Engagement Summaries

Over 3,000 community members attended an event, took a survey, or commented on the final plan. Thank you to everyone who participated!

High Injury Corridors

The project looked at local and county roads in urban East Multnomah County, outside the City of Portland. It focused on high injury corridors (HICs), which are roads where the most serious crashes happen. Knowing where these crashes are concentrated helps in planning and prioritizing safety efforts to meet safety goals.

Systemic Safety Analysis

The systemic safety analysis examined the locations where there are crashes and the severity of the crashes. The analysis investigated trends in characteristics such as roadway speeds and volumes, intersection traffic controls, the presence of pedestrian and bicycle facilities, and the types of nearby land uses. Focusing on severe injury and fatal crashes, these variables tell the story of the safety of roadway users and informed project prioritization and countermeasure recommendations.

 

Plan Review 

This project was built upon many previous efforts and plans. This memorandum summarizes our key takeaways.
