Reducing the burning of fossil fuels for transport will help reduce the rate of climate change and the severity of the impact of climate change. The alternatives to private motor vehicles include active travel modes such as walking, cycling and use of public transport. While simultaneously reducing carbon dioxide emissions and traffic congestion, active transport leads to increased levels of ph...

How staff and students travel to university can impact their physical activity level. An online survey of physical activity and travel behaviour was conducted in early November 2012 to inform planning of physical activity and active travel promotion programs at the University of Sydney, Australia as part of the "Sit Less, Move More" sub-committee of the Healthy University Initiative, and as bas...

Transport models adopt simplified descriptions of travel behaviour and are used to make forecasts when evaluating transport policy measures (e.g. road pricing, traffic management, and traffic information). This research investigates travel choice behaviour on roads and aims to (i) improve our fundamental understanding of decision processes between interacting agents (drivers), with a final goal...

The Cyber World has become a most important part of our everyday lives. We spend an increasingly significant portion of our lives in it and use it to communicate with friends, acquaintances, loved ones, and business associates. We make use of our computers and Internet connectivity to look for and purchase all kinds of goods and services. We make airline and other travel reservations through th...

This paper explores a paradox: negative correlations between indicators of mobility (such as VMT) and productivity (such as GDP), and positive correlations between mobility constraints (higher road use prices or traffic congestion) and productivity. These relationships contradict common assumptions that policies and projects that increase vehicle travel (roadway expansions and lower road user p...

The paper tests ‘twoalternative specifications for the opportunity cost of time in travel cost models. The standard travel cost survey design is enriched to include a contingent valuation type question about peoples’ willingness to accept compensation to forgo a precisely defined recreational experience. It is hypothesized that individually revealed value of time more appropriately reflects the...

Abstract Perceived travel times of travelers are usually longer than actually realized times, implying that passengers’ experience time savings is different from objectively calculated savings. This study provides additional empirical evidence on this topic, by comparing the perceived reported in an (online) survey with their corresponding actual in-vehicle Automatic Vehicle Location (AVL) data...

Accessibility of travel may be better understood if psychological factors underlying change in travel behavior are known. This paper examines older (65+) travelers' motives for changing their travel behavior. These changes are grounded in critical incidents earlier encountered in public-transport travel. A scientific framework is developed based on cognitive and behavioral theory. In 29 individ...
