Ms. Becky Meyer Mr. Mark Bigelbach TRIP GENERATION -2- September 17, 2004 For the purpose of considering trip generation for the Academy and alternative uses for the property, trip generation projections have been established for the following three time periods: • Typical weekday AM peak hour (7:30 to 8:30 AM) • Typical weekday PM peak hour (4:30 to 5:30 PM) • Weighted average daily volume over the course of a year The AM and PM peak hours described above represent the times when traffic volumes on Vadnais Boulevard and other nearby roadways generally are at their highest levels. Trips Generated by the Academy A school day at the Academy extends from 8:10 AM to 3:00 PM. Academy trips can be classified as follows: student trips by van or bus, student trips where students drive themselves to class, student trips where students are dropped off by their parents /guardians, and faculty /staff trips. Based on information learned from Academy staff, 60% of the students arrive via van or bus service (the Academy currently provides five vehicles, with the potential to expand to seven once the enrollment grows). 20% of the students drive themselves to class, and the remaining 20% of the students are dropped off and picked up at the Academy. Among the students dropped off and picked up, half of those students ride in car pools (i.e., no vehicle trip is generated by that student). These percentages represent both the existing conditions at the Academy and what is expected to occur in the future. During the AM peak hour, all of the vans and buses arrive at the school, and 50% of the students that drive themselves arrive at the school. In addition, 50% of the vehicle trips involving students being dropped off at the Academy occur during the AM peak hour. The combination of these trips nets a total of 73 trips during the AM peak hour (51 into the Academy, 22 out of the Academy). Since the PM peak hour (4:30 to 5:30 PM) occurs well after the Academy dismissal time of 3:00 PM, the Academy will not generate much traffic activity during the PM peak hour. According to Academy staff approximately 20 students will leave the Academy during the PM peak hour, having remained after class dismissal for either a sports team or other functions. Assuming that 20% of the students remaining at the Academy have driven their own vehicles, and the remainder are picked up, a total of 36 trips are generated during the PM peak hour (16 into the Academy, 20 out of the Academy). The number of trips generated by the Academy on a weighted daily average basis for the year was determined based on information provided by the Academy and based on data published by the Institute of Transportation Engineers. The following components were used to determine the weighted daily average: - 2 8 -
