Understanding the drivers of energy and material flows of cities is important for addressing global environmental challenges. Accessing, sharing, and managing energy and material resources is particularly critical for megacities, which face enormous social stresses because of their sheer size and complexity. Here we quantify the energy and material flows through the world's 27 megacities with p...
For the past few years, phenomena such as traffic congestion and traffic accidents in big cities have occurred one after another, greatly and adversely affecting the people’s lives. Intelligent transportation system is perceived as an optimum solution to solve this question. This paper delves into several common route guidance algorithms, analyzes respective characteristics, improves and parall...
Cities are dependent on their hinterlands for their function and survival. They provide resources such as people, materials, water, food and energy, as well as areas for waste disposal. Over the last 50 years, commerce and trade has become increasingly global with resources sourced from further afield often due to cheap labour costs, better transportation and a plentiful supply of energy and ra...
Smart cities and digital democracy have begun to converge around mobile computing, enabling, web services, and different operational and shared databases to create new opportunities for civic engagement for concerned citizens as well as new efficiencies for public services provided by local government. While many of these projects remain siloed to specific departments of local government, when ...
emobility challenges of the developingworld are considerably different than those inwealthier, advanced countries, and so are the challenges of coordinating transportation and land use. Rapid population growth, poverty and income disparities, overcrowded urban cores, poorly designed road networks, spatial mismatches between housing and jobs, deteriorating environmental conditions, and economic...
The rapid growth experienced by many cities has created huge pressures on their traffic and transport systems. One common solution consists of increasing the number of roads available, but is not always the most appropriate. The application of Information and Communications Technologies enabling more efficient and effective use of the existing transport infrastructure is necessary (also known a...
Increasing pressures caused by negative consequences of transportation and traffic problems in major cities, have resulted many attempts towards improvement of planning and management of transportation systems, according to sustainability objectives. In this paper, a comprehensive model is developed using a system dynamics approach to evaluate sustainable urban transportation. This model includ...
It is important to understand the settlement morphology and its transition process in the rapid urbanization cities of developing countries. It is equally important to learn about the relationships between transport energy consumption and the transition of settlement morphology and its underlying processes. Finally, if the existing transportation technologies are already adequately meeting the ...
With the emergence of the response to climate change as a global agenda, UNFCCC member countries must report their Greenhouse Gas (GHG) emissions and absorptions. With conventional carbon emission estimation methods such as the IPCC Guideline, however, it is impossible to measure reduction of carbon emissions by U-City services. Therefore, this study proposed estimating carbon emission reductio...
