7 Project Goals 1) Improve traffic and pedestrian safety. 2) Create a database for each school. 3) Map walking routes to school. 4) Identify school safety measures. 5) Develop mitigation measures for 135 priority schools. 6) Identify 32 schools for capital improvements.

8 Project Tasks Complete: 1) Create GIS-based database. 2) Field Check/Update Walk-To-School-Maps. 3) Develop school safety toolbox. 4) Develop prioritization methodology and rank schools. Now: 5) Perform analysis and outreach at 135 schools. Next: 6) Identify 32 schools for capital improvements.

9 Project Database NYC Basemaps Schools Info. Crosswalk Types Safe Routes to School (SRTS) Traffic Signals Advance Warning Signs Stop Signs (two-way, allway) Street Directions Speed Humps School Catchment Areas Crash Data ( ) School District Boundaries School Zones

10 Data Collection and Field Work

11 Field Work & Map Updating Verify traffic safety plans. Revise/update. Integrate with NYC Data Warehouse

12 Map Development Create a traffic safety plan drawing for each school:

17 School Prioritization Methodology

18 Prioritization Methodology Process used to select 135 schools from 1,426 program schools for priority treatment

19 Program Schools by Borough and Type No. of Schools Public Schools Private Schools All Boroughs Public Schools 925 Private Schools 501 Total BRONX BROOKLYN MANHATTAN QUEENS STATEN ISLAND

20 Associate crash locations with schools Crashes associated with school 700 school buffer Crash locations

21 Severity Factors CRASH CLASS Fatal Crash (F) AVERAGE CRASH COST $3,468,000 SEVERITY FACTOR 3,468 Injury Class A (IA) $1,548,000 1,548 Injury Class B (IB) $385, Injury Class C (IC) $96, Property Damage Only (PDO) Non-Reportable (NR) $3,800 $1,
