Abstract:

Effective trip speeds were calculated from reported mean travel times from the 1980 Urban Transportation Planning Package and the 1990 Census Transportation Planning Package special census tabulations for six urban areas: Houston, Dallas-Fort Worth, Philadelphia, Boston, San Francisco, and Atlanta. Comparison methodology is presented in a detailed pilot study, followed by an analysis of the six urban area comparisons. Data were combined in a pooled comparison for three modes of transportation: drive alone, carpool, and transit. The data indicate a slight decrease in effective trip speed of less than 1 mph for those who drove alone to work, while there was a slight increase in overall trip speed for those who reported using a carpool or pub1ic transportation for at least one leg of the journey to work. Also, the census samples indicated a wide variability of ± 12 mph for those who drove alone or carpooled, while transit users varied slightly less in their responses, 9 mph. Moreover, trip speed changes by orientation (radial, circumferential, and reverse flow) seem to be stabilized from 1980 to 1990, which indicates that transportation systems in larger metropolitan areas are keeping abreast of demands.
