Sammamish’s new Intelligent Transportation System (ITS), intended to speed traffic along the main arterial, 228th Ave., through the City, has generated enough complaints that a refresh is likely, officials say.
The ITS is intended to synchronize traffic lights based on traffic demand through the entire corridor. The problem: left turn signals don’t “trip” as often as before, sometimes leading to three full traffic light cycles before left turns are permitted, according to some City Council Members at a recent Council meeting.
Complaints appearing on social media point to longer cross street red lights, even when there is little or no traffic on 228th.
On other occasions, cross streets have the green even when there has been no traffic.
City transportation officials are well aware of the problems.
