The Internet is one of the major information sources for trip planning. However, sometimes it can be difficult to use, especially for planning a trip to a novel destination with a different culture. Using mixed methods which are comprised of process tracing, think aloud protocol, and clickstream analysis, this research explores the usability problems and barriers when American college students'...

Diabetes is a disease which occurs by lack of insulin production or its inappropriate function.  Patients with diabetes who take insulin suffer from high blood sugar and face unique challenges while travelling as their schedules for insulin dosage and blood sugar regulation change. Therefore they need to organize carefully how they have to travel, instruments they should take, the actions...

This paper analyzes a model of early morning traffic congestion, that is a special case of the model considered in Newell (1988). A fixed number of identical vehicles travel along a single-lane road of constant width from a common origin to a common destination, with LWR flow congestion and Greenshields’ Relation. Vehicles have a common work start time, late arrivals are not permitted, and trip...

We herein present the case of a 15-month-old with visceral leishmaniasis diagnosed in the UK following a short trip to a popular holiday destination in Spain. Four months after the initial symptoms, the diagnosis was made incidentally on microscopy of a bone marrow biopsy taken for suspected haematological malignancy after the child developed hepatosplenomegaly, pancytopaenia, and Klebsiella pn...

Most location-aware mobile applications only make use of the user’s current location, but there is an opportunity for them to infer the user’s future locations. We present Trajectory-Aware Search (TAS), a mobile local search application that predicts the user’s destination in real-time based on location data from the current trip and shows search results near the predicted location. TAS demonst...

Transit trip planners are now found on most transit authority websites. This feature gives transit users a full itinerary from a point of origin to a destination. The web server on which the trip planner is installed usually stores usage logs on a daily basis. Log files contain data on origins, destinations, calculated paths, and other website entries. The main purpose of this article is to det...

In this work, we investigate the potential benefits of introducing relay stations in the round-trip ridesharing problem. In the classical round-trip ridesharing system, the pick-up and drop-off locations for the rider don’t differ from his origin and destination, respectively, for both outgoing and return trips. This system is straightforward but inflexible and unbalanced as it puts the whole d...

Taxi trajectories reflect human mobility over a road network. Pick-up and drop-off locations in different time periods represent origins and destinations of trips, respectively, demonstrating the spatiotemporal characteristics of human behavior. Each trip can be viewed as a displacement in the random walk model, and the distribution of extracted trips shows a distance decay effect. To identify ...
