IMPACT OF 50, 55 OR 60 M.P.H. STATEWIDE SPEED LIMIT

THIS ANALYSIS WAS COMPLETED IN ORDER TO DETERMINE THE PROBABLE IMPACT THAT A STATEWIDE SPEED LIMIT MIGHT HAVE ON GASOLINE CONSUMPTION IN THE STATE OF MICHIGAN. FOR THE PURPOSES OF THIS STUDY IT WAS ASSUMED THAT THE MOST LIKELY SPEED LIMIT WOULD BE 50 M.P.H. ADDITIONAL ANALYSES WERE ALSO COMPLETED FOR BOTH A 55 M.P.H. SPEED LIMIT AND ALSO A 60 M.P.H. SPEED LIMIT. THREE BASIC DATA SOURCES WERE USED TO COMPLETE THIS ANALYSIS. THEY WERE: (1) 1972 U.S. DEPARTMENT OF TRANSPORTATION, TABLE T.A. 1 FOR MICHIGAN; (2) TEXT BOOK BY ROBLEY WINFREY ENTITLED ECONOMIC ANALYSIS FOR HIGHWAYS; AND (3) MICHIGAN DEPARTMENT OF STATE HIGHWAYS AND TRANSPORTATION REPORT #66 ENTITLED SPEED REPORT, APRIL 1972. ANALYSIS COMPLETED IN THIS DOCUMENT IS INTENDED SOLELY AS AN INTITIAL INQUIRY. THE RESULTS OBTAINED ARE BASED UPON SEVERAL JUDGEMENTAL ASSUMPTIONS AND USE OF THIS INFORMATION MUST BE BASED UPON FULL KNOWLEDGE OF THESE ASSUMPTIONS. /AUTHOR/
