THE VAN WYCK EXPRESSWAY EXPERIMENT
A STUDY WAS CONDUCTED ON A SHORT SECTION OF THE VAN WYCK EXPRESSWAY IN NEW YORK CITY TO DETERMINE THE ADVISABILITY OF PROCEEDING WITH A MORE COMPREHENSIVE STUDY TO ASCERTAIN THE NEED FOR THE DESIGN OF A TOTAL SURVEILLANCE AND CONTROL SYSTEM FOR IMPROVING OVERALL OPERATIONS ON THE EXPRESSWAY. RAMP METERING ON A FIXED-TIME BASIS AND RAMP CLOSURE WERE INCLUDED. TRAFFIC WAS DIVERTED VIA A SERVICE ROAD, FROM AN ON-RAMP THAT WAS OBSERVED TO BE CAUSING CONGESTION, TO A PAIR OF RAMPS CONTROLLED BY FIXED TIME SIGNALS. WHILE HOPING TO ACCESS THE RELATIONSHIP OF ACCIDENTS TO CONGESTED OPERATIONS, THE STUDY PERIOD WAS TOO SHORT TO APPRAISE THE PROJECT'S EFFECTS ON ACCIDENT RATES. A STATISTICAL ANALYSIS WAS MADE OF TRAVEL TIME DATA ON THE EXPERIMENTAL SECTION BY TIME-OF-DAY STRATIFICATION, OVERALL TRAVEL TIME REDUCTIONS ON THE ORDER OF 20 TO 30% WERE REALIZED FOR THE EXPRESSWAY AND SERVICE ROAD, RESPECTIVELY. IMPROVEMENTS SHOW THAT A CONTROL SYSTEM OVER THE ENTIRE FREEWAY THAT WOULD BE RESPONSIVE TO VARIATIONS IN TRAFFIC STREAM BEHAVIOR WOULD LIKELY PRODUCE LOWER ACCIDENT RATES AND A HIGHER LEVEL OF SERVICE. /AUTHOR/
