In Portugal, Porto completely replaced the traditional pavement of its city centre for granite blocks in 2005. [ 5 ] In Brazil, while São Paulo has almost completely replaced the Portuguese pavement sidewalks of Paulista Avenue with a cheaper, more regular type of concrete pavement since 2007, [ 5 ] other cities such as Rio de Janeiro still ...
The primary data set used in cost distance analysis is the cost raster, sometimes called the cost-of-passage surface, [9] the friction image, [8] the cost-rate field, or cost surface. In most implementations, this is a raster grid , in which the value of each cell represents the cost (i.e., expended resources, such as time, money, or energy) of ...
In the early 1980s the highway engineering community identified road roughness as the primary indicator of the utility of a highway network to road users.
Least-cost planning methodology (LCPM), also referred to as least-cost planning (LCP) is a relatively new technique used by economists for making rational decisions about investments in transport and other urban infrastructure projects. It is based on cost–benefit analysis. However, it is more comprehensive in that it looks at not only the ...
Here’s what it costs to buy a house in Portugal’s 30 largest cities: Lisbon: 1,096,000. Porto: 704,000. Vila Nova de Gaia: 452,000. Amadora: 530,000
The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section.The PCI is widely used in transportation civil engineering [1] and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service.

Portugal trafficked nearly 6 million Africans, more than any other European nation, but has failed so far to confront its past and little is taught about its role in transatlantic slavery in schools.
Some estimates put the cost of permeable paving at about one third more expensive than that of conventional impervious paving. [20] Using permeable paving, however, can reduce the cost of providing larger or more stormwater BMPs on site, and these savings should be factored into any cost analysis. In addition, the off-site environmental impact ...
