| 摘要： | This study uses commodity flows from the 1993 Commodity Flow Survey (CFS) together with Input-Output (I-O) coefficients to generate truck flows for the state of Wisconsin. Production and attraction rates in tons, for heavy truck mode only, were derived at the county level using employment for 28 economic sectors. The CFS, a joint product of the Bureau of Transportation Statistics and the U.S. Bureau of the Census, together with a private database developed for the state, TRANSEARCH, was used to derive the trip production rates. Economic based I-O software was used to derive the I-O coefficients at the state level in order to develop trip attraction rates. Annual tons at the county level were converted to daily truck trips using an average tons-per-vehicle load and days-per-year factor. |
