Design Manual For Roads And Bridges
The Design Manual for Roads and Bridges (DMRB) is a series of 15 volumes that provide standards, advice notes and other documents relating to the design, assessment and operation of trunk roads, including motorways in the United Kingdom, and, with some amendments, the Republic of Ireland.

The A20 Dual Carriageway Becomes The M20 Motorway - Geograph
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun '' thee'') when followed b ...

Environmental Impact Assessment
Environmental Impact assessment (EIA) is the assessment of the environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action. In this context, the term "environmental impact assessment" is usually used when applied to actual projects by individuals or companies and the term " strategic environmental assessment" (SEA) applies to policies, plans and programmes most often proposed by organs of state. It is a tool of environmental management forming a part of project approval and decision-making. Environmental assessments may be governed by rules of administrative procedure regarding public participation and documentation of decision making, and may be subject to judicial review. The purpose of the assessment is to ensure that decision makers consider the environmental impacts when deciding whether or not to proceed with a project. The International Association for Impact Assessment (IAIA) defines an envir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Assessment
Policy Impact Assessments (IAs) are formal, evidence-based procedures that assess the economic, social, and environmental effects of public policy. They have been incorporated into policy making in the OECD countries and the European Commission. Key types of impact assessments include global assessments (global level), policy impact assessment (policy level), strategic environmental assessment (programme and plan level), and environmental impact assessment (project level). Impact assessments can focus on specific themes, such as social impact assessments and gender impact assessments. IAs can improve legislation by: * Informing policy makers about potential economic, social, and environmental ramifications * Improving transparency so that contributions to sustainability and "better regulation" are disclosed and special interest lobbying is discouraged * Increasing public participation in order to reflect a range of considerations, thereby improving the legitimacy of policies * Cla ...

Road Transport In Ireland
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which ...

Manual For Streets
In England and Wales, the ''Manual for Streets'', published in March 2007, provides guidance for practitioners involved in the planning, design, provision and approval of new streets, and modifications to existing ones. It aims to increase the quality of life through good design which creates more people-oriented streets. Although the detailed guidance in the document applies mainly to residential streets, the overall design principles apply to all streets within urban areas. A ''street'' is defined as "a highway with important public realm functions beyond the movement of motor traffic" – i.e. by its function rather than some arbitrary traffic flow limit. Overview The UK Department for Transport (DfT) and the Department for Communities and Local Government (DCLG), with support from the Commission for Architecture and the Built Environment (CABE), commissioned WSP Group, Transport Research Laboratory (TRL), Llewelyn Davies Yeang and Phil Jones Associates to develop ''Manua ...

Roads In The United Kingdom
The United Kingdom has a network of roads, of varied quality and capacity, totalling about . Road distances are shown in miles or yards and UK speed limits are indicated in miles per hour (mph) or by the use of the national speed limit (NSL) symbol. Some vehicle categories have various lower maximum limits enforced by speed limiters. A unified numbering system is in place for Great Britain, whilst in Northern Ireland, there is no available explanation for the allocation of road numbers. The earliest specifically engineered roads were built during the British Iron Age. The road network was expanded during the Roman occupation. Some of these roads still remain to this day. New roads were added in the Middle Ages and from the 17th century onwards. Whilst control has been transferred between local and central bodies, current management and development of the road network is shared between local authorities, the devolved administrations of Scotland, Wales and Northern Irela ...

National Roads Authority
The National Roads Authority (NRA) ( ga, An tÚdarás um Bóithre Náisiúnta) was a state body in Ireland, responsible for the national road network. The NRA was established as part of the Roads Act 1993 and commenced operations on 23 December 1993 in accordance with S.I. 407 of 1993. The NRA merged with the Railway Procurement Agency and was effectively dissolved on 1 August 2015. The merger of the two agencies is called Transport Infrastructure Ireland (TII). County councils remain responsible for local and regional roads, as well as various tasks like setting speed limits. The NRA, meanwhile, was responsible for the planning, maintenance and construction of National Primary Routes and National Secondary Routes as well as establishing safety measures. Ireland's national road network consists of of National Primary Routes and of National Secondary Routes. The body also plays an environmental and archaeological role as part of the road building programme, publishing an ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Approach To Appraisal
The New Approach to Appraisal (also NATA) was the name given to a multi-criteria decision framework used to appraise transport projects and proposals in the United Kingdom. NATA was built on the well established cost–benefit analysis and environmental impact assessment techniques (such as those contained in the Highways Agency's Design Manual for Roads and Bridges (DMRB)) for assessing transport projects and proposals. In April 2011 the Coalition Government decided that the term NATA would no longer be used. However, the principles and key elements of the NATA framework remain in the Department for Transport's Transport Analysis Guidance (TAG). History NATA was introduced by the then Department for Transport, Environment and the Regions as part of the 1998 Integrated Transport White Paper and first used in the 1998 review of trunk road schemes. Its development reflected the new Labour Government's aim of providing a more balanced approach to transport appraisals, in terms ...
