INTERCITY FREIGHT HAULAGE BY COMMODITY, SHIPPING DENSITY AND TYPE OF TRANSPORT, 1960

ATTEMPTS ARE MADE TO ALLOCATE 1960 PRODUCTION AND COMMODITY DATA UNDER THE DETAILED CODE PUBLISHED BY THE BUREAU OF THE BUDGET /BOB/ SO THAT COMPARISONS BETWEEN PAST, PRESENT AND FUTURE TRANSPORT STATISTICS CAN BE MADE. THE INTERSTATE COMMERCE COMMISSION /ICC/ CODE THAT IS COMPATIBLE WITH THE BOB CODE IS USED TO PREPARE TABLES ON COMMODITIES TRANSPORTED BY RAILROAD, INLAND WATERWAYS, DOMESTIC COASTLINE WATERWAYS, AND HIGHWAYS. THE DATA INDICATES THE PROPORTION OF COMMODITIES WHICH MAY BE HAULED IN VISIBLY FULL LOADS UNDER EXISTING GROSS WEIGHT LIMITATIONS. THE DATA MAY BE USED TO CALCULATE THE EXTENT OF USAGE WHICH MIGHT BE EXPECTED UNDER ANY GROSS WEIGHT LIMITATION. FIVE- AXLE VAN COMBINATIONS, TO STAY WITHIN LEGAL LIMITS, OPERATED WITH LESS THAN A VISIBLY FULL LOAD WHEN HAULING COMMODITIES OF SHIPPING DENSITIES 20 PCF OR MORE. TONNAGE WITH SHIPPING DENSITIES OF LESS THAN 20 PCF REPRESENTED 11.1 PERCENT OF THE TONNAGE WITH SHIPPING DENSITIES LESS THAN 50 PCF AND 5.0 PERCENT OF ALL COMMODITIES HAULED. SOME COMMODITIES WHICH HAVE BEEN COLLAPSED BY THE NEW ICC CODE INTO SUMMARY CODES HAVE REPORTED TONNAGES FROM 1,000,000 TO 17,000,000 TONS, AND APPEAR TO WARRANT SEPARATE REPORTING. THE INCREASE IN TRAILER LENGTH FROM 35 TO 40 FT COULD BE USED TO ADVANTAGE BY 11 PERCENT OF THE FIVE-AXLE COMBINATIONS HAULING COMMODITIES WITH SHIPPING DENSITIES OF LESS THAN 50 PCF UNDER GROSS WEIGHT LIMITS PRESENTLY SET FOR THE INTERSTATE HIGHWAY SYSTEM.
