Pedestrian Safety & Mobility Assessment Tool

Background

Pedestrian Safety Impact Statement requested by Citizens’ Advisory Committee January 2010

Intended/Potential Uses:– ETDM, PD&E, 3R, local projects, assessing

developments

Align near-term projects with future land use and transit ridership

Background

Pedestrian Safety & Mobility Assessment Tool based on Pedestrian Environmental Quality Index developed by City of San Francisco

Tested on six area roads: Edgewater Dr., Park Ave., SR 50

Downtown, SR 50 West, SR 438, US 441

Scores

All based on 0 to 100 scale• Intersection Score • Walkability Score – combination of all

features related to the walking experience• Mid-Block Crossing Score – ease or

difficulty of crossing between intersections

Scores

• Block Intersection Score – average of intersection scores for a given block

• Total Crossing Score – combination Mid-Block and Block Intersection scores

• Pedestrian Trip Potential – estimate of relative potential for pedestrian trips along and across the road

Next Steps

• “Fine-tuning”• Technical memo to describe elements and

guide users in data collection and entry• Local governments develop land use

thresholds for Pedestrian Trip Potential scores

• Develop future transit ridership projections/goals
