Claim One:
1. A computer-implemented method of vehicle routing optimization by using a multivariate function for calculating a route value, the vehicle routing optimization configured to determine an optimal driving route for a driver of a vehicle traveling between a starting geographical location and a destination geographical location, the computer-implemented method comprising: accessing the starting geographical location of the vehicle; accessing the destination geographical location of the vehicle; accessing a model from an electronic storage, the model representing a road network comprising the starting geographical location and the destination geographical location, the model comprising a plurality of nodes representing intersections of the road network and a plurality of edges representing roadways of the road network, wherein each edge connects at least two nodes in the model and has a cost value for the vehicle to travel along the roadway represented by the edge; determining at least one driving route for the vehicle traveling between the starting geographical location of the vehicle and the destination geographical location of the vehicle, each driving route comprising an ordered set of edges, wherein each edge comprises a multivariate cost function for determining the cost value for the vehicle to travel along the roadway represented by the edge; determining the route value for each of the at least one driving routes based on the cost values for each edge in the at least one driving routes; and selecting the driving route from the at least one driving routes with the lowest route value; wherein the computer-implemented method is performed by a computer system that comprises one or more computing devices; wherein each multivariate cost functions comprises variables, the variables comprising at least a mapping data variable and at least one of the following variables: vehicle characteristic data variable, environmental data variable, driver data variable, and post intersection variable data.
