Transportation systems are currently being transformed by advances in information and communication technologies. The development of autonomous transportation holds the promise of providing revolutionary improvements in speed, efficiency, safety and reliability along with concomitant benefits for society and economy. It is anticipated these changes will soon affect household activity patterns, ...

OBJECTIVE Dependence on motorized forms of transportation may contribute to the worldwide obesity epidemic. Shifts in transportation patterns occurring in China provide an ideal opportunity to study the association between vehicle ownership and obesity. Our objective was to determine whether motorized forms of transportation promote obesity. RESEARCH METHODS AND PROCEDURES A multistage random...

Transportation planning models are typically used to estimate future traffic patterns, peak period traffic, travel time, and various environmental or other related traffic flow characteristics. Unfortunately, traffic safety is seldom, if ever, explicitly considered proactively during the transportation planning process. This omission is attributed to various factors, including the lack of avail...

OBJECTIVE Although previous research has shown limited availability of healthy food in low-income urban neighbourhoods, the association between food source use and food-purchasing patterns has not yet been examined. We explored food-purchasing patterns in the context of food source use and food source access factors in low-income areas of Baltimore City. DESIGN Cross-sectional survey. SETTI...

Transportation networks play a crucial role in human mobility, the exchange of goods and the spread of invasive species. With 90 per cent of world trade carried by sea, the global network of merchant ships provides one of the most important modes of transportation. Here, we use information about the itineraries of 16 363 cargo ships during the year 2007 to construct a network of links between p...

To retire from work has potential consequences for patterns of everyday mobility in numerous ways. People born during the 1940s and are now retiring are more heterogeneous than earlier cohorts of retirees. They experience more years with good health after retirement, engage more in leisure-time activities and make more trips and errands. Therefore, their transportation behavior and mobility pat...

Many urban settlements result from a spatially distributed, decentralized building process. Here we analyze the topological patterns of organization of a large collection of such settlements using the approach of complex networks. The global efficiency (based on the inverse of shortest-path lengths), robustness to disconnections and cost (in terms of length) of these graphs is studied and their...

Massive amount of movement data, such as daily trips made by millions of passengers in a city, are widely available nowadays. They are a highly valuable means not only for unveiling human mobility patterns, but also for assisting transportation planning, in particular for metropolises around the world. In this paper, we focus on a novel aspect of visualizing and analyzing massive movement data,...

Mining interaction patterns may lead to important observations in a variety of domains such as ecology, biology, epidemiology, earth science and transportation. For example, in biology, it is well known that Nile crocodiles are often seen together with Egyptian plovers, showing a pattern of colocation. Conversely, there is usually competition between the same kind of species which yields patter...

With the fast development of positioning technology, spatiotemporal data has become widely available nowadays. Mining patterns from spatiotemporal data has many important applications in human mobility understanding, smart transportation, urban planning and ecological studies. In this chapter, we provide an overview of spatiotemporal data mining methods. We classify the patterns into three cate...
