IMPACT OF TOLL CHANGES ON TRAFFIC AND REVENUE FOR BRIDGE AND TUNNEL FACILITIES

TRAFFIC AND TOLL DATA FOR SIX FACILITIES OF VARIED UTILIZATION, GEOGRAPHIC LOCATION, AND TOLL STRUCTURES WERE ANALYZED TO REVEAL TOLL-RELATED TRAFFIC LOSS. CONSIDERATION OF MONTHLY AND CUMULATIVE TRAFFIC TRENDS FOR COMPARABLE PERIODS BEFORE AND AFTER TOLL CHANGES DETERMINED THE NET PERCENTAGE IMPACT ON TRAFFIC OF EACH PRICE INCREASE. COMPUTATION OF THIS TRAFFIC LOSS IN TERMS OF EACH 1 PERCENT INCREASE IN TOLL, AVERAGED FOR THE SIX FACILITIES, YIELDED A SHRINKAGE RATIO FOR RIVER-CROSSING FACILITIES MINUS 17 PERCENT TRAFFIC LOSS FOR EACH 1 PERCENT INCREASE IN AVERAGE TOLL. FORECASTS WERE MADE FOR A SERIES OF FUTURE AVERAGE TOLLS, INCORPROATING REVENUE INCREASES WHICH ALLOW FOR THE 0.17 PERCENT LOSS RATIO. ALTOGETHER, REVENUE PRODUCTIVITY WAS SHOWN TO RANGE FROM ABOUT 65 TO 87 PERCENT OF THE PERCENTAGE INCREASE IN TOLLS. SEPARATE DETERMINATIONS WERE MADE FOR FACILITIES COMPETING WITH PARALLEL, LOW-TOLL CROSSINGS AND FOR TRUCK AND TRACTOR TRAILER TRAFFIC. TOLL DECREASES GENERALLY RESULTED IN SOME ADDITIONAL PATRONAGE, BUT THE TRAFFIC INCREASE HAS NOT BEEN NEARLY ENOUGH TO OFFSET THE REDUCTION IN TOLLS, WITH A CONSEQUENT LOSS IN TOLL REVENUE. /AUTHOR/
