Evaluating the spatial transferability of an agent-based integrated urban model LIMITED

IUMs are large-scale models that simulate interactions between transportation, land use, and demographic systems. For example, the Simulator for Transportation, Energy, and Land Use for Regional Systems (STELARS) models demographic, vehicle ownership, and transportation dynamics. Making IUMs transferable across regions enhances computational efficiency and reduces recalibration costs. While transferability tests for individual components exist, full IUMs remain largely untested, emphasizing the need for comprehensive evaluation. Testing spatial transferability evaluates whether models developed for one region can predict outcomes in another, particularly in the presence of behavioral differences. For instance, data from the BC Activity Time Use Survey (BC ATUS) 2023 shows SUVs account for 37.22% of vehicle preferences in Vancouver compared to 24.22% in the Okanagan. This study evaluates the transferability of STELARS, developed for the Okanagan, to Vancouver by synthesizing Vancouver's population and generating components using BC Assessment dataset. Assuming similar behavior, initial transferability is assessed with metrics like Root Mean Square Error by comparing simulation results with Census and vehicle population from the Insurance Corporation of British Columbia. Ultimately, this study intends to determine whether large-scale integrated urban models are transferable across regions.
