Abstract
In areas where composite intersection traffic regulation exits, nodes and links for use in the conventional network are separated into a plurality of nodes and links, respectively. For example, one node is separated into N1a to N1c, and one link is separated into L1a to L1c. Then, the whole road network is represented by separating the network into a road network (L1a, L2a, L3a, L4a, L5a, N1a, N2a) in view of entering links (L1a, L3a) which the composite intersection traffic regulation does not affect, and road networks .alpha. (L1b, L2b, L3b, L4b, N1b, N2b) and .beta. (L1c, L2c, L3c, L5c, N1c, N2c) in view of entering links (L4b, L5c) which the composite intersection traffic regulation affects, and one-way traffic regulations are set on suitable links to allow for a representation of the composite intersection transfer regulation. Use of such map data enables selections which are compliant with the composite intersection traffic regulation without requiring a specific processing at the time of the search processing.
