INVESTIGATION OF LANE OCCUPANCY AS A CONTROL VARIABLE FOR A SAFETY WARNING SYSTEM FOR URBAN FREE-WAYS

LANE OCCUPANCY WAS EVALUATED AS A TRAFFIC VARIABLE FOR DIGITAL COMPUTER CONTROL OF A SAFETY WARNING SYSTEM FOR URBAN FREEWAYS. PERFORMANCE CHARACTERISTICS WERE STUDIED OF MEASURED LANE OCCUPANCY AS AN INDICATOR OF SHOCK WAVES RESULTING FROM FREEWAY INCIDENTS. A CONTROL STRATEGY WAS DEVELOPED, PROGRAMMED, AND EVALUATED FOR DIGITAL COMPUTER OPERATION OF THE WARNING SYSTEM. COMPARISONS WERE MADE WITH ENERGY AS A CONTROL VARIABLE. BASED ON THE RESULTS OF THIS RESEARCH A NEW CONTROL ALGORITHM WAS DEVELOPED INCORPORATING THE BEST PERFORMANCE FEATURES OF OF BOTH ENERGY AND LANE OCCUPANCY.
