Abstract
A method involves accelerating the electronic determination of high quality solutions to routing problems by utilizing determined optimized time windows for precomputing optimal path matrices to reduce computer resource usage. The use of traffic windows defined based on changes in rates of change of speeds for traffic on road segments allows for more rapid determination of a set of one or more high quality solutions as compared to requiring on-demand, in-process determination of a shortest path for a particular time during comparison of paths or routes performed as part of a process for determining high quality solutions to the routing problem.
