Texas Department of Transportation Traffic Forecasting Practices (1235-5)

This report presents the results of a series of interviews conducted from 1989 to 1991 with district, division, and administrative staff of the Texas Department of Transportation (TxDOT). The purpose of these interviews was to obtain information on TxDOT transportation planning practices and procedures, to get an understanding of how the various districts and divisions viewed TxDOT planning practices, and to obtain opinions and perceptions about how well these practices were meeting the various planning needs of the Department. The interviews focused on the six research areas to be studied during this project: (1) state-of-the-art planning techniques, (2) traffic forecasting requirements, (3) traffic data collection and analysis, (4) rural traffic forecasting, (5) urban traffic forecasting, and (6) intercity route studies. Also, interviews were conducted with selected departments of transportation in other states to compare TxDOT practice with other state practices.
