Abstract

The 1980 U.S. Census of Population and Housing will include the largest source of urban transportation data ever available for a single point in time. To properly use these data requires that planners understand the difference between census definitions and those commonly used in transportation. This paper describes those differences as well as the data that will not be included in the census. It recommends methods of local data collection that can supplement the census data to complete the measurement of total travel. Finally, it proposes a method of keeping the census commuting data up to date without extensive inventory data for 1980. The method is suitable for small urban areas as well as large metropolitan regions.
