  1. Modified 3 – Tier Start Time 2008-2009 School Year

  2. Overview +30 Minutes Elementary Day Increase &6 of 7 3 Tier No Transportation Employees Eliminated 30 minutes can now be added to Elementary Student Day 6 of 7 requires modification to existing 3 Tier Routing System due to insufficient run time between High School and Elementary under present sequence. North End Schools Remain on 2 Tier System Bratt, Northview, Century/Carver, Ernest Ward, Molino Park Cost savings in excess of 1 million dollars

  3. Present vs. Proposed – Why the change? Present 6 of 7 reduces window by 25 minutes HS ES 40 40 40 MS 40 Proposed ES 70 HS 50 45 MS 50

  4. 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)

  8. Start Times Elementary School 7:30 High School 8:30 Middle School 9:30

  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

  10. Transportation General ScheduleMinor deviations will occur as a result of site specific operating constraints

  11. Savings Conservatively: $ 1,080,000
