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 freeway transportation management centers or traffic management centers, process and convert the unprocessed information to a form that assists in the selection of driving lanes and target speeds for vehicles, and communicate the processed information to the vehicles by suitable means. The Guidance Assist Vehicle Module combines the processed information with information from the vehicle and the driver including the information on appropriate lane changes and speed commands to the vehicle.
