Abstract Introduction: Cardiovascular diseases are the first cause of death in the worldwide. Taxi drivers are a high risk group for developing cardiovascular disease, due to exposure to unhealthy working conditions. The aim of this study was to assess the prevalence of cardiovascular risk factors among taxi drivers. Methods: This cross-sectional study in 2016, was conducted on 110 taxi drive...

This research is motivated by problems in urban transportation and labor mobility, where the agent flow is dynamic, non-deterministic and on a large scale. In such domains, even though the individual agents do not have an identity of their own and do not explicitly impact other agents, they have implicit interactions with other agents. While there has been much research in handling such implici...

In the UK, licensing of taxi drivers is dealt with by local government authorities. In Scotland, before the recent reorganization of local government, taxi licensing was under the jurisdiction of District Councils, so a telephone survey was conducted of all 52 mainland Scottish District Councils to ascertain the procedures which were being employed in assessing medical fitness to drive a taxi, ...

Stringent federal and state programs along with technology innovation have resulted in declining emissions from static sources (e.g. power plants) and are projected to meet national quality standards by 2025. The same cannot be said for mobile sources of emissions from flight operations at airports. In the absence changes in airport operations, the forecast rates of growth in flight operations ...

A transit ridership study is an essential part of sustainability, and can provide a deep understanding of people’s travel patterns for efficient transportation development and urbanization. However, there is a lack of empirical studies comparing subway and taxi services, and their interactions within a city, that is to say, the interdependent transportation networks. Incorporating new data, thi...

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 ...

With the expected continued increases in air transportation, the mitigation of the consequent delays and environmental effects is becoming more and more important, requiring increasingly sophisticated approaches for airside airport operations. Improved on-stand time predictions (for improved resource allocation at the stands) and take-off time predictions (for improved airport-airspace coordina...

Grey matter volume increases have been associated with expertise in a range of domains. Much less is known, however, about the broader cognitive advantages or costs associated with skills and their concomitant neuroanatomy. In this study we investigated a group of highly skilled navigators, licensed London taxi drivers. We replicated findings from previous studies by showing taxi drivers had gr...
