Road. Analysis of average road width. Calculation of the average road width from the subvial geometries obtained from the cartography and the municipal street. The data is obtained from the formula Area/Perimeter*2. The data obtained are more representative in those roads that have a rectangular shape. In cases that are arranged with other geometries, the results are less precise.
