• While a reduced volume of traffic may reduce the amount of emitted pollutants, the program lacks the ability to quantitatively track this air quality improvement.
• A school participating in the Safe Routes to School program was selected based off of health risks associated with a high vehicular volume and the proximity of that traffic to the school. A survey was utilized to generate a vehicle inventory of faculty and parent drivers of this school. The inventory was applied to EPA equations to demonstrate the amount of emissions generated on a daily, weekly, monthly and school year basis. The equation was successful in generating quantitative data that demonstrate the total emissions generated by the school.
• EPA equations can establish pre-emission levels versus post-emissions levels. This comparison demonstrates the effect the program has on reducing emission levels of traffic generated to the school. Once applied on a larger scale, trends and applicability of the program in different regions, demographic areas and community types (rural, suburban and urban) can be identified.
• This identification will enable Safe Routes to School users to invest in individual initiatives that have been successful in similar areas.
