Mobility infrastructure roads

Here we examine the development of mobility systems, primarily automobility. The three main supporting physical infrastructures for automobility are roads, vehicles, and fuels. We focus on the roads and vehicles first motor fuel will be treated in the subsequent section on energy. 

The ABM approach is employed in the modeling of car traffic because it is able to capture individual drivers preferences (Galus et al., 2012). In particular for electric car mobility, ABM takes advantage of high resolution road network maps and allows for an accurate mapping between the transportation network and the electricity infrastructure. However, in order to evaluate interdependencies between road and electricity network, detailed data on the electric equipment, drivers behavior, and power demand are needed. 

To correct this distortion. Martens proposes to use accessibility gains instead of time savings as the primary measure of benefit in CBA analysis. Accessibility gains refers to the fact that new road infiastmcture, for example connecting a rich residential area with a wealthy employment area, is not translated into less travelhng time for the mobility-rich. On the contrary, improved infrastructure means that they will have access to more places.
