OAR 734-020-0470: Traffic Signal Spacing Requirement

The desirable spacing of signalized intersections on statewide and regional highways is 1/2 mile. The STRE may approve the installation of a traffic signal at locations where 1/2-mile spacing is inappropriate or infeasible due to: (1) Topography; (2) Existing or proposed road layout; (3) Identified traffic crash pattern; (4) Unique physical constraints; or (5) Existing or proposed land use patterns.
