Real time data from several traffic participants such as smart-phone users and vehicles equipped with GPS devices (taxi and bus fleets) is potentially available in the form of a continuous data stream in several mega cities. This real time data can be augmented with that from the traditional sensors for the implementation of several advanced traffic management and control strategies. In this re...

It is traditional for people living in towns and cities to stroll through the public parks and feed the ducks and geese. It is widely believed that such activities are productive in that they offer nutrition to waterfowl, present entertainment for the family, and in today’s urbanizing society, provide an opportunity for people to interface with nature. However, supplemental feeding of wild wate...

Those who have been charmed by the ambience of life in an Asian city probably felt its evocative and at times palpable connection with past traditions and history and enjoyed the sociability of its street life. They might wonder how one could sustain and even replicate the sense of place and the quality of life one experiences in such a city. The Disappearing Asian City shows that such cities f...

Based on the traditional trip attraction model, a new method of operation condition evaluation and supply scale forecasting for public parking facilities is proposed. It begins with the operation condition investigation of existing parking facilities, and then analyzes qualitatively the existing parking facilities supply scale by four indexes. Finally, it can calculate the supply scale in predi...

In this paper, we use neural networks in order to model the seasonal component of the residual variance of a mean-reverting Ornstein-Uhlenbeck temperature process, with seasonality in the level and volatility. We also use wavelet analysis to identify the seasonality component in the temperature process as well as in the volatility of the temperature anomalies. Our model is validated on more tha...

“Urban Pixels” are wireless, solar-powered lighting units for cities that blur the boundary between digital display technology and traditional urban lighting. By combining a renewable energy source with RF communication it is possible to achieve a self-sustaining, distributed display network that can be attached to any building surface and reconfigured with ease. Depending on their configuratio...

BACKGROUND Driving a taxicab remains one of the most dangerous occupations in the United States, with leading homicide rates. Although safety equipment designed to reduce robberies exists, it is not clear what effect it has on reducing taxicab driver homicides. FINDINGS Taxicab driver homicide crime reports for 1996 through 2010 were collected from 20 of the largest cities (>200,000) in the U...

India is the second largest country in the category of population. With the increasing population the consumption of the vehicles also increases, leading to critical burden on traffic management in the metropolitan cities and towns of the country. In 2011-12 alone, 20.4 million motorized vehicles were sold in India leading to congestion and accidents on the roads. For controlling the traffic on...

The dynamics behind human migrations are very complex. Economists have intensely studied them because of their importance for the global economy. However, tracking migration is costly, and available data tends to be outdated. Online data can be used to extract proxies for migration flows, and these proxies would not be meant to replicate traditional measurements but are meant to complement them...
