ROUTE GUIDANCE SYSTEM AND PROGRAM Russian patent published in 2010 - IPC G01C21/36 

FIELD: physics.

SUBSTANCE: route guidance system includes: a unit for detecting current location; processing apparatus for compiling a list of strips which a list of strips (Ls1) taking into account connection between strips for groups of strips (from Lk1 to Lk3) in road junctions in the road list displaying area; processing apparatus for determining the visualisation region which determines whether the number of strips in the list of strips (Ls1) is greater than the number of strips in the display unit; and apparatus for processing and controlling the display region, which selects predetermined strips in a list of strips (Ls1) and displays selected strips only.
