Ruralisation of Urban Areas: Reversing Development Ruralisation of Urban Areas:
As with the three other longest and heaviest floating bridges on the planet, the colorfully named SR Bridge makes its home in the Seattle area. More News Summary Good design and advanced materials can improve transportation and energy, water, and waste systems, and also create more sustainable urban environments.
Inthe American Society of Civil Engineers issued a report card, grading various categories of U. Infrastructure is the combination of fundamental systems that support a community, region, or country.
It includes everything from water and sewer systems to road and rail networks to the national power and natural gas grids. Perhaps there will be a hydrogen grid in the future as well.
What is the current state of our infrastructure?
Engineers of the 21st century face the formidable challenge of modernizing the fundamental structures that support civilization. And urban infrastructure is not just a U. In many parts of the world, basic infrastructure needs are still problematic, and engineers will be challenged to economically provide such services more broadly.
What is involved in maintaining infrastructure? Of course, maintaining infrastructure is not a new problem. For thousands of years, engineers have had to design systems for providing clean water and disposing of sewage. In recent centuries, systems for transmitting information and providing energy have expanded and complicated the infrastructure network, beginning with telegraph and telephone lines and now encompassing all sorts of telecommunications systems.
Cable TV, cell phones, and Internet access all depend on elaborate infrastructure installations. Development of remote wind and solar energy resources will add more. Much of the existing infrastructure is buried, posing several problems for maintaining and upgrading it.
For one thing, in many cases, records of the locations of all the underground pipes and cables are unavailable or incomplete.
One major challenge will be to devise methods for mapping and labeling buried infrastructure, both to assist in improving it and to help avoid damaging it. A project of this sort is now underway in the United Kingdom, with the aim of developing ways to locate buried pipes using electromagnetic signals from above the ground.
The idea is to find metallic structures capable of reflecting electromagnetic waves through soil, much as a reflector makes a bicycle easier to see at night. How can you improve transportation systems? Other major infrastructure issues involve transportation.
Streets and highways will remain critical transportation conduits, so their maintenance and improvement will remain an important challenge. But the greater challenge will be engineering integrated transportation systems, making individual vehicle travel, mass transit, bicycling, and walking all as easy and efficient as possible.
An increasingly important question is the need to provide better access to transportation for the elderly and disabled. Cities around the world have begun developing integrated approaches, by establishing transportation hubs, for instance, where various transportation elements — rail, bus, taxi, walking and bicycle paths, parking lots — all conveniently meet.
In Hong Kong, several transportation services are linked in a system that allows a single smart card to be used to pay for all the services, including gas and parking. It would be best to introduce such systems in new development areas e.
While such services can help support growing urban populations, they must be accompanied by affordable and pleasant places for people to live. Engineers must be engaged in the architectural issues involved in providing environmentally friendly, energy-efficient buildings both for housing and for business.2 Degree of ruralisation in the Romanian Carpathians () Urban settlements 73 Rural settlements Data source: Population and Accommodation Census .

Sep 27, · This has been underpinned by the rapid growth in the world economy and in the proportion of gross world product and of the economically active population working in industry and services (since most industrial and service enterprises are in urban areas).

urban revitalization areas) and new cities, which will spring up over the next few decades in . The Department of Housing and Urban Development (HUD) is a U.S. government agency created in to support community development and homeownership.
