"Because of the FTA directive, transit agencies have an even stronger interest than before in identifying which survey methods minimize costs while still gathering high-quality data," said Dr. Nixon. "They have no reasonable way to determine the best method, so MTI took on that task. Although it might seem that online surveys could be a good method in a connected society, we found that paper surveys may still be the best option for most survey types."
To design an appropriate experimental survey for this study, the research team conducted interviews with both transit survey experts and agency staff managing the surveys.
The 81-page report includes several tables that detail the results from each tested method, as well as copies of the survey instruments. The study findings suggest several general recommendations for current survey practice:
Online surveys administered via an invitation distributed on the transit vehicle are not a good option.
The old-fashioned, low-tech paper survey may still be the best option for many bus passenger surveys.
Changes in survey results that accompany changes in survey methods should be interpreted with caution.
Using a new survey method, especially one relying on more complex technologies, may create unexpected glitches.
The analysis focused on several key questions:
Did return and completion rates vary by survey mode?
Did the percentage of respondents skipping or providing unusable information for particular questions or question types vary by survey mode?
Did responses vary across socio-demographic characteristics by survey mode?
Did responses vary depending on passenger travel behavior by survey mode?
Did customer satisfaction levels vary by survey mode?

ABOUT THE MINETA TRANSPORTATION INSTITUTE The Mineta Transportation Institute (MTI) conducts research, education, and information transfer programs regarding surface transportation policy and management issues, especially related to transit. Congress established MTI in 1991 as part of the Intermodal Surface Transportation Efficiency Act. MTI won national re-designation competitions in 2002, 2006 and 2012. The Institute is funded through the US Department of Transportation, the US Department of Homeland Security, the California Department of Transportation, and public and private grants. The internationally respected members of the MTI Board of Trustees represent all major surface transportation modes. MTI, the lead institute for the nine-university Mineta National Transit Research Consortium, is affiliated with San Jose (CA) State University's College of Business. Visit transweb.sjsu.edu
