Abstract

A method for navigation includes receiving in a mobile computing device (24) a designation of an origin (32, 92) and a destination (34, 94) of an itinerary of a user of the device. An optimal primary route (96) is computed from the origin to the destination. Multiple points of interest (40, 98, 100) are identified in proximity to the optimal primary route. A respective first optimal sub-route (42) is computed between the origin and each of the points of interest, and a respective second optimal sub-route (44) is computed between the destination and each of the points of interest. One or more alternative routes (102, 104) from the origin to the destination via one or more of the points of interest are presented to the user on the mobile computing device, by combining the respective first and second optimal sub-routes computed for the one or more of the points of interest.
