Navigation system with connection simplification mechanism and method of operation thereof

A navigation system comprising:

• a control unit for:
• generating a junction node having a junction decision point,
• identifying an internal segment within the junction node, the internal segment connected to the junction decision point,
• identifying an external segment outside of the junction node, the external segment connected to the internal segment at the junction decision point,
• generating a traffic path through the junction node based on eliminating the junction decision point for merging the internal segment and the external segment,
• updating the junction node based on eliminating the traffic path in violation of a turn restriction,
• generating a preferred path through the junction node updated, and
• a communication interface, coupled to the control unit, for communicating the preferred path for displaying on a device.

A non-transitory computer readable medium including instructions for execution, the instructions comprising:

• generating a junction node having a junction decision point;
• identifying an internal segment within the junction node, the internal segment connected to the junction decision point;
• identifying an external segment outside of the junction node, the external segment connected to the internal segment at the junction decision point;
• generating a traffic path through the junction node based on eliminating the junction decision point for merging the internal segment and the external segment;
• updating the junction node based on eliminating the traffic path in violation of a turn restriction;
• and
• generating a preferred path through the junction node updated for displaying on a device.
