In general, the present invention relates to route optimization/prediction. In one embodiment, the present invention provides visibility to future predicted traffic situations, based on all reserved routes in a system at a given point in time. This allows city planners, for example, to know where traffic will be to adjust traffic flow accordingly. Additional value comes into play by being able to calculate and publish aggregated savings from using this system, such as driver time, mileage, and gas. This information may be added to a database and made available to individuals via their GPS. In a typical implementation, a request for a route is received from a requester. Based on the request, an optimized route and a potential position of the requester within the optimized route are determined and then proposed to the requester. The requester can then select an option from the proposal.
