METHOD TO SYNTHESIZE A FULL MATRIX OF INTERDISTRICT HIGHWAY TRAVEL TIMES FROM CENSUS JOURNEY-TO-WORK DATA

The 1980 census Urban Transportation Planning Package (UTPP) is a large-scale source of observed travel times derived from the journey-to-work data. Plans for the 1990 census indicate that work trip times will again be collected. These data are incomplete, however, in that most cells in the interdistrict matrix have no census travel time observation. This paper explores the accuracy and usefulness of census travel time data versus survey- and network-based methods and airline distance approaches at the minor civil division (MCD) level of analysis. A promising technique to extract and edit the census data and to synthesize the missing observations is developed.
