Origin-Destination Data Collection Technology

Abstract

Traditionally, the collection of origin-destination data through travel surveys has been a labor-intensive undertaking. Field researchers, armed with clipboards, stopped motorists as they traveled or visited residents in their homes to ask questions about the origins, destinations, purposes, and modes of travel. Technological improvements have led to more cost-effective survey methods that reduce the need to conduct intercept, in-person, and mail-based surveys. This chapter organizes and discusses recent trends in travel surveying based on whether they generate self-reported or observed travel data. The results suggest that these techniques are best used as a valuable supplement to traditional data generation methods or as a low cost alternative in situations where snapshots of travel activity will suffice. Future travel surveying efforts are likely to include a mix of traditional strategies and emerging technologies as the travel survey community continues to adapt to emerging technologies.
