Navigation system with traffic flow mechanism and method of operation thereof

1. A method of operation of a navigation system comprising:

determining a buffer distance meeting or exceeding a size threshold between obstacle locations;

determining a merge timing based on a current location relative to the buffer distance;

determining a lane placement based on a travel time meeting or exceeding a time threshold wherein the travel time represents a time required to travel from a start location to a target destination and the lane placement determined based on comparing the travel time to multiple instances of the time threshold for selecting a lane wherein each lane placement has the time threshold set differently from one another; and

executing a lane merge operation with a control unit based on the merge timing, the lane placement, or a combination thereof for guiding a user's vehicle to merge onto the lane different from currently traveled.

2. The method as claimed in claim 1 wherein determining the lane placement includes determining the lane placement based on a travel distance meeting or exceeding a distance threshold.

3. The method as claimed in claim 1 further comprising switching an operation mode based on the current location relative to a road segment.

4. The method as claimed in claim 1 further comprising adjusting a lane speed based on a travel context for controlling a travel speed, an obstacle speed, or a combination thereof.

5. The method as claimed in claim 1 wherein determining the buffer distance includes determining the buffer distance based on a physical distance between the obstacle locations greater than a user's vehicle size.

6. The method as claimed in claim 1 wherein determining the buffer distance includes determining multiple instances of the buffer distance different from one another based on a travel context.

7. The method as claimed in claim 1 further comprising generating the buffer distance based on adjusting an obstacle speed to create a physical space meeting or exceeding a size threshold for allowing the user's vehicle to merge into the lane.

8. The method as claimed in claim 1 further comprising adjusting the merge timing based on a travel context for adjusting the merge timing to different instances of the buffer distance within the travel context.

9. The method as claimed in claim 1 further comprising denying a lane exit operation based on an exit distance below a distance threshold.

10. The method as claimed in claim 1 further comprising guiding to an alternative exit location based on an exit distance below a distance threshold.

11. A navigation system comprising:

a control unit for:

determining a buffer distance meeting or exceeding a size threshold between obstacle locations;

determining a merge timing based on a current location relative to the buffer distance;

determining a lane placement based on a travel time meeting or exceeding a time threshold wherein the travel time represents a time required to travel from a start location to a target destination and the lane placement determined based on comparing the travel time to multiple instances of the time threshold for selecting a lane wherein each lane placement has the time threshold set differently from one another;

executing a lane merge operation based on the merge timing, the lane placement, or a combination thereof; and

a communication unit, coupled to the control unit, for transmitting the lane merge operation for guiding a user's vehicle to merge onto the lane different from currently traveled.

12. The system as claimed in claim 11 wherein the control unit is for determining the lane placement based on a travel distance meeting or exceeding a distance threshold.

13. The system as claimed in claim 11 wherein the control unit is for switching an operation mode based on the current location relative to a road segment.

14. The system as claimed in claim 11 wherein the control unit is for adjusting a lane speed based on a travel context for controlling a travel speed, an obstacle speed, or a combination thereof.

15. The system as claimed in claim 11 wherein the control unit is for determining the buffer distance based on a physical distance between the obstacle locations greater than a user's vehicle size.

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

determining a buffer distance meeting or exceeding a size threshold between obstacle locations;

determining a merge timing based on a current location relative to the buffer distance;

determining a lane placement based on a travel time meeting or exceeding a time threshold wherein the travel time represents a time required to travel from a start location to a target destination and the placement determined based on comparing the travel time to multiple instances of the time threshold for selecting a lane wherein each lane placement has the time threshold set differently from one another; and

executing a lane merge operation based on the merge timing, the lane placement, or a combination thereof for guiding a user's vehicle to merge onto the lane different from currently traveled.

17. The non-transitory computer readable medium as claimed in claim 16 wherein determining the lane placement includes determining the lane placement based on a travel distance meeting or exceeding a distance threshold.

18. The non-transitory computer readable medium as claimed in claim 16 further comprising switching an operation mode based on the current location relative to a road segment.

19. The non-transitory computer readable medium as claimed in claim 16 further comprising adjusting a lane speed based on a travel context for controlling a travel speed, an obstacle speed, or a combination thereof.

20. The non-transitory computer readable medium as claimed in claim 16 wherein determining the buffer distance includes determining the buffer distance based on a physical distance between the obstacle locations greater than a user's vehicle size.
