Aerosol optical depth (AOD) is the key parameter for determining aerosol radiative effects and air quality variation. It important to quantify nighttime aerosols using satellite-based night light images understand their diurnal variations. This study selected high-resolution low from Glimmer Imager (GLI) aboard SDGSAT-1 satellite examine spatial–temporal changes in emitted urban surface of Beij...

As Shanghai is a megacity and pioneer in smart city development China, this paper used as example to investigate over the past ten years. By collecting data from multiple sources, case study methodology was utilized explore Shanghai’s practice. Based on key events phases of development, practical contents were systematically investigated. The main conclusions research included four aspects, con...

This paper evaluates two infrastructure mega-projects connected to the 2010 Winter Olympics in Vancouver’s downtown peninsula: renovation of BC Place Stadium and Vancouver Convention Centre expansion. These projects correspond categories often constructed alongside sporting mega-events with intended tourism development legacies that have a history financial underperformance. Touching upon liter...

Over the last 50 years, the world has faced dramatic growth of its urban population. In 2007 the amount of urban residents has outnumbered the rural population for the first time in history and by the year 2030 already two-thirds of the world’s population is expected to live in cities [1]. The number of so-called mega cities –cities with more than 10 million inhabitants– increased in the period...

Public urban mobility systems are composed by several transportation modes connected together. Most studies in urban mobility and planning often ignore the multi-layer nature of transportation systems considering only aggregated versions of this complex scenario. In this work we present a model for the representation of the transportation system of an entire city as a multiplex network. Using t...

Peak electricity demands from huge number of households in a mega-city would cause contention, leading to potential blackout. This paper proposes bi-directional collaboration via a Smart Energy Monitor System (SEMS) between consumers and energy suppliers, exchanging real-time energy usage data with smart meters over the Internet and mobile devices for well-informed decisions and even prediction...

Large reduction in emissions of anthropogenic pollutants in a mega city during the week-long holiday gives an opportunity to investigate how the urban air quality reacts to reductions in emission. This study conducted a systematical examination of the “Spring Festival effect” over three consecutive winters in Shenzhen with a population of greater than ten million, and the difference in the conc...
