Measuring the efficiency of a road network is currently an open question and many approaches have been suggested. In this paper we tackle this issue by proposing a network generation model, studying its properties and laying out a definition for the performance of a network. We then confront the real road network against the highest performance version of this model and define efficiency as the ratio between the performance of the real road network and our idealised model.
This is obtained through the definition of local and weighted versions of centrality measures. These measures deal with distance-decay effects and nodes having different masses.
In doing so, we remark that each possible network created with our model has a typical fractal dimension, and this permits to map a fractal dimension (a way to occupy space) with a performance.
