For the summer of 2007, six high school students participated in an air-quality survey. During a typical day, they go out on two two-hour shifts carrying instruments that measure different aspects of the air. For one of the hours in a shift, they walk on a predesignated route. For the other hour, they count cars and log traffic flow. There are also fixed site equipment that monitor the air around 1534 Tremont st. There are also two automatic traffic counters that count traffic infront of 1534 Tremont st and another on Huntington ave.
