To address the dearth of knowledge about person-based and trip-level exposure, we developed the Icarus model. Icarus uses mesoscale traffic model—activity-based model—to analyze the heat exposure of regions of interest at an individual level. The goal with Icarus was to design accurate, granular models of population and temperature behavior for a target region, which could be transformed into a heat exposure model by means of simulation and spatial-temporal joining. By combining and implementing the most robust software and data available, Icarus was able to capture person-based exposure with unparalleled detail. Here we describe the model methodology. We use the metropolitan region of Phoenix, Arizona, USA to carry out a case study using Icarus.

This project explores the current building and land use within the South Mountain Village (SMV) area. The South Central Light Rail extension corridor serves as a focus area, including a half mile radius around each of the five proposed light rail stations. Research of the area included analyzing SMV demographic information, analyzing land use and zoning, conducting a site visit, researching case studies, and information on current City of Phoenix, and other transit oriented development plans. Based on the research and case studies, recommendations and propositions are made for:

1. The implementation of a community-based transit oriented development.
2. The integration of green infrastructure and urban agriculture.
3. Best land management practices.
4. Policy to ensure appropriate and sustainable planning for the future.
