PBOT updates committee on Vision Zero: focus on high-crash corridors, speed management and equity

Portland Bureau of Transportation staff briefed the Transportation and Infrastructure Committee on Vision Zero goals, recent data trends and safety strategies the city is using to reduce road deaths and serious injuries.

Wendy Collie, PBOT deputy director of transportation operations and the city traffic engineer, said Portland’s goal remains “0 deaths on our roadways,” and described the agency’s safe systems approach. Collie summarized recent crash trends and priority responses: the bureau’s high-crash network covers about 8% of city streets yet accounts for a majority of fatal crashes; speed, alcohol or drug impairment, and nighttime collisions are major contributors to fatalities.

The presentation reviewed data and countermeasures. Collie noted that 60–70% of fatal crashes occur on streets in the high-crash network and that speed and impairment are factors in a large share of fatalities. She described street reconfigurations (lane reductions), signal treatments and physical separation as core techniques and cited an evaluation that converted four-lane roadways to three lanes reduced all crashes by about 29% in studied cases. Collie also reviewed speed-management tactics—posted speed reductions, speed cameras, feedback signs and traffic calming—and presented the bureau’s practice of evaluating projects by comparing five years of before and after data where possible.

Panelists described lessons learned from other corridor projects. Kristen Hull and PBOT staff pointed to the Division Street BRT project as an experience that raised strong community concerns and underscored the value of early and sustained engagement. A PBOT staff member added a technical lesson: transit signal priority contributed substantially to travel-time savings on Division and that same treatment will be used on 80 Second Avenue.

Committee members pressed staff on implementation sequencing and funding. Councilors emphasized the political challenges of lane reconfiguration and the need for strong community engagement when projects change roadway character. Staff said many interventions are relatively low cost (signal timing and posted-speed changes) while roadway reconstructions and large capital projects require grant funding and time. Collie concluded by highlighting the need for continued financial and political support and cross-agency collaboration—especially with police, public health and emergency responders—to meet Vision Zero goals.

The briefing was informational; no committee vote was taken on Vision Zero during the meeting.
