Nearly two years after turning on the “Intelligence Transportation System” stop lights on 228th Ave. from one end of the City to the other, Sammamish is finally fixing it.
The ITS is intended to coordinate lights on 228th to give green lights and expedite traffic.
The problem: side streets and left turn arrows faced long delays, even when there was little or no through traffic on 228th.
Shortly after the Nov. 3 election, Sammamish Comment identified issues that face the City Council this year. These include:

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.
