Research for the AASHTO Standing Committee on Planning. Task 68. Implications of New 8-Hour Control Strategy Development on Transportation Programs, Policies, and Projects

This report is designed to support transportation agencies in identifying and evaluating candidate strategies for implementation under the new 8-hour ozone standard. Few studies have been conducted to determine which control strategies are better suited to reducing emissions of ozone precursors over the longer timeframe. This report provides information on tropospheric (ground-level) ozone formation and factors affecting ozone concentrations, the effects of advances in emissions control technology on future emissions rates, and the effectiveness of transportation strategies in reducing motor vehicle emissions and 1-hour and 8-hour ozone concentrations in a typical urban area.
