Current transport energy supply is finite; it will peak and decline. Replacement renewable energy resources will not match current consumption levels. Currently, transport planning does not consider energy supply disruptions or constraints, though energy supply fluctuations and shortages severely affect transport systems. A newly derived method was created to assess transport-energy reliance for suburban/urban areas. The method differs from traditional transport modelling because it is concerned with energy capacity, not road capacity. Transport behaviour occurring within the built environment and activity system of a suburb are analysed. A case study was performed so that the derived method could be applied to a real situation. Simulations of behaviour modification produced a maximum of a 64 per cent reduction in transport energy consumption for the study region. One hundred percent resilience/reduction (zero reliance on transport energy) was only achieved through modifying the spatial layout of the built environment. The method adds a new dimension to transport modelling: understanding the risk of reliance on transport-energy for suburban/urban areas. (a).
