Development and Implementation of Regional Planning Model : Use Southern California Planning Model ( SCPM ) as an Example

Regional planning model is critical for the planning support system employed by Metropolitan Planning Organization (MPO). As an example of regional planning model, Southern California Planning Model (SCPM) incorporates economic input-output analysis to a spatial allocation model and reports results in considerable spatial detail. The economic inputoutput model is used to estimate the indirect and induced effects of a plan, project or policy. The direct effects are allocated to the impacted areas, the indirect effects are allocated to zones according to base-year proportions, and the induced effects, i.e., the effects resulting from household expenditure changes, are distributed spatially throughout the entire region via the spatial allocation model. SCPM has been developed by a research group at University of Southern California (USC) since the early of 1990s (Richardson, et al. 1993; Gordon, Richardson and Davis, 1998). Various versions of SCPM have been developed since then to address the complex problem of spatial economic impact analysis. SCPM has been widely applied in Los Angeles and other regions and steadily updated over the years as new and revised data sources became available (Cho et al. 2001). The most recent version introduces time-of-day choice to facilitate an understanding of the effects of peak-load pricing on a complex urban land usetransportation system (Pan et al. 2011). _______________________________________________________ Q.
