motorway exits. Each special destination has, for each connecting node linked thereto, at least one associated first total route, connecting the special destination and the connecting node to one another, and an associated total route length. At least in the event of the first total route having a use restriction, the special destination and the connecting node also have at least one associated second total route that, at least for one restriction parameter, has lesser use restrictions.

Abstract: The invention relates to a navigation system for ascertaining qualified special destinations, having a database, which stores transport route nodes and route sections connecting the latter and properties thereof, having a route computation device and also having a memory device, wherein special destinations stored in the database are each linked to one or more connecting nodes, particularly motorway exits, and wherein each special destination has, for each connecting node linked thereto, at least one associated first total route, connecting the special destination and the connecting node to one another, and an associated total route length and wherein, at least in the event of the first total route having a use restriction, the special destination and the connecting node also have at least one associated second total route that, at least for one restriction parameter, has lesser use restrictions.

Abstract: The invention relates to a method and a system which provides a routine for converting the formats of an IP address at a central location in the system. In this way, the conversion of formats is introduced as a standard for all IP-based applications programs. The system component is formed by a specially adapted operating system, an extended compiler or by a specific hardware microprocessor.
