Prediction for lane guidance assist
First Claim
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.

Abstract
The automated lane management assist method, data structure and system receive unprocessed lane-specific limited-access highway information, including lane use and speed limits, from traffic detectors in the roadway or from other sources, process and develop predicted information from these sources and substitute the predicted information for the current information where appropriate, thus improving the timeliness of the information in a form that assists in the selection of driving lanes and target speeds for vehicles, including in partially and fully automated vehicles, and communicate the processed predicted information to the vehicles by suitable means.

14. A non-transitory computer-implemented roadway zone based data structure for expressing predicted traffic parameters, incident data, regulatory data and toll information in geographical segments that are appropriate for limited-access highway lane selection and target speed selection for the chosen lanes, said data structure comprising:
-
a. at least one interface for receiving unprocessed lane-specific limited-access highway data from a traffic management center; and b. a processor coupled to the at least one interface, wherein the processor receives the unprocessed lane-specific limited-access highway data through the at least one interface, processes the unprocessed lane-specific limited-access highway data, generates 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 transmits processed predicted lane-specific limited-access highway data to at least one vehicle in a form appropriate for limited-access highway lane selection and target speed selection for the chosen lanes, wherein the processed predicted lane-specific limited-access highway data is visually or audibly presented in the at least one vehicle. - View Dependent Claims (15, 16)
