MEASURING TIME LOSSES AT HIGHWAY BOTTLENECKS AND EMPIRICAL FINDINGS FOR THE CHESAPEAKE BAY BRIDGE

IN THIS PAPER A READILY IMPLEMENTABLE PROCEDURE IS DEVELOPED FOR MEASURING THE LENGTH OF TRAFFIC QUEUES AND TIME LOSSES FROM SEVERE HIGHWAY CONGESTION. THE METHOD IS THEN APPLIED TO AN ACTUAL SITUATION WHERE CONGESTION IS SO GREAT THAT 2-LANE TRAFFIC BACKUPS SEVERAL MILES IN LENGTH ARE FORMED. TIME LOSSES ARE CALCULATED FOR PAST OBSERVATIONS AND FORECAST FOR FUTURE YEARS. ALTHOUGH TIME LOSS IS A CRUCIAL ELEMENT IN HIGHWAY INVESTMENT ANALYSIS, LITTLE ATTENTION HAS BEEN DIRECTED TO THE DEVELOPMENT AND THE COMPARISON OF ALTERNATIVE MEASUREMENT TECHNIQUES. IN ADDITION, THERE ARE FEW INSTANCES IN TRAFFIC QUEUING LITERATURE WHERE SOPHISTICATED MEASUREMENT PROCEDURES ARE ILLUSTRATED WITH REAL-WORLD DATA. IN GENERAL, THE EXPERIENCE OF THE AUTHOR HAS BEEN THAT WHERE SOPHISTICATED MATHEMATICAL MODELS ARE USED THE DATA ARE HYPOTHETICAL AND WHERE REAL DATA EXIST THE TECHNIQUES USED ARE DEFICIENT.
