How scoring works You complete the PEQI form on every street segment and
intersection to get an aggregate score.
Data is used to compute a PEQI score
0-20 pts “environment not suitable for pedestrians”
21-40 pts “poor pedestrian conditions exist”
41-60 pts “basic pedestrian conditions exist”
61-80 pts “reasonable pedestrian conditions exist”
81-100 pts “ideal pedestrian conditions exist”

Boyle Heights Living Streets Initiative 3-pronged strategy Demonstration Projects: Design/build simple, easily removable elements such as sidewalk living rooms and street porches. Prototype Streets: Build three prototype Living Streets in the Boyle Heights neighborhood selected and designed by community residents. These streets feature permanent street improvements such as state of the art pedestrian crossings, bicycle lanes, street trees and bioswales. Implementation Blueprint: Monitor and catalogue the main obstacles to implementing the prototype Living Streets, and identify practical ways to overcome them. Make this blueprint available to others on the Living Streets LA website.

Need for App2.0 adaptability Benefits of App
Time savings calculating scores and mapping
Reduces user error
Need for Adaptations
PEQI 1.0 App is static: user can only change the questionnaire and weights of paper form
Programming in end-user customization of App allows for organizational & community flexibility
Better integration with G.I.S. and analytic software
Improve training and protocol materials

Paper version 1.0 2.0 SFDPH undertook 2 year upgrade process of survey.
Evidence-based upgrades: Changes made based on the most up-to-date information in transportation and public health journals on pedestrian safety, pedestrian comfort, and walkability.
Tested for inter-rater reliability: changes made to improve the likelihood that two independent auditors would rate the same intersection or street segment in the same way.

Proposed Work: Phase I
Upgrade PEQI 1.0 PEQI 2.0 Improve access, training materials and functionality
Field test PEQI 2.0 with SFDPH and other groups
Evaluate PEQI 2.0 as: stand-alone app
tool to stimulate community to neighborhood change (built environment and health proxies)

Proposed Work: Phase II
Expand app user profile (NGOs, Cities, Counties…)
Coordinate with PEQI 2.0 users to monitor street-level improvements
assess magnitude of change (built environment and health).
Evaluate data and propose policy solutions based on results
56
![Page 57: PEQI 2.0 Mobile App Upgrade Information 2013](https://reader036.fdocuments.us/reader036/viewer/2022082209/586beaa91a28ab69708b8429/html5/thumbnails/57.jpg)
Proposed Work: Phase III Integrate PEQI data, other mobile sensing & archival
data into a singular platform (GIS? Google?) BEQI (Bicycle Environmental Quality Index)
Pollution exposure (noise, particles, etc.)
Other built environment influences on health
Further expand PEQI 2.0 and other integrated mapping apps to facilitate built environment change for health (national and beyond)
Improvements in the built environment, pedestrian safety and public health while reducing GHGs.
