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 2000s (i.e. previous to the introduction of tolls in SCUT highways), 35% of the Portuguese motorway network was toll-free, and Portugal was already considered one of the European countries with more toll roads. [25] [26] Following the introduction of tolls in former SCUT highways, 84% of the network had tolls, i.e., only 16% was toll ...

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 ...
Pavement performance models could be developed to predict a single distress such as a crack or the aggregate pavement condition index. Schematic deterioration of the condition of a road over time The increase in the IRI of a road in Texas.
