1. A method of assisting in selection of driving lanes and target speeds for vehicles, comprising the steps of:

  • a. receiving unprocessed lane-specific limited-access highway data from a traffic management center (TMC), or another data source;

    b. combining the unprocessed lane-specific limited-access highway data with data from a static database to create intermediate lane-specific limited-access highway data;

    c. generating processed predicted lane-specific limited-access highway data from the intermediate lane-specific limited-access highway data, said processed predicted lane-specific limited-access highway data conforming to a temporal and/or spatial data structure comprising barrels divided into zones, wherein boundaries of the barrels are defined by physical roadway configuration changes and permanent changes in regulatory use of the limited-access highway lanes and wherein boundaries of the zones are defined by changes in traffic conditions along the limited-access highway resulting from entry ramps and exit ramps and locations of motorist information devices and regulatory devices that provide changeable information and active traffic management control of the limited-access highway; and

    d. providing the processed predicted lane-specific limited-access highway data to one or more vehicles, wherein said processed predicted lane-specific limited-access highway data is visually or audibly presented in the one or more vehicles, said processed predicted lane-specific limited-access highway data enabling an in-vehicle guidance assist vehicle module of the one or more vehicles to select a preferred lane and target speed for the preferred lane using a copy or a subset of the static database.
