A GIS Approach to a Distance-Based Pupil Transportation Eligibility System (PUTES) Office of Pupil Transportation Timothy Calabrese, Joanna Laroussi & Kevin Jenkins
Background Information  Over 1.1 million students  Approximately 450,000 receive MetroCards  Yellow bus service provided daily to 90,000
Business Rule #1  Eligibility for transportation based on grade and distance from school
Business Rule #2  Block Face Rule - students in the same grade range, attending the same school, and living on the same block must be eligible for the same level of service.
Components of PUTES  ArcGIS with Network Analyst  Street Centerline file  Geocoding Service  Transportation Eligibility Directory (TED)  Student information system  ArcGIS Server Web Application
TED
Elements Required for Creation of TED  Schools Point Feature Class  Network Dataset  Service Area Polygons  Python Script
Schools Point Feature Class: 2914 Schools The Bronx Queens Brooklyn Staten Island
LION street centerline file 210,579 segments
ModelBuilder
Full LION
Non-Street Features Selected
Non-Pedestrian Streets Selected
Pedestrian Network
Downtown Zoom: Full LION
Downtown Zoom: Non-Street Features
Downtown Zoom: Non-Pedestrian Streets
Downtown Zoom: Pedestrian Network
Service Area Polygon
Python Script  Add field to TED for a school Measure the distance from each TED segment to that school   Populate school column with A,B or C based on that measured distance and the block face rule Repeat for all 2914 schools 
Script overlaps SAP & Pedestrian Network to produce TED feature class
Student Information System  TED is uploaded to OPT SQL Server: Segments (134,000 rows) Schools (2914 new columns)  TED is sent to DOE student information system which “geocodes” each student to a street segment and assigns the eligibility code to the student’s record  Schools use systems to assess the transportation needs of their students
Student Data Geocode to LION Relate to TED Display in Student Information System Schools assess transportation needs of students
PUTES on the Web Displays Eligibility Zones
PUTES on the Web Perform Distance Checks Create Walking Paths
