Making Tough Choices Easier: A Prioritization Process for Pedestrian Infrastructure Improvements
The need
End-user interview results
Explainable to public and funders
Standardized Practical Safety-oriented
SRTSprojectidentification
Step 1: Prioritize schools
Step 2: Conduct field reviews of highest priority schools
RESULT: Ped infrastructure needs for highest priority schools
Group the schools
Based on Crash history Safety concerns Current or potential pedestrian use
Group the schools
1 Current walking, crash history. Ideally school interest
2 Current walking, public/school concerns.
3 Few students currently walk because of safety concerns.
4 Few students walk due to distance or costly infrastructure barriers
5 Students walk to the school & walking environment generally safe
Prioritize within Group 1 (maybe 2)
Use road and driver characteristics Traffic volume and speed Crossings Infrastructure
Additional considerations Geography
Low income communities

San Francisco’s Safe Routes to School Prioritization System
Presentation Overview
San Francisco & SRTS-SF Background
School assignment policy – commute study
Infrastructure prioritization system
Non-infrastructure prioritization system
Lessons learned
Background on San Francisco
49 square miles on tip of a peninsula
Over 800,000 people One city and one county SF has one public school
district w. 100 schools
SRTS in SF, before prioritization
School Area Safety Program – Bus and passenger loading– Traffic engineering requests around
schools– Evaluation sites for crossing guards– Apply for and manage SR2S/SRTS grants– Limited education/encouragement
Grant locations selected from:– Requests from schools/parents/residents– Requests from elected officials– Approved traffic calming plans– Staff-identified need

School Commute Study
Change in school assignment policy
UCSF conducted evaluation of school commute with over 12,000 students in K, 5th, 6th, and 9th grades
Study included – 72 out of 73 elementary schools– 12 out of 13 middle schools– All 14 high schools
SRTS prioritization system
ITE Journal article by Carl Sundstrom, Nancy Pullen-Seufert, et al (Feb 2010)
Used results from UCSF school commute study, crash data, demographic data
Modified procedure to fit needs of both infrastructure and non-infrastructure projects

SRTS prioritization system
Infrastructure improvements
– Prioritize schools with a lot of kids walking and safety concerns
Non-infrastructure projects
– Prioritize schools with the highest potential for more walkers

SRTS Prioritization System-Infrastructure
Prioritize schools with a lot of kids walking and safety concerns Step 1: Compile data
– Total school enrollment (SFUSD)– % who walk to school (UCSF)– Calculate total walkers– Pedestrian-involved crashes (SFMTA)
Step 2: Classify schools into (5) tiers– Calculate quartiles (total walkers, ped
collisions)– Classify each school
Step 3: Reality checkJohn Muir Elementary
Page & Webster Streets
SRTS Prioritization System-Infrastructure (cont.)
Step 4: Rank within tiers– % students living within 1 mile – % qualifying for free/reduced lunch– % of crashes during school hours– Severity of crashes
OR
Step 4: Feasibility screen– Work already planned/completed– Coordination opportunities– Scope budget v. grant budget– Scope v. funding source
Longfellow Elementary
Morse Street, east of Mission Street
SRTS prioritization system –Non-infrastructure (5 E’s)
Prioritize schools with the highest potential for more walkers Step 1: Compile data
– Total school enrollment (SFUSD)– % living w/in 1 mile (SFUSD +
Excel plug-in)– % who walk to school (UCSF)– Calculate # of non-walkers
Step 2: Rank by non-walkers Step 3: Solicit participation
Jefferson Elementary
19th Avenue & Irving St.
Lessons Learned
Focus on the goal Use what you have
(data, relationships) Take advantage of
time-sensitive opportunities
Be creative with funding

Study Goals• Develop a formalized method to prioritize
Miami-Dade elementary and K-8 schools for Safe Routes to School (SRTS) infrastructure improvements
• Develop SRTS plans and infrastructure improvements for 10 priority schools
• Prepare FDOT SRTS infrastructure funding applications for the 10 schools
Public Schools Database• Number of K-5/K-8 schools – 219• SRTS plans complete/funding applied – 62• Number of schools considered in 2011 – 157
The School Prioritization Process ranked the remaining 157 Elementary and K-8 schools based on need.

Prioritization Rankings
Prioritization is based on composite rank of individual factors
• Excerpt…
Prioritization Rankings• First county-wide prioritization of Miami-Dade
schools for SRTS improvements based on need• Quantitative process using available data• Assumes the six factors have a direct correlation
with a school’s potential for benefits
Potential Drawbacks• Does not include existing pedestrian
infrastructure levels– Field reviews were conducted to address this factor
Possible Future Modifications• Consider obtaining input from school principals
on the relative need for SRTS improvements– Perhaps through annual WALKSAFE survey
• Consider replacing “automobile ownership” with “percentage of students eligible for free or reduce lunch” as a proxy for income level– Available from Miami-Dade County Public Schools
at the school level
Top 10 School Selection• Used quantitative priority rankings as a starting
point– Removed magnet schools– Removed ideal scenario schools with few apparent
infrastructure needs
• Developed revised list of Top 10 Priority Schools to move into SRTS Plan and SRTS Application process
