Does green make a difference: The potential role of smartphone technology in transport behaviour

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. Unlike previously available information sources, smartphone technology enables users to access individual and trip specific information both pre-trip and en route in real-time. The combination of journey planning applications and carbon calculators, allows for the provision of trip specific information regarding the potential environmental impact of personal transport options. While these applications are becoming more readily available in the market place, little in terms of scientific research has been undertaken 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 November 2012. Acknowledging research findings arising from the field of behavioural economics, this study recognises that mode choices are also influenced by factors other than the attributes presented to the user. 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.
