The COVID-19 pandemic and the consequent travel restrictions have had an unprecedented impact on the air travel market. However, a rigorous analysis of the potential role of safety perceptions and attitudes towards COVID-19 interventions on future air passenger choices has been lacking to date. To investigate this matter, 1469 individuals were inte...

Planning and managing an energy system in a district require a comprehensive understanding and accurate modelling of people's occupancy and circulation among multiple buildings. Due to the lack of occupancy modelling tools for district scale analysis, energy models still use simplified occupancy patterns provided in building codes and standards. Ho...

It is now recognised in travel behaviour research that travel time can be, and in fact is, used to undertake productive, work-related activities. The phenomenon, also referred to as travel-based multitasking, has in recent years been compounded by the proliferation and sophistication of mobile information and communication technologies (ICT). Accor...

After the fall of communism, the Emerging European Economies inherited a transport sector characterised by low car ownership rates, heavy reliance on public transport, and a sparse infrastructure network. This chapter presents a systematic review of the evolution of transport policy through the region’s EU accession, the 2008 financial crisis, and...

Travel-based multitasking, i.e. using travel time to conduct enjoyable and/or productive activities, is the subject of an increasing number of theoretical and empirical studies. Most existing studies focus on modelling the choice of which activities people conduct while travelling, and a limited number of papers also focuses on their duration. The...

In light of the growing availability of big data sources and the essential role of socio-demographic information in travel behaviour and transport demand modelling more broadly, the enrichment of socio-demographic attributes for anonymous big datasets is a key issue that continues to be explored. The common shortcoming of existing socio-demographic...

The ability to accurately model and predict timing and duration of activities for different individuals is essential for successful and widespread Demand Side Response (DSR) policies, especially in the residential sector. Understanding what people do during the day and what factors influence their activity participation decisions is important for p...

Driven by the necessity to increase utilisation of the existing networks and accommodation of volatility in renewable energy generation, the energy sector is undergoing a shift from an unconstrained infrastructure expansion to accommodate growth in demand towards demand management strategies. Such strategies, for example nudging demand using incent...

The COVID-19 pandemic and associated travel restrictions have created an unprecedented challenge for the air transport industry, which before the pandemic was facing almost the exact opposite set of problems. Instead of the growing demand and need for capacity expansion warring against environmental concerns, the sector is now facing a slump in dem...

Information and communication technology, or ICT, has rapidly emerged as an integral element of everyday life, interacting in an essential manner with activity and travel patterns. Three decades of research on the interactions among ICT, activity decisions and travel choices have shown the elaborate, disruptive, and often unexpected ways along whic...

Building occupancy, which reflects occupant presence, movements and activities within the building space, is a key factor to consider in building energy modelling and simulation. Characterising complex occupant behaviours and their determinants poses challenges from the sensing, modelling, interpretation and prediction perspectives. Past studies ty...

Travel-based multitasking, also referred to as travel time use, is now a well-established concept, whose existence is supported by the technological trajectories, with mobile information and communication technologies (ICT) and vehicle automation working together to allow travel time to be more productive and enjoyable. Despite existence of reviews...

The sophistication in the demand management approaches in both transport and energy sectors and their interaction call for modelling approaches that consider both sectors jointly. For agent-based microsimulation models of travel demand and energy consumption, this implies the necessity to ensure consistent representation of user behaviour with resp...

Driverless cars are expected to have the advantage of lifting requirements for driver’s license ownership and fitness to drive. As such they may offer improved accessibility and mobility for those currently unable to drive, e.g., the elderly and disabled [1], [2]. Despite the postulated benefits, the role of driverless cars in future transport syst...

The growing availability of geotagged big data has stimulated substantial discussion regarding their usability in detailed travel behaviour analysis. Whilst providing a large amount of spatio-temporal information about travel behaviour, these data typically lack semantic content characterising travellers and choice alternatives. The inverse discret...

