1996 Dallas-Fort Worth Travel Survey

The Dallas-Fort Worth Travel Survey encompassed households within the Consolidated Metropolitan Statistical Area of Dallas-Fort Worth. This includes all or part of Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Tarrant counties. The survey was conducted by the Applied Management & Planning in agreement with the North Central Texas Council of Governments (NCTCOG). Two main objectives drove the study. The main one was to update the existing data for NCTCOG's regional travel. Secondly, the survey aimed to provide new data elements to upgrade existing models. A total of 9,398 households was recruited for the study. Of these, 3,996 (42.5%) provided complete information. The survey revealed households' travel behavior preferences through a collection of information about household characteristics and travel using a unique "travel as an activity" approach. Respondents were asked to account for all of their time, including both trips and activities, during weekdays from February 19, 1996, to June 30, 1996.

1994 SEMCOG Household-Based Person Trip Survey

The Southeast Michigan Council of Governments contracted with the Applied Management & Planning Group to conduct a travel behavior survey of 7,361 households from March 28, 1994, to June 10, 1994.
