ICT and accessibility: Research synthesis and future perspectives
No full textNumerous studies have been conducted on the impact of various forms of information and communication technologies (ICTs) on activity patterns and travel demand, and many impacts have been widely recognized since the early 1970s (e.g., see Mokhtarian et al., 2006; Aguiléra et al., 2012; van Wee et al., forthcoming, for overviews of literature). Research on ICT and travel behaviour is receiving increased attention, as reflected by special issues of Transportation Research Part A (see Kwan et al., 2007) and the Journal of Transport Geography (Lyons, 2009). The principal research concern, particularly in the field of transport economics, is still the opposition between complementarity or even generation effects and substitution effects: do ICTs stimulate or reduce travel demand? (Aguiléra et al., 2012). The answer is still fairly unclear, even though the idea of complementarity or generation dominates (Mokhtarian, 2009). In contrast to literature on the impact of ICT on travel and activity behaviour, literature on the impact of different forms of ICT on accessibility is relatively scarce. Job accessibility is probably still the most frequently researched topic in the area of ICT and accessibility. Examples include Muhammad et al. (2008) who developed potential accessibility models that integrate job accessibility in virtual and physical space, and Shaw and Yu (2009) who extended a space–time geographic approach of individual activities by including the virtual space. Several review articles on accessibility measures have been published before (see section 3.2), but to our knowledge a comprehensive overview of the impact of ICT on accessibility does not exist yet. This chapter aims to fill this gap and provide a systematic overview of potential impacts of ICT on accessibility, using the four components of accessibility as distinguished by Geurs and van Wee (2004), that is, the land-use, transport, temporal and individual components. Furthermore we address the gaps in the literature relating to the impact of ICT on travel behaviour and accessibility.1 Note that we focus on passenger transport and exclude ICT’s impact on goods transport and access to ICT
Sustainable Energy Technology Acceptance: A psychological perspective
No full textSustainable energy systems are designed to overcome the large problems resulting from current fossil fuel use, such as climate change, air pollution and energy insecurity. Citizens’ opinions and responses are crucial to the successful implementation of new technologies. This thesis explains public acceptance from a psychological perspective. A framework is developed and used to explain the acceptance of hydrogen refueling facilities. The variable trust is further explored for carbon storage acceptance.Transport van LogisticsTechnology, Policy and Managemen
Intermodal Freight Transport on the Right Track?: Environmental and economic performances and their trade-off
No full textThis dissertation aims to evaluate environmental and economic performances of an intermodal freight transport system and to estimate the trade-off between CO2 emissions, wich is epresented as an indicator of environmental performance, and freight costs, which ndicate the economic performance of the intermodal freight system. The truck-only system is always regarded as the counterpart of the intermodal freight system in this dissertation. To examine the environmental performance of the intermodal freight system, CO2 emissions generated from all the processes in the intermodal chain, such as pre- and post-haulage, long distance haulage, and transshipment, are estimated considering different sources that generate electricity and transmission loss of electricity (Chapters 3 and 4). To examine the economic performance of the system, two approaches are considered: (1) finding the intermodal breakeven distance for which the intermodal system is more competitive than the truck-only system (Chapter 5); (2) examining the economies of scale in the intermodal network and finding the route/system choice that minimizes the total freight transportation costs (Chapter 6). Finally, this dissertation attempts to find the trade-off between CO2 emissions (representing the environmental performance) and freight transportation cost (representing the economic performance) (Chapter 7).Transport and infrastructureOTB Research Institute for the Built Environmen
