Abstract:
A client-server graphic routing system comprising:one or more maps route defining means instantiable to respond to driver interaction with a map to define a proposed pooling route and to store said pooling route, each proposed pooling route including a series of coordinates corresponding to a driver start, any intermediate and an end locations; request defining means instantiable to respond to passenger interaction to define a request for a pooling route, said pooling request including a pair of coordinates corresponding to passenger start and end locations; search means instantiable to search stored pooling routes for one or more pooling routes for said request, and including: linking means for deriving a series of vectors linking said driver defined pooling route coordinates; determining means for calculating the distance of closest approach from said passenger defined locations to said vectors; and comparison means for determining that said pooling route is suitable if said distance of closest approach is less than a pre-determined value; and addition means responsive to passenger selection of a suitable pooling route to include a passenger on said route.
