In the absence of a common methodology to measure the effects of community-based TravelSmart interventions, this paper addresses a series of issues that are critical for such an assessment. Based on a large-scale community-based TravelSmart intervention conducted in 2004 in the Melbourne suburb of Darebin with a target population of 30,000 households, the paper discusses the evaluation conducted by means of a panel survey before and after the intervention. Specific indicators and measurement techniques are presented that were used to assess travel behaviour change in general and the change in vehicle kilometres in particular. Special attention is drawn to sample size requirements of this ‘before’ and ‘after’ panel survey design, and to techniques available for the control for exogenous factors that may affect travel behaviour change independently from the TravelSmart intervention.
