ABSTRACT: Many school districts have been proactive in investigating delayed high school start times because of the national scientific research validating the academic/health benefits of additional sleep for high school students. This presentation provides insight to implications of pupil transportation as it becomes a critical operational and fiscal aspect when altering school scheduling. GPI completed a study for Acton-Boxborough which analyzed the implications of merging from a three-tier start time/routing system to a two-tier start time/routing system and created a new optimized routing schedule for the school choice district. An in-depth analysis of the existing transportation practices resulted in the recommendation of several new policies with the intent to minimize the number of buses required for a two-tier merge including: planning based on actual ridership; removal of cul-de-sac service; "cluster" stops; student pick-up/drop-off time window; and district seat target rates. GIS tools were utilized to implement cluster stopping which located optimal bus stops to safely service more students in a shorter amount of time based on a district wide ?walk to stop? distance. Stop locations were determined via density mapping and students were assigned via the closest facility layer tool. GPI also utilized TransFinder, a school bus routing software, in conjunction with ArcGIS to map final routing into existing database for a seamless transition._x000D_ Overall, the merge resulted in a reduction of overall trips, dead head mileage, total bus stop time and trip duration, better utilization rates, and most importantly a 40-minute delay in school start time for high school students.
