An understanding of urban development processes is crucial in urban development planning and sustainable growth management. The urban development process involves many actors and types of behaviour and various policies, resulting in spatial and temporal complexity. The nonlinear dynamics inherent in these growth processes opens up the possibility(More)
BACKGROUND The inequities in healthcare services between regions, urban and rural, age groups and diverse income groups have been growing rapidly in China. Equal access to basic medical and healthcare services has been recognized as "a basic right of the people" by Chinese government. Spatial accessibility to healthcare facilities has received huge(More)
China has achieved rapid urbanization and unprecedented economic booming over the past three decades. Numerous cities and towns dreamed of cloning the miracles of Shenzhen and Pudong, Shanghai, in terms of their international development. However, inappropriate development strategies have meant that the majority of fast expanding urban suburbs or newly(More)
Involving stakeholders in decision-making at planning workshops requires a computer system to respond quickly to various scenarios proposed by participants. Due to the increasing complexity of urban systems, such planning support often faces the challenges of "big data" and poor computational performance. This paper proposes a new approach using parallel(More)
A city is a complex system with complicated interactions between transport, land use, environment, population at a variety of scales. Understanding these interactions is the prerequisite for predicting urban changes, supporting sustainable urban development planning. In this paper, we divide the evolution of urban data into four stages. Then the(More)
Modeling thermal comfort provides quantitative evidence and parameters for effective and efficient urban planning, design, and building construction particularly in a dense and narrow inner city, which has become one of many concerns for sustainable urban development. This paper aims to develop geometric and mathematical models of wind and thermal comfort(More)
