Road Safety Audit
A road safety audit (RSA) is defined as "the formal safety performance examination of an existing or future road or intersection by an independent, multidisciplinary team. It qualitatively estimates and reports on potential road safety issues and identifies opportunities for improvements in safety for all road users." Road safety audits differ from conventional traffic safety studies in two key ways: road safety audits are often pro-active investigations, rather than reactive investigations of sites with histories of complaints or poor safety performance, and the investigation team is independent from the staff that is designing the project or maintains the road. Road safety audits are commonly used in the United Kingdom and Australia, and are coming into wider use in the United States. They are a mandatory requirement for all trunk road Highway Improvement Schemes in the UK (including motorways). The requirements of a Road Safety Audit are contained in the Design Manual for Roads ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. It also forms the basis of the road design standards used in many other countries. DMRB volumes form part of a suite of technical documents produced by National Highways, which comprises: * Design Manual for Roads and Bridges (DMRB) * Manual of Contract Documents for Highway Works (MCHW) * Asset Maintenance and Operation Requirements (AMOR) which supersedes the Network Maintenance Manual and Routine and Winter Service Codes, and its predecessor the Trunk Road Maintenance Manual Overview The volumes within the Design Manual for Roads and Bridges are: Volume 0 – Introduction and General requirements Volume 1 – Highway Structures: Approval Procedures and General Design Volume 2 – ...

New York State Department Of Transportation
The New York State Department of Transportation (NYSDOT) is the department of the New York state government responsible for the development and operation of highways, railroads, mass transit systems, ports, waterways and aviation facilities in the U.S. state of New York. This transportation network includes: * A state and local highway system, encompassing over 110,000 miles (177,000 km) of highway and 17,000 bridges. * A 5,000 mile (8,000 km) rail network, carrying over 42 million short tons (38 million metric tons) of equipment, raw materials, manufactured goods and produce each year. * Over 130 public transit operators, serving over 5.2 million passengers each day. * Twelve major public and private ports, handling more than 110 million short tons (100 million metric tons) of freight annually. * 456 public and private aviation facilities, through which more than 31 million people travel each year. It owns two airports, Stewart International Airport near Newburgh, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regression Toward The Mean
In statistics, regression toward the mean (also called reversion to the mean, and reversion to mediocrity) is the fact that if one sample of a random variable is extreme, the next sampling of the same random variable is likely to be closer to its mean. Furthermore, when many random variables are sampled and the most extreme results are intentionally picked out, it refers to the fact that (in many cases) a second sampling of these picked-out variables will result in "less extreme" results, closer to the initial mean of all of the variables. Mathematically, the strength of this "regression" effect is dependent on whether or not all of the random variables are drawn from the same distribution, or if there are genuine differences in the underlying distributions for each random variable. In the first case, the "regression" effect is statistically likely to occur, but in the second case, it may occur less strongly or not at all. Regression toward the mean is thus a useful concept to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austroads
Austroads is the apex organisation of road transport and traffic agencies in Australia and New Zealand. It publishes guidelines, codes of practice and research reports that promote best practice for road management organisations in Australasia. Austroads is based in Sydney and funded by the Federal Government. Operations of Austroads are primarily administrative, with all research and engineering work contracted out, such as to produce the Australian standards for construction, planning and design in roads. Austroads membership comprises: * Transport for NSW New South Wales * VicRoads * Department of Transport & Main Roads, QueenslandAustroads publications |
Road-traffic Safety
Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, Driving, motorists, vehicle passengers, horse riders, and passengers of on-road public transport (mainly buses and trams). Best practices in modern road safety strategy: As sustainable solutions for classes of road safety have not been identified, particularly low-traffic rural and remote roads, a hierarchy of control should be applied, similar to classifications used to improve occupational safety and health. At the highest level is sustainable prevention of serious injury and death crashes, with sustainable requiring all key result areas to be considered. At the second level is real-time risk reduction, which involves providing users at severe risk with a specific warning to enable them to take mitigating action. The third level is about reducing the crash risk which involves applying the road-design st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verification And Validation
Verification and validation (also abbreviated as V&V) are independent procedures that are used together for checking that a product, service, or system meets requirements and specifications and that it fulfills its intended purpose. These are critical components of a quality management system such as ISO 9000. The words "verification" and "validation" are sometimes preceded with "independent", indicating that the verification and validation is to be performed by a disinterested third party. "Independent verification and validation" can be abbreviated as "IV&V". In practice, as quality management terms, the definitions of verification and validation can be inconsistent. Sometimes they are even used interchangeably. However, the PMBOK guide, a standard adopted by the Institute of Electrical and Electronics Engineers (IEEE), defines them as follows in its 4th edition: * "Validation. The assurance that a product, service, or system meets the needs of the customer and other iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
