Track: Environmental Management
Author(s): Simon Choi, Ying Zhou, Ping Wang, Sung Ho Ryu

Southern California Association of Governments (SCAG) has conducted environmental justice (EJ) analysis as a part of plan assessment process since 1998 Regional Transportation Plan. EJ analysis is designed to measure the benefits and costs of a proposed plan on people, in particular, of low income or minority. Aviation noise from aircrafts, as one of plan impacts, should be properly measured for the EJ analysis. The purpose of this study is to measure accurate spatial distribution of aviation noise and affected population in the vicinity of airports using the GIS approach. The study shows how to convert spatially aggregated socioeconomic data or aviation noise in the noise contour into the smaller raster cell level data using the integrated noise model, the discrete choice model, and socioeconomic and land use data from aerial photographs, local general plans, and the regional vision land use strategy.
