Title: SOME MEASURABLE QUALITIES OF TRAFFIC SERVICE INFLUENCED BY FREEWAYS
Accession Number: 00201113
Record Type: Component
Abstract: BEFORE AND AFTER STUDIES WERE CONDUCTED BETWEEN SEATTLE AND TACOMA, WASHINGTON ON A CONGESTED HIGHWAY, AND ON THE 6 LANE FREEWAY THAT REPLACED IT. DATA ON TRAVEL TIME, OVERALL SPEED, DELAY, FUEL CONSUMPTION, DISTANCE AND VOLUME WERE COLLECTED. THE EFFECT OF OPERATING SPEED AND TRAFFIC VOLUME ON TRAVEL TIME AND FUEL CONSUMPTION ARE ANALYZED, AND THE ECONOMICS OF VEHICLE OPERATION ARE INVESTIGATED. IT IS CONCLUDED THAT WHEN THE FREEWAY BYPASS ROUTE AND THE OLDER BUSINESS ROUTE ARE COMPARED THERE IS ALWAYS A SAVINGS IN TRAVEL TIME, EVEN WHEN THE FREEWAY DISTANCE IS 12 PERCENT GREATER THAN THE OLDER ROUTE, BUT THERE MAY NOT BE AN ECONOMIC BENEFIT IN FUEL CONSUMPTION, DEPENDING ON ROUTE DISTANCES, CHARACTER OF SPEED CHANGE AND VEHICLE TYPE. BY COMBINING THE TRAVEL TIME SAVINGS AND THE FUEL CONSUMPTION, THE OPTIMUM ECONOMIC SPEED OF OPERATION IS INDICATED.
