Research Idea Scope

Air pollution across the nation has improved significantly over the past 20 years. Nonetheless, in highly populated area, sensitive populations living adjacent to high volume roadways are exposed to air toxics such as diesel particulate matter that impact their health. Communities across the country are voicing their concerns and want actions. DOTs need to know what measures can be put in place at the project level to improve both short- and long-term exposure to air toxics and diesel particulate from transportation sources. A compilation of cost and cost-effectiveness for these measures should be determined for all pollutants for which measures are proposed, with consideration for measures implemented singly or in combination. The proposed study would develop a practical guide for (or compendium of) mitigation measures for air quality for typical highway and transit projects.

Urgency and Payoff

Up-to-date guidance on air quality mitigation is essential to help DOTs address the public’s health concerns on air toxics and diesel particulate. This research idea will provide mitigation options for projects sponsors to improve air pollution for sensitive populations living adjacent to busy highways.
