4.Environmental Analysis _ <br /> regarding their production peaks. This adjustment is applied to convert the average annual daily — <br /> and peak-hour project traffic volumes to the corresponding volumes that would be expected <br /> during summer months, when production reaches seasonal peaks. Table 4.4-4 presents daily and <br /> peak-hour project traffic volumes expected during peak summer months. Employee trips to and <br /> from the site, as well as delivery trucks (cement, recycled materials, and other minor deliveries), <br /> were not included in the peak-hour analysis because these trips will not occur during the peak <br /> hour. The term trip refers to a one-way trip; thus a truck's roundtrip constitutes two trips.
