Abstract:
The rise of smartphone applications within the transport sector has created new and exciting
opportunities to provide users with
a wide range of previously unavailable
information
services. The combination of journey planning applications and carbon calcul
ators, allows for
the provision of trip specific information regarding the potential environmental impact of
personal transport options. While these applications are readily available in the market place,
little in terms of scientific research has been und
ertaken to examine their influence on users.
This paper presents the results of a stated preference experiment examining influence of
carbon dioxide emissions information on user mode choice, as part of a survey undertaken
in the Greater Dublin Area in Nov
ember 2012. Acknowledging research findings arising from
the field of behavioural economics, this study recognizes that mode choices are also
influenced by factors other than the attributes presented to the user. In addition to standard
socioeconomic consi
derations, the influence of the respondents’ habitual transport behaviour
was incorporated into the multinomial logit model. Moreover, due to the issue of information
prese
ntation inherent in smartphone a
pplications, the effect of the respondents’
process
of
information assimilation
was examined. Results indicate that, for all non driving modes,
emissions play a significant role in the respondents’ mode choice, with reduced associated
emissions contributing to enhanced mode utility. The inclusion of habitua
l and information
processing variables was found to greatly improve upon the initial model in terms of
predictive power
