The emergence and growth of global city-regions (GCRs) or mega-city region (MCRs) around the world has become an important phenomenon. In China's Pearl River Delta, the area in the very South-East which incorporates Hong Kong and Guangzhou has seen 30 years of extremely rapid economic growth and urbanization, turning the many agglomerations into one super-large urbanized zone, a real MCR. Bit the...
The concept of the sustainable development is brought forward in the 1980s and has been received and paid close attention in the world. Under the new situation, highway transport is considered as an important transport, so it is worthwhile to how to play the role and provide strong guarantee for socio-economic development and achieve the own sustainable development. From the point of sustainable development,...
This paper discusses how remote sensing, specifically Light Detection and Ranging (LiDAR), was used to carry out a detailed Low Impact Development (LID) suitability estimate in an urban watershed. The research uses LiDAR as an accurate and efficient tool for identifying and quantifying LID retrofit locations. The results of the LiDAR analysis were run in a hydrologic model to determine the flood response...
Cities will have to change their policies because of climate change & increased pollution. Climate change forces cities to go for climate mitigation, or adaptation activities. Many cities claim to be ecological cities, but there are no non-ambiguous definitions of ecological cities. In this paper it is suggested to make an inventory of criteria for defining ecological cities and to make an effort...
Today, the uncontrolled urban growth in Istanbul has been far from addressing the issues of equity, social justice, employment, poverty and healthy urban environment. As acknowledged by an emerging body of literature, coping with the problems of unplanned and unsustainable urbanisation requires a thorough change in the way decision-making of central and local governments. Nevertheless, the new urban...
Asset management has conquered a prominent position in infrastructure operation and maintenance over the past few years. In this paper, we will describe the way asset management has been applied in the organization of ProRail, the Dutch railway infrastructure manager. The paper shows that asset management has strongly improved the efficiency, both in terms of financial management and capacity, of...
Policies and economics in social networks are intertwined with a physical system. Research on socio-technical systems, including eco-cities, energy systems, transport infrastructures and supply chains, tries to combine the technical engineering discipline for the physical system with the social perspective on consumer behaviour. However, efforts to develop an ontology, i.e. a shared formal conceptualisation,...
Energy savings are required, and behavioural change is a good guarantee for this. This paper presents an interdisciplinary four-step approach towards such energy savings. It is based on two types of monetary instruments (white certificates and complementary currencies), that make use of the smart meter infrastructure as a measurement platform for assessing the realised energy savings. A social component...
Ports are a vital part of the maritime transportation system. The urgent need for redevelopment of older ports and investments in port expansions, and the dilemma of a long payback time etched with uncertainty calls for new strategies. Flexibilities in a (real) system, that enable it to change according to the future that unfolds, are known as real options. An evaluation technique, commonly known...
Infrastructure systems are crucial to the functioning of society. Their long-term planning is therefore of great importance. Uncertainty about the future conditions under which an infrastructure system will function is of particular importance for successful long-term planning. The uncertainties about the future encountered in the long term planning of infrastructure systems is increasing due to developments...
In the present study, we propose a concept of Infrastructure Key Node which is constructed as the most significant connector in the infrastructure network and as the point where the complexity of infrastructure system emerges. We also present the properties and features of the key node and an outlook of apposite studies. It is posited that infrastructure key node is the essential cause to the emergence...
The eco-city concept may in practice too easily turn out into a “green finish” to traditional planning, design and construction practice. How can we ensure that eco-city goals are truly achieved? Do we need traditional governmental tools and requirements such as regulation and enforcement, or would non-regulatory instruments achieve better results? What are examples of both categories? And, last but...
This is an empirical paper that measures and interprets changes in intercity relations at the global scale in the period 2000-2008. We draw on the network model devised by the Globalization and World Cities (GaWC) research group to measure global connectivities for 132 cities across the world in 2000 and 2008. A range of statistical techniques is used to explore changing connectivities at the city...
Problems related to public policy, organizational strategy, and organizational change in infrastructure management can be seen as complex multi-actor problems. Actor analysis methods are therefore receiving more and more attention. However, no general definition and categorization exists to date. In this paper we present a categorization of actor analysis methods.
Spatial planning is complex in which many stakeholders, each with their own interests are involved. In urban areas, many different aspects play a role, such as mobility, noise, air quality, safety and esthetics. Human health and comfort as well as climate change are topics that arise. With existing models, it is difficult to produce results of calculations on time and to produce calculations on different...
The introduction of market forces in the energy sector has drastically changed the climate for investments in the electricity infrastructure. In contrast with the former public monopoly situation, many new uncertainties need to be taken into account in network investment decisions. Another marked difference is the fragmentation of energy markets and the entrance of new players on the energy market...
In response to increasing environmental problems and consciousness in relation to urbanization, more and more cities are trying to become eco-cities. We can question, however, whether these cities can be considered as sustainable cities. The eco-city concept usually includes criteria regarding energy and water consumption, transport, waste management, amount of green spaces, etc. However, food consumed...
