international travel has become increasingly common and accessible, hence, about two billion passengers undertake international and domestic air travel each year. venous thromboembolism (vte) is a serious public health disorder which may occur following prolonged travel, especially after air travel. a direct relation between vte development and prolonged travels has been documented, while some ...

OBJECTIVE Countries and regions vary substantially in transport related physical activity that people gain from walking and cycling and in how this varies by age and gender. This study aims to quantify the population health impacts of differences between four settings. METHOD The Integrated Transport and Health Model (ITHIM) was used to estimate health impacts from changes to physical activit...

The growing number of bike sharing systems (BSS) in many cities largely facilitates biking for transportation and recreation. Most recent bike sharing systems produce time and location specific data, which enables the study of travel behavior and mobility of each individual. However, despite a rapid growth of interest, studies on massive bike sharing data and the underneath travel pattern are s...

This paper, focused primarily on UK data and debates, considers the potential significance of travel time use within past, present and future patterns of mobility. In transport scheme appraisal, savings in travel time typically represent a substantial proportion of the benefits of a scheme – benefits used to justify its often enormous financial costs. Such benefits are founded on the assumption...

One of the basic assumptions of the travel cost method for recreational demand analysis is that the travel cost is always incurred for a single purpose recreational trip. Several studies have skirted around the issue with simplifying assumptions and dropping observations considered as nonconventional holiday-makers or as nontraditional visitors from the sample. The effect of such simplification...

Over the last decade, several authors have questioned the validity of the hedonic travel cost model, arguing instead that the random utility model is a superior method for valuing recreational site attributes. This paper demonstrates that the two methods emanate from a similar utility theoretic framework; yet in practice these methods differ in the assumptions made in their application. Constra...

Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...

This paper investigates the interactions between the coping travel behaviour of the disadvantaged and policies for a sustainable transport system in Hong Kong. The concepts of quality of life, a sustainable transport system and coping behaviour are reviewed. The construction of an effective sustainable transport system depends on transport policy makers understanding individual travel behaviour...

This paper considers how changes in the fabric of society and its values, a subject usually considered to be outside the conventional scope of the transport profession, can have a profound impact on travel demand. The paper stems from the Transport Visions Network, a unique activity involving young professionals from academia, consultancy and government. It raises awareness of the diversity of ...
