KB10444 - DK routing and one-way street situations.

DK routing functionality supports one-way street situations. Each vector representing a street/road segment between intersection nodes can be coded with a cost factor that can be dependent on the order nodes are traversed, i.e., direction dependent.

Take, for example, a link defined by nodes 99 and 100 located at the ends of the link. A route passing first though node 99 and then to 100 could be discouraged or forbidden by assigning a prohibitively higher cost, whereas a route traversing the same link in the opposite direction, so first though 100 and then to 99, could be allowed by assigning a neutral cost.

The cost factor must be recorded in the appropriate attribute field of the subject line vector (link).
