The Public Works Department conducts "School Counts" during each
time period when children are going to and from school. The data
gathered includes the number of children crossing and the total
number of opposing cars and trucks. The data is summarized and a
crosswalk rating is derived by using the following: P = Sum of
the pedestrians during the peak a.m. 1/2-hour period and the
peak p.m. 1/2-hour period. V = Sum of the cars during the peak
a.m. 1/2-hour period and peak p.m. 1/2-hour period, plus three
times the sum of trucks and buses during the same peak 1/2-hour
periods. S = Adjusts for the speed limit through the crossing.
The base speed limit of 25 mph has a factor of 1.00. For each 1
mph increase in speed a factor of 0.05 is added to the base
factor of 1.00. Thus, the factor used for a posted speed limit
of 35 mph is 1.00 + (10 x 0.05) = 1.50. W = Adjusts for width of
street measured from external curb to external curb. The base
street width of 20 feet has a factor of 1.00. For each 1 foot
increase in
