“…Another study conducted in 48 US states showed that the users value road and traffic information as the most important feature of travel information systems [20]. As for information metrics, Brazil, Caulfied, and Rieser-Schüssler [21] studied the effectiveness of different methods of presenting transport-related carbon emissions. They found that the users demanded receiving carbon emissions in simple numerical form (i.e., Kilograms) [21].…”

Perceptions, Preferences, and Behavior Regarding Energy and Environmental Costs: The Case of Montreal Transport Users

Providing travel-related fuel and environmental information to transport users is becoming increasingly relevant. However, the impact of providing such information on users' travel behavior is yet to be determined. This research examined the perceptions and preferences related to the fuel consumption costs, greenhouse gas (GHG) social costs, and health-related air pollution costs, and the influence such information could have on travel behavior. Examining the case of Montreal transport users, the authors conducted a survey in which the respondents were asked general and stated preference questions. The respondents were found to be unaware of the energy and environmental footprints of their travel. Approximately 85% of the respondents were not able to estimate GHG social costs and health-related air pollution costs across different modes. The respondents generally overestimated these costs and they interestingly reported higher environmental costs for public transport (metro) compared to cars. They also preferred to receive such information in monetary units, and they were more comfortable in receiving the information through mobile applications over other tools/means. The research also found that fuel and environmental information influence respondents' travel decisions especially their route choices. Finally, the respondents would be willing to pay an average of 7 Canadian dollars/month in exchange for obtaining the information.Keywords: advanced traveler information system; fuel and environmental information; perceived travel costs; route/mode choice behavior; willingness to pay for information

“…Travellers may be compared to the average of the other participants (sometimes called the community), or to self-set goals. In this section, we discuss the activity system based on a number of reported studies of travel feedback apps (Gabrielli and Maimone 2013;Wells et al 2014;Broll et al 2012;Meloni and di Teulada 2015;Jariyasunant et al 2015;Brazil et al 2013). …”

With the continuous advancement of (mobile) ICT devices and applications, their impact on travel, activities and time use becomes more diverse. This holds in particular for apps developed for mobile devices (smartphones). In this paper, we argue that the effect of ICT on travel and activities should be analysed at the level of a single specific device or application, rather than for broad classes of ICT devices. We propose activity theory as a framework to analyse the impact of smartphone apps on travel and activities. Activity theory describes how subjects apply tools (such as apps) to work on an object and achieve an outcome that is in line with the subject's motive. The application of the tool is embedded in an activity system which includes a community, formal and informal rules and in which a division of labour exists. We apply activity theory to analyse the effects of Whatsapp and travel feedback apps, based on existing literature about these apps. The analyses suggest that the activity systems of each app differ greatly in terms of object, motive, outcomes, community and rules, with implications for their use and impact. Both apps have an impact on travel, but differ with respect to whether this effect is intentional. For both apps contradictions in the activity system can be identified, which may give rise to further development of the activity system. These seem, however, to be largest for travel feedback apps. Based on our exploration, we argue that quantitative research on the impact of apps should be complemented by qualitative research based on activity theory. In particular, activity theory may help to gain a better understanding of underlying mechanism by which apps influence travel, to strengthen the theoretical underpinning and interpretation of the results of quantitative research and to explore changes in the development and use of apps and their impact on travel behaviour.

“…Brail et al . observed a strong correlation between subjects' understanding of ways to reduce carbon emissions and the likelihood of altering mode choices. Combining revealed preference (RP) and SP data, Gaker and Walker used the latent class model to evaluate the VOG for transportation mode choices.…”

“…Firstly, most studies have identified travel cost and travel time as essential variables as well as intercity and urban traveling behavior. Policy implications (e.g., out‐of‐pocket cost, parking fee, and annual registration fee) have also been considered to investigate their effects on the promotion of low‐carbon mode usage . Secondly, carbon emissions from fueled and low‐carbon vehicles usually play a key role in proving the study's main hypothesis.…”

SUMMARYPlans are underway to introduce green transportation systems at Taiwan's famous scenic spot, Sun Moon Lake, to reduce carbon emissions. Carbon reduction effects after changing the current lake tour modes are assessed using a nested logit model with a stated preference survey, which investigated tourists' choice preferences. The empirical results reveal that the modes of electric bus, electric vehicle sharing, and bike are clustered in the same competitive group. Travel cost, in-vehicle travel time, and out-vehicle travel time are found to be statistically significant with the expected negative effects. In particular, the attribute of carbon reduction is only significant for green tourists, who are willing to pay US$ 3.5/kg of carbon saved. The result indicates that more efficient carbon reduction is possible by restricting the usage of gasoline vehicles rather than improving the service levels of low-carbon modes. Notably, the effect of parking charges on emission reduction is equal to the amount of carbon dioxide absorbed by 4511 trees per day. Copyright
