1. A method for determining routes based on contextual risk comprising:
- generating, at a mobile device comprising a global positioning system (GPS) receiver, a processor, a network interface, and a display, candidate routes from a designated location to a destination based on available roadways and one or more fixed criteria;
determining a driver-associated risk for each of the candidate routes by weighting a behavior factor for a driver profile based on a frequency with which a user requesting the candidate routes traverses the candidate routes;
determining a contextual risk associated with each of the candidate routes based on at least dynamic environmental attributes that are retrieved from an external data source and weighted based on the driver-associated risk; and
displaying, on the display of the mobile device, the candidate routes on a map together with a representation of the determined contextual risk.

Abstract
Generating routes based on contextual risk includes receiving a destination and generating candidate routes to the destination from a designated location based on roadways available for routes and one or more fixed criteria. A contextual risk associated with each of the candidate routes is determined based on at least dynamic environmental attributes. The candidate routes are displayed on a map together with a representation of the determined contextual risk.

7. A navigation system comprising:
-
a global positioning system (GPS) receiver; a network interface; a processor configured to; generate candidate routes from a designated location to a destination based on available roadways and one or more fixed criteria; determine a driver-associated risk for each of the candidate routes by weighting a behavior factor for a driver profile based on a frequency with which a user requesting the candidate routes traverses the candidate routes; and determine a contextual risk associated with each of the candidate routes based on at least dynamic environmental attributes that are retrieved from an external data source and weighted based on the driver-associated risk; and a display configured to display the candidate routes on a map together with a representation of the determined contextual risk. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer program product for determining routes based on contextual risk, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor of a mobile device comprising a global positioning system (GPS) receiver, a network interface, and a display, to cause the processor to:
-
generate candidate routes from a designated location to a destination based on available roadways and one or more fixed criteria; determine a driver-associated risk for each of the candidate routes by weighting a behavior factor for a driver profile based on a frequency with which a user requesting the candidate routes traverses the candidate routes determine a contextual risk associated with each of the candidate routes based on at least dynamic environmental attributes that are retrieved from an external data source and weighted based on the driver-associated risk; and display, on the display of the mobile device, the candidate routes on a map together with a representation of the determined contextual risk. - View Dependent Claims (14, 15, 16, 17, 18)
