This paper investigates the cost of travel time variability for car users at the peak hour. In particular, we derive the marginal social cost of travel time variability, which takes the feedback of travel time unreliability on the congestion profile into account. This is in contrast with the value of travel time variability, which treats congestion as an exogenous phenomenon. Congestion is mode...

INTRODUCTION Singapore has a fast-growing travel industry, but few studies have been done on travel characteristics and travel health practices. This study describes the profile and healthseeking behaviour of travellers attending a travel health clinic in Singapore. MATERIALS AND METHODS A cross-sectional survey was conducted on travellers attending the Traveller's Health and Vaccination Cent...

We exploit a unique merchant-level dataset from the monopoly payment card network in China to study payment card pricing. We develop hypotheses associating payment card pricing to card penetration rate, profitability and fraud risk. Our empirical analysis uses the variations in those three factors across industries to show that the card network charges a higher merchant discount for industries ...

A substantial literature examines the social and environmental correlates of walking to school but less addresses walking outside the school commute. Using travel diary data from London, we examined social and environmental correlates of walking: to school; outside the school commute during term time; and during the summer and weekends. Living in a household without a car was associated with al...

Nowadays air travel is one of the most popular traveling as its advantages. A disabled should commute easily, so Facilitation of air traveling is vital. A disabled needs various services which depends on travel steps. These needs should have supported by travel agencies and airport staffs. Therefore, planners must be considering not only physical environment but also well services. This paper i...

We study route choice behavior when travel time is uncertain. In this case, users do not minimize expected travel time but also take into account travel time variability. We collected survey data and analyze them with a method based on the ordered probit model. This allows us to have an ordinal as well as cardinal measures of risk aversion. Such an approach is therefore consistent with expected...

After an interesting battle against both the University travel agents and what appeared to be the entire staff of the finance department (see Sharee’s recent memo on procedures for organising staff travel), funding for this travel got through to my bank account after the conference, not before it. Nevertheless, after about 15 hours of traveling, I made it to Bangkok at about midnight local time...

Travel journals from different historical periods contain valuable insights that could be analyzed from different aspects and through that we can understand other people’s points of view about us. Description of different cities in travel literature represents French travelers’ views about these cities besides informing us about the quality and quantity of those cities at the times. “Represen...

Modelling access to services, using cost path analysis and distance decay models, can be improved if travel time rather than just distance is taken into account. If just straight line distance is used then traffic congestion in urban areas and rough bendy rural roads are not considered in the analysis and the results are subsequently distorted. An accurate road network layer that shows travel s...

Introduction: The number of foreign travelers arriving in India has shown an exponential increase from 1.2 million in 1981 to 8.03 million in the year 2015, with an annual growth rate of 4.5%. With the influx of internationally mobile students to developing countries such as India comes the responsibility of having to cater to the health needs of these visitors. The current stu...
