The average daily truck generation represents the number of truck trips that would be generated if each quarry produces and exports the same amount of material each day and each month of the year. On a yearly basis, there is generally one or more peak production months in which more aggregate is produced then would be the monthly average. As this could significantly increase the number of trucks within the >r study area and as how this could be a condition that could last for a month or more, a peak adjustment factor of 1.4 (40-percent increase) was developed to reflect this condition. The resulting estimated peak daily truck generation is shown in Table 36. As shown, up to 3,662 truck loads are estimated on a peak it production day,which would generate 7,324 two-way truck trips per day.

The number of peak daily two-way truck trips that would be generated by hour was estimated based on the 7,324 two-way truck trips shown in Table 28. The AM and PM peak hours were identified to include 6:00 to 7:00 a.m. (AM peak hour) and 4:00 to 5:00 p.m. (PM peak hour). As shown in Table 37, these two hours would have 730 and 172 two-way truck trips respectively that would be entering and exiting Route 132.
