This article is a single source introduction to the emerging concept of smart cities. It can be used for familiarizing researchers to the vast scope of research possible in this application domain. The smart city is primarily a concept and there is still not a clear and consistent definition of among practitioners and academia. In a simplistic explanation, a smart city is a place where traditio...

As cities grow, they add jobs and services, becoming more complex economically as well as physically. The need for new jobs places huge demands on cities that are struggling to provide the public services that growth demands, often in the face of existing unemployment. In the developing world, many of the new jobs needed are for unskilled and relatively uneducated workers, both migrants and tho...

Traffic congestion has been increasing because of increased population growth mainly in major cities due to urbanization. Traffic congestion causes increased air pollution, travel time and mostly traffic accidents; therefore we need an efficient traffic management system. Today most of the cities of the world have intelligent transport system which is equipped with electronics devices to commun...

Background: By 2050, sub-Saharan Africa’s (SSA) urban population is expected to grow from 414 million to over 1.2 billion. This growth will likely increase challenges to municipalities attempting to provide access to water supply and sanitation (WS&S). This study aims to characterize trends in access to WS&S in SSA cities and identify factors affecting those trends. Methods: DHS data collected ...

The need to prepare cities for climate change adaptation requests the urban modeller community to implement sustainable adaptation strategies within their models to be tested against specific city morphologies and scenarios. Greening city roofs is part of these strategies. In this context, the GREENROOF module for TEB (town energy balance) has been developed to model the interactions between bu...

I dentifying critical issues confronting an urban sociology of the twenty-first century entails a decision and a judgment, both in turn inevitably derived from an interpretation of history in the making. The enterprise is, thus, partial and positioned. Developing analytical and empirical elements (and I emphasize elements) for an urban sociology focused on the early twenty-first century does no...

One of the important items of highway information has been, and probably will always be, who should pay how much of the cost of building and maintaining roads and streets. Of similar importance is the question where should we spend the money collected in taxes for highways. Each year the highway officials at every government level have more roads which need to be rebuilt or maintained than avai...
