There is a possibility that a fuel shock could occur; a severe restriction in the amount of fuel available for transport. This would restrict the movement of people. The spatial pattern of the capacity of individuals to adapt to a fuel shock is of concern to policy makers. Additionally the scope for policy makers to estimate the effects of schemes to increase adaptive capacity on groups of people at small geographies would allow them to target resources to more vulnerable areas.
An indicator is built which reports the proportion of people in an area who would have the capacity to make a journey such as their current commute immediately after the fuel shock begins.
