ABSTRACT
The purpose of transport planning is to provide the executing agencies with realistic advice on the potential and desirability of various transport developments or operations. Many of what the people now consider to be elements of the transport policy arena would not have been so considered fifteen or twenty years ago. This chapter excludes general income policies from consideration although it is known that several important categories of trip-making are highly income elastic. The main reason it is neglected is the people believe that the models have been developed and tested in countries where this technically-efficient assumption is not severely violated. Typically the conventional-disaggregate techniques have been designed to provide answers to the urban transport policy and planning problems of cities with well-developed alternatives to the private car for radial trips to/from the city centre. In the absence of explicit options for people to choose from, conventional choice-analysis methods become somewhat inefficient.
