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

5
Run Times Are Optimized

• Enough time to maximize bus capacity (one bus
  doing one bus worth of work)
• Enough time to make the complete run and still
  arrive on time
• Enough time to ensure maximized Bus Operator
  available work time within contract constraints
• More run time fewer routes to a point of
  diminishing returns

6
Not enough time to cover the whole attendance zone
ACTUAL - BEULAH WITH A 40 MINUTE WINDOW (7.03M)
7
Even worse with reduction in high school day
PROPOSED - BEULAH WITH A 20 MINUTE WINDOW (1.90M)

Start Times

• Elementary School 730
• High School 830
• Middle School 930

9
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
