BACKGROUND Travel time is an important metric of geographic access to health care. We compared strategies of estimating travel times when only subject ZIP code data were available. RESULTS Using simulated data from New Hampshire and Arizona, we estimated travel times to nearest cancer centers by using: 1) geometric centroid of ZIP code polygons as origins, 2) population centroids as origin, 3...

Can urban design improve the environment? If communities could be designed to reduce automobile use, then yes. But can urban design influence travel? Surprisingly perhaps, the effects of any specific neighborhood feature on travel behavior at the margin are all but unknown. The policy significance of this issue is reflected in the swelling popularity of the “new urbanism” and other planning str...

Introduction: Travel health centers offer very important health services for individuals traveling abroad. Little is known about the health status and knowledge of travel health, travel-related diseases, and vaccinations of individuals who travel abroad and visit travel health centers. This research studied travelers who visited a travel health center in order to evaluate their...

Introduction: International travels have increased dramatically in recent years. Adolescents constitute a fast-growing group of travelers. Travels provide an opportunity for exposure to high-risk behavior. The current study reviewed the published data about travel-related morbidity among adolescents traveling to international destinations. Methods: PubMed...

The efficiency of traffic flows in urban areas is known to crucially depend on signal operation. Here, elements of signal control are discussed, based on the minimization of overall travel times or vehicle queues. Interestingly, we find different operation regimes, some of which involve a “slower-is-faster effect”, where a delayed switching reduces the average travel times. These operation regi...

The rapid development of multimodal transportation system prompts travellers to choose multiple transportation modes, such as private vehicles or taxi, transit (subways or buses), or park-and-ride combinations for urban trips. Traffic corridor is a major scenario that supports travellers to commute from suburban residential areas to central working areas. Studying their modal choice behaviour i...

The French National Institute for Statistics and Economic Studies (INSEE) qualifies as “urban unities” every town inside urban agglomerations. But in these urban organizations, centres, suburban and/or rural areas can exist and we suspect they require differentiated and/or specific transport services. Based on an economic approach, the distinction between urban and suburban or rural areas depen...

This paper presents a methodology to construct travel related activity schedules for individuals in a synthetic population. The resulting list of activity schedules are designed as an input into a micro-simulator for urban transport dynamics analysis. The methodology involves two main steps. The first step generates a synthetic population based on census data sourced from the Australian Bureau ...
