Motivated by both the power and limitations of existing PSSs, this paper aims to develop and apply an online, easily navigable, and engaging PSS based on programming-based algorithms. The proposed PSS tightly couples large scale economic and land-use simulation models simultaneously to support land-use change projection, planning scenario testing, and impact assessment. Economic simulation is conducted using a regional economic input-output model (REIM), which uses investment scenario inputs to predict employment and changes in economic output. Land-use change is simulated using a dynamic spatial land-use model, the Land-use Evolution and Assessment Model (LEAM), which was originally developed by an interdisciplinary research team at the University of Illinois with support from the National Science Foundation [15]. The LEAM model treats a wide range of biophysical and socio-economic variables that positively impact urban development (e.g., employment opportunities, public services, green spaces) as “attractors.” The accessibility to attractors is estimated by a gravity model based on road networks, travel times, and the “weight” of these attractors.

N2 - Planning support systems (PSSs) should generally be designed to promote the partici-pation of stakeholders in planning and design processes through the delivery of useful, localized information, an ability to collect feedback, and an ability to model and test various ‘what-if’ scenarios. This paper focuses on such a PSS tool. The tool integrates the Land-use Evolution and Assessment Model (LEAM) with a Regional Economic Input-Output Model (REIM) in a tightly coupled com-putational process made accessible to stakeholders through a web-based PSS. The integrated tool allows for users to easily navigate the models and test land use and economic scenarios without expert assistance. It also keeps simulations updated with dynamic inputs and engages users in PSS development and application through responsive feedback to enhance plan-making abilities. In this paper, we demonstrate an application of the LEAM-REIM PSS in Sangamon County, Illinois. The application demonstrates an ability to provide more efficacious and detailed land use estima-tions through the connection of economic and land-use models, allowing users to easily engage with, navigate, and respond to scenario tests. We discuss the PSS tool, model integration approach, and detailed application to assess its usefulness in urban planning and design. We also propose some opportunities for further research.
