| A regional planning model is designed to facilitate coordinated land use and transportation planning, yet have a sufficiently simple structure to enable quick scenario turnaround. The model, TransPLUM, is built on two existing commercial software products: the Population and Land Use Model (PLUM); and a four-stage travel model implemented in a standard software package. Upon creating scenarios users are able to examine a host of results (zonal densities, origin-destination trip flows and travel times by mode, network link flows, etc) which may prompt modification of a reference land use plan and/or network plan. A zonal density-accessibility ratio is described: an index which identifies the relative utilization of a zone and which could serve as a coordinating feedback mechanism. The model was implemented for a pilot study area -- the Winnipeg Capital Region. Development of a baseline scenario is discussed. |
