Outline• Background

• Project motivation

• Methodology

• Preliminary results

• Next steps

Background• Strong community support for traffic safety• 2002 - Safe Communities Coalition formed

with grant from Oregon DOT• July 2003 - Portland City Council approved

the Portland Traffic Safety Coordination Council

• November 2003 - Community and School Traffic Safety Account created– Source: Annual increase in traffic fines

Community and School Traffic Safety Partnership

• Community-based, coalition-led effort to improve Portland's traffic safety

• Three focus areas– Bicycle and Pedestrian Safety– Safe Routes to School– Reducing Driver Error

• Strategic and Focused Enforcement

Distribution of Program ResourcesTotal ~$2.5 million

Current Enforcement Toolbox• Regular Traffic Division enforcement

• 10 officers

• Automated enforcement– Red light running cameras

• 6 cameras

– Photo radar• 4 vans

• Strategic and Focused Enforcement (SAFE)– Identified high crash intersections and corridors– Target missions and automated enforcement to

high risk areas

Map: PDOT

Project Objectives• Research new ways to identify SAFE

corridors– Use new GIS crash data– Try alternate network screening techniques

• Identify state-of-practice approaches

• Benefits– Allocate scarce staff and resources– Judges - maps as supporting evidence

Methodology• In GIS, attribute crashes to segments

– average 400 feet (short!)

• Compare crash performance– across similar street types– note: traffic volume data not available yet

• Identify segments “above average”

• Add “driver error analysis”

Enforcement Enhancements

• High profile missions

• Corridor branding and signage

• Increased fine zones

• PDA ticketing

High Profile Missions

Branding, Signage and Increased Fines

Next steps

• Incorporate traffic volume data

• Consider other screening approaches

• Use new PDA ticketing data

PDA Ticketing

• Saves time

• Reduces error

• Archives data

automatically

Conclusions• Efforts may improve corridor selection

– add in traffic volumes– consider intersections separately– additional screening techniques

• Further research on “Safety Corridors”– Branding and Signage– Increased Fines

• Work with PPB to use new data sources– PDA ticketing
