Navigation system with parking lot integrated routing mechanism and method of operation thereof

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

identifying a physical location;

selecting a starting point based on the physical location;

selecting a destination;

identifying a destination lot encompassing the destination and including multiple access points;

selecting a specific access point from multiple access ways based on a route selection criteria including a set of criteria ordered according to priority of each criterion in evaluating the multiple access ways; and

calculating with a control unit a vehicle travel route from the starting point to the destination with the vehicle travel route traversing across a portion of the destination lot and through the specific access point for traversing the vehicle travel route with a single vehicle.

2. The method as claimed in claim 1 wherein:

selecting a specific access point includes selecting a preferred entry point into the destination lot; and

calculating the vehicle travel route includes calculating the vehicle travel route through the preferred entry point.

3. The method as claimed in claim 1 further comprising:

identifying a destination-lot hazard within the destination lot and the destination-lot hazard requires a cautionary attention; and

generating an arrival warning based on a time of day when the cautionary attention is required.

4. The method as claimed in claim 1 wherein:

identifying the destination lot includes identifying the destination lot having operation hours and a traffic flow rate of vehicles traveling through the destination lot; and

further comprising:

selecting a suggested leaving time when the traffic flow rate exceeds a predetermined amount than at a departure time.

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

identifying a physical location;

selecting a starting point based on the physical location;

identifying a start lot associated with the starting point including multiple access ways;

selecting a preferred exit-point from the multiple access ways based on a route selection criteria including a set of criteria ordered according to priority of each criterion in evaluating the multiple access ways;

selecting a destination;

identifying a destination lot encompassing the destination and including multiple further access ways;

selecting a preferred entry point from the multiple access ways based on the route selection criteria; and

calculating with a control unit a vehicle travel route from the starting point to the destination with the vehicle travel route traversing out of the start lot and across a portion of the destination lot through the preferred exit-point and the preferred entry point for traversing the vehicle travel route with a single vehicle.

6. The method as claimed in claim 5 further comprising:

identifying an origin-lot hazard within the start lot and the origin-lot hazard requires a cautionary attention; and

generating a departure warning based on a time of day when the cautionary attention is required.

7. The method as claimed in claim 5 further comprising:

identifying a first route-hazard geographically near the start lot and the first route-hazard requires a cautionary attention; and

generating a route start warning based on a time of day when the cautionary attention is required.

8. The method as claimed in claim 5 wherein:

identifying a last route-hazard geographically near the destination lot and the last route-hazard requires a cautionary attention; and

generating an approach warning based on a time of day when the cautionary attention is required.

9. The method as claimed in claim 5 further comprising identifying a parking stall within the destination lot with a distance between the destination and the parking stall is minimal.

10. A navigation system comprising:

a location unit configured to identify a physical location;

a control unit, coupled to the location unit, configured to:

select a starting point based on the physical location;

select a destination;

identify a destination lot encompassing the destination and including multiple access points;

selecting a specific access point from multiple access ways based on a route selection criteria including a set of criteria ordered according to priority of each criterion in evaluating the multiple access ways; and

calculate a vehicle travel route from the starting point to the destination with the vehicle travel route traversing across a portion of the destination lot and through the specific access point for traversing the vehicle travel route with a single vehicle.

11. The system as claimed in claim 10 wherein the control unit is configured to:

select a preferred entry point into the destination lot; and

calculate the vehicle travel route through the preferred entry point.

12. The system as claimed in claim 10 wherein the control unit is configured to:

identify a destination-lot hazard within the destination lot and the destination-lot hazard requires a cautionary attention; and

generate an arrival warning based on a time of day when the cautionary attention is required.

13. The system as claimed in claim 10 wherein the control unit is configured to:

identify the destination lot having operation hours and a traffic flow rate of vehicles traveling through the destination lot; and

suggest a suggested leaving time when the traffic flow rate exceeds a predetermined amount than at a departure time.

14. The system as claimed in claim 10 wherein the control unit is configured to:

identify a start lot associated with the starting point including multiple further access ways;

select a preferred exit-point from the multiple further access ways based on the route selection criteria;

select a preferred entry point into the destination lot from the multiple access ways based on the route selection criteria; and

calculate the vehicle travel route from the starting point to the destination with the vehicle travel route traversing through the start lot and the destination lot through the preferred exit-point and the preferred entry point.

15. The system as claimed in claim 14 wherein the control unit is configured to:

identify an origin lot hazard within the start lot and the origin-lot hazard requires a cautionary attention; and

generate a departure warning based on a time of day when the cautionary attention is required.

16. The system as claimed in claim 14 wherein the control unit is configured to:

identify a first route-hazard geographically near the start lot and the first route-hazard requires a cautionary attention; and

generate a route start warning based on a time of day when the cautionary attention is required.

17. The system as claimed in claim 14 wherein the control unit is configured to:

identify a last route-hazard geographically near the destination lot and the last route-hazard requires a cautionary attention; and

generate an approach warning based on a time of day when the cautionary attention is required.

18. The system as claimed in claim 14 wherein the control unit is configured to identify a parking stall within the destination lot with a distance between the destination and the parking stall is minimal.
