Abstract
The present invention provides a method, system, and computer usable medium for indicating road direction for vehicle instruction for a one-way street. This may be done when a road database is provided and includes at least one start point and at least one end point to indicate a portion of the road. This may also be done by determining a center point between the start and end point. This may also be done by determining a compass bearing from the center point based on the position of the start point and end point. This may also be done by determining an angle of orientation indicator based on the compass bearing of the center point.
