Steve Gehrke (CEE PhD) - Application of Geographic Perturbation Methods to Residential Locations in the Oregon Household Activity Survey: Proof of Concept

Travel demand models have advanced from zone-based methods to favor activity-based approaches that require more disaggregate data sources. Household travel surveys gather disaggregate data that may be utilized to better inform advanced travel demand models and also improve the understanding of how nonmotorized travel is influenced by a household’s surrounding built environment. However, the release of these disaggregate data is often limited by a confidentiality pledge between the household participant and survey administrator. Concerns regarding the disclosure risk of survey respondents to household travel surveys must be addressed before these household-level data may be released at their disaggregate geography. In an effort to honor this confidentiality pledge and facilitate the dissemination of valuable travel survey data, this research: (i) reviews geographical perturbation methods that seek to protect respondent confidentiality; (ii) outlines a procedure for implementing one promising practice, referred to as the donut masking technique; and (iii) demonstrates a proof of concept for this technique on ten respondents to a household activity travel survey in the Portland metropolitan region. To examine the balance...

In honor of our 10-year anniversary, we’re trying something a little different. Instead of brief sessions that introduce you to a topic– we will be offering fifteen half-day workshops that focus on skill building and providing the tools to apply the latest research to practice. These will be hands-on, immersive learning experiences in a small classroom setting.

REGISTRATION

This event is a la carte, and pricing is per workshop. You may attend as few as one, or as many as four workshops.

• Half-Day Workshop (general admission): $95
• Half-Day Workshop (student rate): $50
