Abstract
The puget soud transportation panel (pstp) is the first application of a general-purpose urban travel panel survey in the united states. Following the dutch national mobility panel, it responds to needs for direct data on the effects of demographic characteristics and transportation conditions on household travel behavior in an urbanarea. The first-wave travel diaries for the 1, 687-household sample in the pstp were completed in 1989. The sample was stratified by travel mode and residence county. The panel was surveyed for attitudes and values in early 1990, and a second wave of travel diaries was scheduled for late 1990. This paper appears in transportation researchrecord no. 1285, Transportation forecasting 1990.
