Traffic Counts for December 2009

The Table below includes, for each day, the raw traffic counts at Point 1 and Point 2, and the calculation of the daily Cold Spring Road trips attributable to Westmont College. Formula per Condition 9:

Westmont Daily Trips = [Point 1 count] minus [Point 2 count] minus [10 daily trips for each of the five private residences between Points 1 and 2].

* - On 12/1/9 the battery in the Point 1 counter was inadvertently replaced with an unrecharged battery. The oversight was not noted until the next time the battery was changed on 12/17/9. Following the calculation used previously when a 3.5% decrease overall had been observed, for Point 1 we have substituted 107.123% of the highest same-day value on the corresponding day in 2007, the last period for which we have values for December (the count was interrupted in 2008 due to the Tea Fire)--backtracking from the last day of classes for the semester in order to account for the academic calendar shift. Consequently, the first four days of December shown above are actually factored from the last four days in November 2007. The figure 107.123 is the compounded value resulting from multiplying 3.5 times 3.5, once for each year since 2007. Because this approach results in an average that is marginally higher than the cumulative average for all other Semester Workdays since the start of construction, it would appear reasonable, and is favorable to the interests of our neighbors.

** - For the days on which the counts were erroneous at Point 2 we have substituted a value that is 95% of a comparable day in this period. This has the net effect if giving the benefit of the doubt to our neighbors.
