Abstract
This project aims to investigate data quality trends and evidence for Household Travel Surveys (HTS). HTS are used to obtain travel patterns from all infrastructure users, and may include information about origins and destinations (i.e., from/to where they go), modes of transport (i.e., how they get there), and activities that motivate the travel. Over the decades, survey response rates have been rapidly declining, resulting in issues like lack of representativeness and biases in surveys. Our goal is to define and examine what has been found with regard to representativeness and bias in HTS. I have been involved in cataloging and synthesizing the existing literature on HTS representativeness and nonresponse bias as well as supporting the instrument coding and quantitative analyses steps. Overall, we find significant differences in findings around representativeness and bias in HTS, due in large part to differences in definitions and methods. During the course of this presentation, I will share the synthesized findings from this investigation.
