This paper outlines a new approach to reducing car use in order to address
environmental concerns. The individual action program, known as Travel Blen
ding((R)), involves participating households being sent a series of four ki
ts, containing information booklets and travel diaries, over a nine-week pe
riod. The travel diaries are analysed and a summary of the household's trav
el patterns, and the emissions produced by their vehicles, is sent back in
a subsequent kit along with suggestions explaining how they could reduce ve
hicle use. Households complete another set of travel diaries after four wee
ks and these are analysed so that a comparative summary can be returned to
the household with the final kit. The paper describes results from two Aust
ralian studies. The first, a pilot study, involving about 50 individuals, w
as undertaken in Sydney, Australia. The second study involved about 100 hou
seholds from Adelaide, Australia. Quantitative results from the Adelaide st
udy indicate about a 10% reduction in car driver kilometres with a slightly
higher percentage reductions in car driver trips and total hours spent in
the car. These results, while very encouraging, must be interpreted cautiou
sly. Further research will be required to explore the generalisability and
magnitude of the effect of the Travel Blending((R)) Program on travel behav
iour. (C) 2001 Elsevier Science Ltd. All rights reserved.
