The Bureau of Transportation Statistics (BTS) is conducting a series of monthly surveys to monitor expectations of and satisfaction with the transportation system and to gather event, issue, and mode-specific information. The surveys will serve as an information source for the U.S. Department of Transportation (DOT) modal administrators, who can use them to support congressional requests and for internal DOT performance indicators. Overall, the surveys will support the collection of information on a wide range of transportation-related topics. This document contains the following information: background of the survey initiative; a detailed description of how sample respondents were selected for the survey; information on interviewing methods, household screening methods and methods for call attempts and callbacks; guidance on the use of weights for analysis; instructions for calculating standard error estimates; data collection methods.
