This paper was presented at Session 25-Transport and Accessibility. A systems approach is used to analyse the faults of the conventional evaluation methods used in the land use/transport planning process. The approach shows six features which are essential for an improved evaluation process, including the use of objectives relating to all relevant community goals, the avoidance of sub-optimal objectives and the investigation of distributional impacts. Accessibility indices are appropriate measures of performance in such an approach because they measure the choice of opportunities available rather than traffic demands. They measure an output of the urban system, not just the transport sub-system. Two accessibility indices have been developed and compared using data from the Sydney area transportation study and the 1971 census of population and housing. The two measures were found to be highly correlated, although one measure contains behavioural elements whereas the other is a measure of physical accessibility. There was found to be as much variation in accessibility between occupation groups as there is between municipalities in inner Sydney suburbs. Improvements in the road system would exacerbate the inequality of access to job opportunities in the inner suburbs, because the majority of non-professional workers do not have cars available for the journey to work (a).
