CONTINUED DEVELOPMENT OF THE VANCOUVER MODEL

This paper describes the refinements made during 1975 to models used in an urban simulation project. The refinements include the estimation and impementation of equations for regional housing and the development and implementation of an algorithm that is used for demolishing a portion of the standing housing stock that is in areas where actual densities are less than permitted (zoned) densities. Minor programming errors have been eliminated, and the running time of the models has been improved. Principal conclusions relate to the increased reliability and realism of the models. A comparison of output from models in different states of evolution was made, and the current version is superior to earlier versions. The simulated output was compared with actual events in the region to verify that the simulations are consistent with recent development trends. Since the refinements have been encouraging, continued development of the model is warranted. The model is being continued, and the data base is being expanded so that empirical estimations of a number of relations can be included as ad hoc intuition. These empirical estimations should further improve the models. /Author/
