Abstract

This report seeks to provide recommendations for policymakers, urban planners, and transportation engineers on how to reduce traffic-related air pollution exposure in the built environment. The report summarizes literature and preliminary findings from a larger study that spatially and temporally characterizes air pollution distribution in an urban street setting given traffic and meteorological conditions. As part of this study, a mobile air monitoring platform measured ultrafine particle (UFP) counts on a 1-second basis along a 3 mile-long transect in Downtown Los Angeles. Ultrafine particle (UFP) pollution levels were elevated at intersections. While future work involving advanced statistical modeling is needed to understand how UFP plumes from accelerating vehicle queues disperse in the built environment, preliminary findings and existing literature inform smart growth and traffic management strategies to minimize air pollution exposure in urban street environments and near transit-oriented developments (TOD).
