Workshop Synthesis: Making the transition to new methods for travel survey sampling and data retrieval

Abstract

Adopting new methods in large longstanding surveys, such as National Travel Surveys, is associated with specific challenges. Aside from methodological issues, the continuation of time series and data that is usable for many, are important concerns. Multi-mode surveys are becoming common place and new methods are run in parallel to established methods. This improves survey representativeness but there are new challenges, for example mode effects. The introduction and spread of smartphone use in surveys and emerging methods for recruiting survey participants will add to this complexity. As survey methods evolve, data post-processing and statistical methods have to keep up as well.
