Challenge

Washington County, Oregon continues to grow with industrial, commercial, and residential development. However, as the county grows, so does traffic. There is a need to service the changing traffic patterns of the county to provide a safe and efficient transportation system. This must be accomplished in a cost effective way by making the most of existing infrastructure and investing in smart technologies.

Solution

To address the challenge, Kittelson assisted Washington County in:
– Providing updated signal timing and intelligent transportation systems (ITS) support;
– Developing a plan to deploy Bluetooth readers on County facilities to monitor changes in travel time;
– Testing red clearance interval extension using radar detectors;
– Optimizing signalized operations at an intersection with frequent rail crossings; and
– Developing and implementing updated signal timings that are designed to reduce delay and travel time in key corridors.
