Background

We are improving our RealTime system to make roads safer and help Oregonians get where they are going more efficiently by providing real-time traffic information to drivers.

The work includes installing RealTime Variable Advisory Speed signs along a busy stretch of I-5 south of downtown Portland from the Ross Island Bridge to Terwilliger Boulevard.

Work will continue through fall 2025. Visit the project website for more information.

How RealTime signs work

  • RealTime signs calculate and display advisory speeds based on conditions ahead using traffic sensors, weather sensors, and cameras along the roadway.
  • Providing this information to drivers improves safety and traffic flow by reducing crashes and their associated delays.
  • The information helps prevent rear-end crashes by warning drivers of slowdowns ahead.
  • It also gives drivers advance notice about speed changes ahead due to current conditions so they can make real time decisions.

ODOT project funding

While the funding crisis is having a profound effect on ODOT’s maintenance and operations, most construction projects will continue as planned. These projects are typically funded through separate capital programs, often with state or federal funds that are legally restricted to projects development and cannot be redirected for maintenance or day-to-day operations. Delays may still occur due to a reduced workforce. Fewer available staff for traffic control, inspections and project oversight could slow down timelines or introduce challenges in project delivery.
