Quantm
Quantm is a software package, marketed as Trimble Quantm, that is used to design road alignments and railway alignments. The program performs an otherwise tedious and laborious task where an immense amount of data are involved and choices have to be made between a considerable number of options. The Quantm software takes the data and constraints into account and generates a prioritised list of optimised alignments that the user can choose between. Quantm was originally developed by the Australian research organisation CSIRO. The software was bought in 2006 by Trimble Navigation (now Trimble, Inc.) and further developed at Trimble Alignment Planning Solutions in Melbourne, Australia.

Mbalam
Mbalam is a place in Cameroon near the southern border with the Republic of the Congo where there are significant deposits of iron ore. The mining company is Sundance Resources Limited. Namesakes There are two other places in Cameroon with the same name. Railway A 510 km railway connection to a deepwater port is required to exploit these ore deposits efficiently. Several routes were planned using Quantm software. The railway will start at an elevation of about 650m at the mine, proceed along a fairly level alignment for 350 km, drops steeply for 100 km down to the coastal plain, then traverses that plain for 50 km to the port. The gradients generally favour loaded trains. In September 2010, Sundance Resources signed a memorandum of understanding with CRCC China-Africa Construction Ltd, which outlined construction plans for a 490 km railway linking the planned iron ore mines to a proposed port near Lolabé. Another Chinese company, China Harbour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geometric Design Of Roads
The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in geometric design are to optimize efficiency and safety while minimizing cost and environmental damage. Geometric design also affects an emerging fifth objective called "livability," which is defined as designing roads to foster broader community goals, including providing access to employment, schools, businesses and residences, accommodate a range of travel modes such as walking, bicycling, transit, and automobiles, and minimizing fuel use, emissions and environmental damage. Geometric roadway design can be broken into three main parts: alignment, profile, and cross-section. Combined, they provide a three-dimensional layout for a roadway. The alignment is the route of the road, defined as a series of horizontal tangents and curves. The profile is the vertical aspect of the ro ...

Track Geometry
Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces in the three-dimensional positioning of railroad track. The term is also applied to measurements used in design, construction and maintenance of track. Track geometry involves standards, speed limits and other regulations in the areas of track gauge, alignment, elevation, curvature and track surface. Standards are usually separately expressed for horizontal and vertical layouts although track geometry is three-dimensional. Layout Horizontal layout Horizontal layout is the track layout on the horizontal plane. This can be thought of as the plan view which is a view of a 3-dimensional track from the position above the track. In track geometry, the horizontal layout involves the layout of three main track types: tangent track (straight line), curved track, and track transition curve (also called transition spiral or spiral) which connects between a tangent and a curved track. Curved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSIRO
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government The Australian Government, also known as the Commonwealth Government, is the national government of Australia, a federal parliamentary constitutional monarchy. Like other Westminster-style systems of government, the Australian Government ... agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased ...

Melbourne, Australia
Melbourne ( ; Boonwurrung/Woiwurrung: ''Narrm'' or ''Naarm'') is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in both Australia and Oceania. Its name generally refers to a metropolitan area known as Greater Melbourne, comprising an urban agglomeration of 31 local municipalities, although the name is also used specifically for the local municipality of City of Melbourne based around its central business area. The metropolis occupies much of the northern and eastern coastlines of Port Phillip Bay and spreads into the Mornington Peninsula, part of West Gippsland, as well as the hinterlands towards the Yarra Valley, the Dandenong and Macedon Ranges. It has a population over 5 million (19% of the population of Australia, as per 2021 census), mostly residing to the east side of the city centre, and its inhabitants are commonly referred to as "Melburnians". The area of Melbourne has been home to Aboriginal Victorians ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport In Cameroon
This article provides a breakdown of the transportation options available in Cameroon. The options available to citizens and tourists include railways, roadways, waterways, pipelines, and airlines. These avenues of transportation are used by citizens for personal transportation, by businesses for transporting goods, and by tourists for both accessing the country and traveling while there. Railways Railways in Cameroon are operated by Camrail, a subsidiary of French investment group Bolloré. As of May 2014 Camrail operated regular daily services on three routes: * Douala - Kumba * Douala - Yaoundé * Yaoundé - Ngaoundéré * Kribi - Mbalam and xxxx in Republic of the Congo - under construction in 2022. * Edéa - Kribi - proposed connection to deep water port. There are no rail links with neighboring countries except Republic of the Congo. Roadways ''Total highways:'' 50,000 km ''Paved:'' 5,000 km ''Unpaved:'' 45,000 km (2004) Cameroon lies at a key po ...
