Observation of the east entrance time versus vehicle traffic reveals obvious . <br /> problems also. Several days show heavy traffic early morning hours (i.e., after midnight) and <br /> lesser traffic during afternoon traffic. Incremental time versus vehicle traffic for the east <br /> entrance during the fall semester is therefore considered invalid. However, the problem with <br /> the east entrance counter appears to have arisen in the data downloading stage, not in the <br /> actual recording stage (direct observation by SCI personnel of the counter's visual readout <br /> appeared correct with respect to passing vehicles). Therefore, daily counts recorded by SCI <br /> personnel are considered valid and are used in the traffic analysis. <br /> Vehicle counts recorded by direct observation of the campus' east entrance are summarized <br /> in Table 1 below. As shown in the table, during the times of direct observation. 64 percent <br /> of the traffic using the east frontage road was internal (i,e., to or from campus) and <br /> 36 percent was external (i.e., to or from Snelling Avenue), <br /> Table 1 .

The number of calendar days within each semester was used to compute an annual <br /> "weighted average" traffic at each location. Column 2 of Table 2 shows the number of <br /> calendar days within each semester that was used to determine the weighted average. The <br /> weighted average computation combined days when school was out of session (e.g., spring <br /> break, summer break, Thanksgiving, Christmas, etc.) with the summer semester traffic count. <br /> An academic calendar for the 1997-1998 school year is included in Appendix A. <br /> . <br /> mjw:mjw/raf:13444rpt.OOl 1-3 STANLEY CONSULTANTS <br />
