Description

This paper presents how Paris regional household survey questionnaire is implemented in a web version and how user oriented design can improve the understanding of respondents and limit bias of a self-administered survey against a regular interview.

Abstract

The Enquete Globale Transport (EGT) is the household travel survey in Ile-de-France. In this survey some 18 000 households (43 000 persons) are interviewed in depth about the trips they made the day before the survey. The main aims of the survey are to monitor evolutions in mobility in the Ile-de-France region, and to serve as a database for modelling passenger transport demand.
Following a research into the methodology for this large-scale mobility survey (Research into New Methods for the Enquete Globale Transport in the Ile-de-France Region; ETC 2016, E. Kroes, P. Bonnel, L. Debrincat), decision was made to develop a specific software to: improve the quality and monitoring of the survey and to enable self-administered interviews. ONEPOINT was commissioned by STIF for the implementation of the EGT data collection tool.
This paper will explain how the Human Machine Interface (HMI) was designed toward User eXperience (UX) in the binding deadlines of the project (12 months for the complete tool but only 4 months to develop, from scratch, a demonstration of the online questionnaire): workshops, testing and feedback iterations.
This paper will then present some specifications of the online questionnaire, developed to substitute for the interviewers in the critical phase of answering to questions online, involving a comprehensive yet understandable collection of the trips schema:
• Guiding the respondent in a chronological approach, without explaining extensively the survey methodology;
• Adding flexibility to the time line to cope with different way of thinking;
• Making consistency checks in the least intrusive way;
• Integrating a discrete dunning process to ensure a more complete collection of trips.
The online questionnaire will be tested during a pilot survey late September 2017; final adjustment of the software will be implemented in the wake of pilot feedback, and the main release of the software will occur late 2017 so that the main survey starts in January 2018.
