school

slide-4
SLIDE 4
  • 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.

Business Rule #2

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
