I've sent emails to ODOT in the last couple years or any other state agency that may be involved Naming specific lights on specific main artery's that are blatantly obviously missed timed. My entire business is showing up to a problem site unseen, assessing the problem, assessing how to fix the problem and what it's going to cost to fix it and I've maintained a 4.75 star rating over nine years of business so I'm good at doing my job. The only response I ever got back was snarky about how I'm wrong and don't know what I'm talking about and they are right because they are intricately trained in how to weave baskets underwater and weld in space.
That's the same attitude the engineers flip to the field guys.
In Seattle, there were a few notable projects that went "off the rails" and made things worse.
Those who know the area will be familiar with these:
Several years ago, they made Mercer St 2-way. At first, it was bad enough. But, to exacerbate the situation, the engineers decided they "must have" adaptive central control over the traffic signals on this stretch of Mercer.
Well, the system uses algorithms to figure out the best traffic flow, however, those algorithm rely on good data in to get good operation out. Well, when the system glitched, or the input data was bad, the central system would really eff things up. It got so bad, we even powered down and bagged one of the signals for a few years to try and figure out what was wrong.
People are constantly getting stuck in intersections because when their light turns green, the next light turns red (these intersections are very close together, Google it, stories will come up) causing people to inadvertently "block the box".
Do you know what the solution for that issue is? They installed cameras to fine/ticket those who get caught blocking the intersection. Isn't that nice?
Another one, using that same central system....
When the tunnel that replaced the viaduct was completed, it emptied into the SLU area near the aforementioned Mercer St....
Well, they put those signals on central control too.
When the central control would glitch, the signal that controlled the intersection at the north tunnel exit would stick red, causing traffic to back way up into the tunnel. It could take an hour before someone called us out to troubleshoot it. Wanna know how stupid this central control system is? When the light was stuck red, it would still stop cross traffic and service the corresponding ped signals....so, you'd be stuck forever at a red light, watching the peds go into walk on a regular basis.
Guess how we techs fixed it....
We unplugged the controllers from the Ethernet and told the engineers that they need to figure it out..... Unplugging a controller from the Ethernet is a big deal, because although it makes it impossible for central control to cause trouble, we can no longer remotely manage those unplugged intersections.
Crazy thing, they ran better using their internal pre programmed data.
