Traffic detection during Highway 305’s widening

The in basket: Billy Jo Sprague and Otto Spieth both have questions about how the traffic signals are working on Highway 305 in Poulsbo while it is being widened.
Billie Jo says she’s sure that the traffic sensors at the light at Liberty Road at Poulsbo Village are turned off.
“But now that all lanes are open, will the sensors be turned back on soon?” she asked.

Billie Jo says she’s sure that the traffic sensors at the light at Liberty Road at Poulsbo Village are turned off. 
“But now that all lanes are open, will the 
sensors be turned back on soon?” she asked. “Driving through at 6:30 in the morning, it has turned red for me to let ghost riders through. No one is waiting on either side and I have to wait for the light to make its rounds until it finally turns green for me.”
Otto’s question is about the Hostmark Street intersection, which is operating now as what’s called a “split phase” for Hostmark traffic.
“West direction gets the left turn arrow and the straight ahead for a while,” he said, “and then the east direction gets the left turn arrow and straight ahead. In the future, is the state going to make it possible for both directions to turn left at the same time and then cut it off and allow both straight ahead directions to proceed?” 
The out basket: Jim Johnstone of the Olympic Region signal shop for state highways says both intersections probably will operate as Billie Jo and Otto hope, but not until final paving allows the detectors to be reinstalled, which could be as late as June.
At Liberty Road, he said, “there is no detection on the Albertson’s side,” so that traffic is controlled by a timer.  “We have to recall that movement every cycle regardless of the presence of vehicles. It will stay green for the maximum time that is set for that time of day.”
That is 25 seconds of green at 6:30 a.m. and 32 seconds after 6:45 a.m., when the lights along the highway go into synchronization. That won’t change until the detectors are re-installed.
Hostmark traffic is run on split phase because it’s safer while lanes are sometimes obscured during construction, he said.
“Once all of our detection and channelization issues are worked out, we will go to a full eight-phase system at Hostmark,” he said. Unless it one of those rare intersections where their computers tell them one direction on Hostmark should be a “trailing left” (in which left turners go after the through traffic, not before), the left turns in opposing directions will occur at the same time.
Of course, the question most people have about the Highway 305 widening (Billie Jo, included) is what’s the HOV lane doing on the outside? We’ll look at that next.

One thought on “Traffic detection during Highway 305’s widening

  1. The traffic lights on (Highway) 305 in Poulsbo are going to get somebody killed, if not someone getting angry and running a red light, then someone just having a heart attack out of pure frustration.
    I have been at the intersection of Bond and 305 waiting for a green light while a driver gets off the boat in Winslow. The driver leaving Winslow makes that light before I can make that light. They are the worst lights in the country!
    I can get to Bremerton High as fast as I can get to North Kitsap and I live on Viking Way. That is a fact.
