Why the Shift?Elementary constrained by the high school day When high school day is adjusted (less) there is

even less time to run buses in the morning and afternoon

Less time means more buses are required running with less occupancy – 2 & 3 buses doing what 1 could do if there was enough time

Can never lengthen the elementary day as long as the elementary student day is “inside” the arrival and dismissal times for High School

Run Times Are OptimizedEnough time to maximize bus capacity (one

bus doing one bus worth of work)Enough time to make the complete run and

still arrive on timeEnough time to ensure maximized Bus

Operator available work time within contract constraints

More run time = fewer routes to a point of diminishing returns

ACTUAL - BEULAH WITH A 40 MINUTE WINDOW (7.03M)

Not enough time to cover the whole attendance zone

PROPOSED - BEULAH WITH A 20 MINUTE WINDOW (1.90M)

Even worse with reduction in high school day

Resulting Run Reduction

Reduction of 90 Runs (42 Elementary, 25 Middle School and 23 High School)

1 Route is composed of 3 Runs (1 Elementary, 1 Middle School and 1 High School)

$36,000 three run bus cost or $12,000/run

90 Runs x $12,000 = $1.08 MILLION Saved
