Method and apparatus for generating a steering instruction through the right or left turn path connection paths at the intersection

摘要

The present invention provides a method and apparatus for generating a manoeuvre 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, a method is provided for providing manoeuvre 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 manoeuvre indication, (c) collapsing the turn lane into the intersection when it is appropriate, (d) generating a manoeuvre indication for the collapsed intersection, and (e) outputting the manoeuvre indication to the user in time so that the driver may use the turn-lane connector if desired.
