Distance and Density of Motorway Data

Pages under construction!




Using ArcView a value was assigned to each cell corresponding to the distance from the nearest motorway. A fine grid was also constructed across the study region and the values in the cells were coded with a value 1 if they contained motorway and 0 otherwize. This fine grid was then aggregated to a 1DM resolution grid where the values in each cell was assigned as the sum of values in the smaller grid. This gave a proxy for motorway density. The view above shows a classification of distance and density values also created using ArcView.

  • In future models other motorway related data layers could be useful, such as, distance from junctions, and density proxies at a larger scale aggregation.
  • As with the roads data the motorway data was stored in two seperate layers, one for density and the other for distance.
