• Abstract:
  This research is concerned with ascertaining the value and effect of increased coded network detail on traffic assignment results. The Waco, Texas urban area (population of 132,000 during the O-D survey in 1964) was selected for use in the study, and three street system representations with greatly different degrees of detail were coded. Comparisons of traffic counts with the corresponding assigned volumes that resulted from each of three networks were analyzed with respect to screen line crossings, arterial streets, selected links, etc. Improved assignment results were not observed to accompany increased network detail. The networks with greater detail, however, presented extensive problems with respect to coding, data handling, adjustment and analysis.
