ABSTRACT:
The present invention provides a method and apparatus for generating a maneuver indication for an intersection having a turn-lane connector which is consistent with what a driver sees and expects. According to one aspect of the invention, it provides a method for providing maneuver indications to a driver for an intersection having a turn-lane connector which includes the steps of (a) determining when the intersection includes a turn-lane connector, (b) determining whether it is appropriate to collapse the turn lane into the main portion of the intersection for the purposes of generating a maneuver indication, (c) collapsing the turn lane into the intersection when it is appropriate, (d) generating a maneuver indication for the collapsed intersection, and (e) outputting the maneuver indication to the user in time so that the driver may use the turn-lane connector if desired.
