Cities in developing countries like India are facing some of the same concerns that North American cities are: congestion and urban growth. However, the concern in cities like New Delhi, India is that this growth is far more rapid as both urbanization and motorization are ongoing processes that have not yet peaked. Furthermore air quality in major Indian cities is now becoming a major concern w...

Current road-traffic optimisation practice around the world is a combination of hand tuned policies with a small degree of automatic adaption. Even state-ofthe-art research controllers need good models of the road traffic, which cannot be obtained directly from existing sensors. We use a policy-gradient reinforcement learning approach to directly optimise the traffic signals, mapping currently ...

Received Jan 9, 2018 Revised Mar 2, 2018 Accepted Mar 18, 2018 Because of rising dependency on fossil fuels, and rising amounts of toxic gases in the environment, it found that people are in need of a way to ensure the safety specifically those that live in cities. An approach is suggested in this paper, that is economical yet affords good detection, and can give accurate readings that can be a...

lose to 4 billion people live in cities. As the driver of environmental challenges, accounting for nearly 70% of the world’s carbon emissions, and as sites of critical social disparities, with 863 million dwellers now living in slums, urban settlements are at the heart of global change. This momentum is unlikely to disappear, as approximately 70 million more people will move to cities by the en...

The concept of ‘creative cities’ is gaining increased prominence amongst urban planners and policymakers concerned with the linkages between economic development and the ‘soft’ attributes of cities. While definitions of what exactly constitutes ‘creative industries’ and who the members of a ‘creative class’ actually are continue to be contested, many key urban policy actors are focused on engen...

Nations, in short, need an Urban Agenda themselves, given the economy-environment and people shaping power of cities. The New Deal is a national project for our time. We know our nation's future depends on enlightened urban statecraft.

“The process of formulating and implementing land policies is not only politically and technically difficult, it can also be costly. However, the costs of not formulating and implementing them are much higher” (Dowall, David & Clark Giles, 1997). Cities do not develop according to planners’ wishes – to the contrary, in the present and past, cities have always shown their own dynamic of developm...

rapid urbanization has brought environmentally, socially, and economically great challenges to cities and societies. to build a sustainable city, these challenges need to be faced efficiently and successfully. this paper focuses on the environmental issues and investigates the ecological approaches for planning sustainable cities through a comprehensive review of the relevant literature. the re...

With the rapid rate of urbanisation in developing countries across Asia and Africa, about 70% of the world’s population is expected to be living in cities by 2050. In their density and complexity, cities often drive national economies, provide a rich array of specialised services, ideas and innovation, with diverse social and cultural populations. However, with an estimated one billion people l...

Germany's big cities are gaining in attractiveness both as a place for living and as a location for companies. Even as Germany's total population is declining, the population of cities increased by nearly 3 percent between 1999 and 2008. The same is true for spatial shifts in the economy: During the past 10 years employment in big cities increased by nearly 4 percent while stagnating in Germany...
