A RE-EXAMINATION OF THE TRANSPORT-DEMAND MODEL

The conventional transport-demand model is examined and found to be wanting in several respects, notably in its inability to take into account the effects of the transportation planning policies being tested on the land-use configuration and the weakness of the trip generation forecasting method. These problems are overcome in the model described in this paper, that allocates population into housing and workers into jobs and finds the resulting journey to work matrix. The location of jobs is found by modelling the various behavioural characteristics of industry; the available housing is found by modelling the location of housing and the pattern of out-migration. The model finds shopping trips generated as a result of the location of retail employment. Some planning variables can be specified exogenously in the model so that the effects in terms of the traffic flows and relocation of activities can be found. /Author/TRRL/
