Study of Highway Vehicle Emission Inventory Procedures for Selected Urban Areas

摘要

The report identifies potential areas where additional information could bedeveloped that would assist states and urban areas in the preparation of mobile source emissions inventories. It includes a review of current mobile source emissions inventory practices in fifteen urban areas. Existing guidance-related materials were assessed in light of the results of the review, and recommendations for improved emissions inventory information or procedures were developed. The report describes the findings from the review of existing mobile source inventory practices. The problems and solutions uncovered from the state and local areas investigations provide a base of comparison for assessing both current and proposed EPA mobile source inventory preparation procedures.
