NTAS Study Overview

The purpose of this study is to examine the effects of local employment, shopping, transportation and neighborhood design on the distance people travel and the types of transportation they use.

Participation involves the following three steps:

1.Complete our Initial Household Questionnaire
We will use responses to this brief two minute questionnaire to select households to participate in the study. This step helps ensure the study will have participation from all types of households in your area. After you complete this step we will mail you the materials to complete steps 2 and 3.

2.Record your travel and activities on your assigned days
If you are selected to participate in the full study, we will mail you a Trip Log for each person in your household age 16 or older to record details about their travel and activities for three days. We will also mail you a Mileage Log for each household vehicle on which to record the odometer reading at the start and end of each day.

3.Report your travel information
After your designated survey period, use your trip logs and vehicle mileage logs to report travel information into our online survey. We will also ask you about your household composition, transportation resources, neighborhood, and residential location preferences. This step will take about 30 minutes to complete.

As an incentive, if you are selected to participate, when you complete the study we will mail your household a supermarket gift card worth $50.
