1. A computer program product including computer usable program code embodied on a computer usable storage medium, the computer program product comprising:
- computer usable program code for obtaining a first planned route to a destination for a first vehicle and for navigating the first vehicle to the destination;
computer usable program code for identifying a second vehicle within a threshold distance ahead of the first vehicle along the planned route of the first vehicle, the second vehicle having a speed of less than an expected speed of the first vehicle at that location along the first planned route;
computer usable program code for obtaining a second planned route being followed by the second vehicle and comparing the first and second planned routes to identify a shared segment of the first and second planned routes;
computer usable program code for computing a delay of the first vehicle to the destination as a function of the speed of the second vehicle along the shared segment and computing revised route information for the first vehicle on the basis of the delay; and
computer usable program code for automatically communicating the revised route information to an input/output device in the first vehicle or at a location remote from the first vehicle.

Abstract
A collaborative GPS navigation system and method enables nearby vehicles to share and compare planned route for improving navigation. While navigating along a planned route, a navigation device on a first vehicle may detect a specific, slower-moving second vehicle. The navigation device on the first vehicle may obtain the planned route of the second vehicle, compare the two planned routes to identify a shared route segment, and dynamically revise the planned route and route metrics according to the comparison.
