The Context

From Resource Paper, Timmermans

Data requirements are getting more complex But, response rates are dropping Can we design good user interfaces that help

increase interest and involvement, hence reducing respondent burden,

increase response rates, and data reliability

What are the Priorities for Electronic Surveys

Four Main Topics that were Identified:

• Simplification, or “Don’t make me think”– more intuitive and attractive design– Reduce respondent burden– “One size does not fit all” – Customize interfaces to recognize different

cultures, ages, languages.

Priorities, contd.

Recruitment and MotivationHow to bring users into the survey (what‘s new)Social exchange theory: “value” for respondent & Trust between respondent and interviewer

• Mixed ModesNecessary to reach many types of respondents -Combine phone mail, web, CATI, GPS– How to harmonize data from mixed modes

Priority Issues, contd.

• Privacy– Entirely new issues arise with multiple data

sources– With electronic data, information is collected and

stored without the users’ knowledge.– Respondents need a choice: “off” switch

Statement of Research Needs• Statement I: Develop interfaces that are congruent with the

mental models of how respondents think about transportation issues

• Statement II : Explore innovative means to both recruit and motivate respondents

_____________________________• Statement III: Address whether respondents understand the

privacy tradeoffs ( e.g. Cell phones and GPS- the spatial information they collect?

• Statement IV: Develop algorithms to synthesize and process data streams into usable measures, for modeling and other needs