Recent developments in mobile information and communication technologies (ICT), vehicle automation, and the associated debates on the implications for the operation of transport systems and for the appraisal of investment has heightened the importance of understanding how people spend travel time and how productive they are while travelling. To dat...

Purpose The European Union offers support mechanisms to help small and medium sized enterprises (SMEs) to innovate and grow. Given the substantial contribution of SMEs to national economies, the present paper explores what factors tend to be associated with the success of EU-supported innovation by SMEs in Poland during its early post-accession pe...

Understanding of the interactions between Information and Communication Technologies (ICT) and physical mobility is a major area of research with practical applications in a number of fields. Very little, however, is known regarding how these relationships vary on a cross-national basis, including across countries at different stages in development...

Information and communications technology (ICT) is rapidly evolving and is penetrating more and more aspects of people’s everyday lives, including how they travel. This study establishes the current state of knowledge regarding the relationship between ICT and physical mobility, and gives specific guidance for avenues of future research.

This report contains the findings of the audit and peer review of research on values of travel time savings and reliability. It covers: 1. the procedures adopted by the research team during data collection; 2. a peer review of the reported approach and implementation to data modelling; 3. an audit of the research team’s implementation tool that wei...

To date, only a handful of studies have attempted to investigate changes in the interactions between Information and Communications Technology (ICT) and travel behaviour over time, due to the lack of suitable datasets as well as the rapidly evolving characteristics of the ICT sector. This shortcoming is addressed in this paper by developing a metho...

The rapid development of information and communication technologies (ICT) has been argued to affect time use patterns in a variety of ways, with consequent impacts on travel behaviour. While there exists a significant body of empirical studies documenting these effects, theoretical developments have lagged this empirical work and in particular, mic...

Estimation of the value of travel time savings (VTTS) in the context of business travel has frequently relied on the assumption that travel time is in principle wasted and thus any reduction in travel time ought to be valued at the cost of a unit of labour and fully accrued to the employer. A more flexible approach was introduced by David Hensher i...

Travel time has traditionally been perceived as a negative consequence of spatial separation of activities. Based on this paradigm, transport policy-making has remained largely oriented towards minimising travel duration. However, this approach has recently been called into question in light of emerging evidence that travel time can be spent produc...

Majority of the studies concerning the interactions between Information and Communication Technologies (ICT) and thave so far focused on determining the net effect of ICT use on travel demand (substitution and complementarity). More recent studies have started investigating modifications in travel arising from growing ICT use, including facilitatio...

In the light of recent and on-going developments in information and communication technologies (ICT), there is an ever growing interest in the relationship between digital behaviour and physical mobility. However, data shortages together with privacy and ethical concerns can limit comprehensiveness of the empirical studies dealing with the issue. D...

The presentation, prepared for the special session on the value of travel time savings (VTTS) has been aimed at drawing attention to the relationship between the value of time (VOT) and value of travel time savings using with the aid of estimation of suitable time allocation framework. Following that, and in a bit less orthodox way, the point has b...

The dynamic development of Information and Communication Technologies (ICT) in recent decades has been one of the most important drivers of people’s increasing participation in activities based in digital reality. As a result, it has been argued that the importance of travel as a means of linking physically-distant activities might diminish. In fac...

The valuation of travel time savings plays a fundamental role on transport modelling and appraisal. The theoretical foundation for placing a value on travel time savings rests on models of time allocation. In particular, we argue that all existing models share a critical weakness in that they assume that a given quantum of time can be used for one...

Recent developments in information and communication technologies (ICT) have created a wide range of new capabilities for individuals to interact with one another and participate in activities. These developments are affecting both the ways in which conventional activities are performed (e.g., the growth of tele-working and e-shopping) and leading...

Each day individuals undertake a number of various activities. In doing so, they decide on what to do when, where, for how long and in what order. As a result, apparently simple choices such as time of shopping or what to do on the train, as well as more difficult ones regarding hours of work or commuting mode, create a complex system of interrelat...
