City of Beaverton, OR

The City of Beaverton, Oregon, implemented the flashing yellow arrow display at three study locations in April 2002 after having been granted authority to implement the flashing yellow arrow display from the City Traffic Commission and the Mayor’s office. A four-section all-arrows display was used. The local intersection management was controlled by a Type 170 controller with Wapiti W4IKS firmware. Special command box logic was required to implement the flashing yellow arrow indication. The City was able to use the same basic logic developed by ODOT for the Woodburn site in their implementation. To date, no problems had been experienced at the intersections.
