I've been corresponding with the Ward 3 Councilor at Large about this issue. My other half just went to the police station to talk with them about what could be done about this problem because he witnessed a very scary incident last Friday. The police all agreed there's a serious problem and said they don't like the revised traffic plan either. In addition to the Waltham St./Washington Street fiasco, they noted the problems at the intersection of Washington Street and Highland Street People don't know which lanes they need to be in and cars are almost getting sideswiped. (The police said their own police cars had almost been sideswiped.)

The problem is that during and post-COVID, traditional traffic patterns are disrupted and different The controllers can modify the cycle a little, but not much. Adaptive Signal Control fixes that, and I believe it should be implemented in WNSq.
As Jim Cote said, you can’t open up Waltham St to left turns, since those turning cars would take time aways from the vehicles proceeding westbound from Watertown St to Washington St. Also, the demand for a left turn onto both Waltham and Watertown St, would overwhelm the shared left turn lane, likely backing up traffic through the Highland intersection. Another “nice to have” would be opening up Waltham southbound to left hand turns, but that would similarly starve some of the other traffic moves and also bring more traffic to Waltham St.I had hoped that development on Washington St would somehow allow a new connector street between Washington and Watertown St, perhaps slightly west of Dunstan. That could become the new RT-16 and allow the irregular Watertown/Washington insection to be closed and perhaps converted to a park. If that happened, left turns onto Waltham would be possible and fewer cars would potentially be queued inside WNSq itself. It’s not a real proposal, just an idea.—Mike

Hi all,Maybe Michael or Jim know the answer to a few things I'm curious about.In one of the presentations leading up to the redesign of the square, there was a lot of emphasis put on traffic sensors activated lights and traffic lights that communicate with a central control center, and that was going to play a substantial role in reducing the "average" travel time through the square. My experience, however, is that the lights still seem to operate on fixed timing. Is this something that was abandoned along the way? Yet to come?Regarding that "average" trip time, did anyone ever go back and compare predictions with actual measured times and calculate the difference, and then re-examine the models and see where the assumptions failed?And also regarding the models, I was and continue to be an advocate of just opening up the intersection and allowing left turns to/from Waltham street, partially because people take them anyway but mostly because I live on a cut-through street. I was told that the reason it couldn't be done is because the models show that it would make traffic through the square worse. Given what we've observed actually happening, is that still true? Or would opening up that left actually make things better? Cars are spending time driving around the block instead of just taking the left and getting out of the way.Noa

Shari lays out some great points and then Michael explains some of these points in his usual detailed and informative manner. As a former City Councilor that has been involved in advising and watching the project from the beginning to now, I can first state that the original goal, in 2015 was to repair the underground infrastructure,fix the street lights (weren't working at all), replace the traffic signals and pave the road. (then the add-ons)Before I say anything else please note Lincoln's famous line: "You can please some of the people some of the time, but you cannot please all of the people all of the time." Your local Councilors can only rightfully pass this on to the traffic professionals as this is way too much for a person trying to please everyone.On a daily basis I travel through West Newton Square, Newtonville (Washington/at Walnut), and Auburndale, all of which had their intersections rebuilt in the past 10 years. None of them operate at all like they did in the past. That's a fact given all of the goals for the streets that we ended up putting a lot into small places. In most cases your driving world has been upended and it's not comfortable, but then you have to note that this intersection has a lot of moving pieces and if we use the Square then it's a fact of daily life
I really believe that the computer scenarios have a major flaw, which is the programs do not account for bad drivers, and drivers that simply don't care that they are circumventing the laws.My observation many times a day in West Newton Sq is that there are way too many people breaking traffic laws, and clearly doing so on purpose (illegal lane use in front of Tody's, left onto Waltham from Washington, left on to Washington from Waltham, etc.). Yesterday, our little Max was crossing Washington on one of those delayed Green walk lights and just missed getting run over by a person (We have the plate number) that careened through the square out of control, and not caring about traffic laws. Maybe cameras can change some of these habits.There is a capability built into the system to use active cameras to control the traffic flow and avoid the obvious long unnecessary delays, and this has to be prioritized. Then everyone has to realize that the goal was to add bike lanes, increase pedestrian ease of travel, and improve site lines all without taking private property (eminent domain) for increased space in the streets.The reality though is that about 90% of the time I'm satisfied with my travel through the square, and the other 10% is manageable if I breathe deep and realize that things just take a little longer now.Thank you.Jim

Dear West Newton Community,I think everyone has noticed the traffic increase lately, and we're finally seeing how the re-structuring of lights, lanes, and removal of islands is or isn't working. Some have said that the lights just need re-tweaking. Others have said that the slower movement of vehicles through the square is safer. As someone who lives close to the square and walks and drives there regularly, there are some very alarming things happening. I'm frightened that someone is going to get in a very bad accident, and possibly killed. The intersection I'm referring to here is where Waltham Street meets Washington St./Washington Street meets Waltham Street. There are other intersections that are also a concern.The situation: There are drivers going East on Washington St that are turning left onto Waltham Street, blatantly ignoring or not seeing the "No Left Turn" sign on Washington Street. I've watched car after car take this turn, sometimes making a very sharp turn. I've seen cars just barely miss pedestrians standing next to CVS (they jumped back from the curb). I've seen drivers take this illegal so fast as hard that they've almost lost control, nearly hitting several cars on Waltham Street that were waiting to turn right onto Washington Street. I've seen cars go through the red light on Washington Street and turn left - barely escaping a head on collision with the cars going West on Washington Street. And many times the cars speed up as they turn and then race down Waltham Street, which leads to a series of other problems. This is very scary stuff. Either drivers do not see the "NO LEFT TURN" sign or they are blatantly ignoring it, or a combination or both. People want to go where they want to go. But, it's dangerous. I do not believe it's an intersection that could be corrected with police presence. It needs structural change.Yellow road blocks (small poles) were put up on the small triangular traffic island (between CVS and The Bluebird Bar) to alert people to stay in their lanes as well as to the presence of the concrete island. Hopefully, they've mitigated some potential for accidents but they haven't solved the problems. More so, these yellow poles have been a very good *indicator* of the issues and problems in this intersection (and others). These poles have gone from yellow to streaked with black, to bent and torn, to being completely ripped off. The yellow poles have been replaced a couple of times, and then have gotten knocked down, and people continue to drive over the concrete barrier. While the previous larger island in the center of Washington Square (pre-new traffic flow arrangement) wasn't a favorite object, at least it worked and it controlled traffic. People couldn't turn with the barrier, although occasionally you would see people do an almost comical series of u-turns around the barrier as people tried to find their way.The intersection is not working. It's also not large enough to open it up (to allow for left turns), for then there would be speeding. The square is too congested and there are too many turns already. A sign and a camera with a high enough fine ($5000?) might deter someone from turning - though I'm not loving the idea of cameras and I just think people should drive responsibly and follow signage.The traffic on Washington Street is increasing and will continue to increase. There are a lack of sign lines in several places, such as turning right from Waltham Street to Washington Street. There are lane switches and turns - 3 or 4 times if one drives from Washington Street from the intersection of Chestnut Street to the Mass Pike.I've been corresponding with the Ward 3 Councilor at Large about this issue. My other half just went to the police station to talk with them about what could be done about this problem because he witnessed a very scary incident last Friday. The police all agreed there's a serious problem and said they don't like the revised traffic plan either.

(The police said their own police cars had almost been sideswiped.)
Ironically all of this is happening within blocks of or in front of the police station. (Again, I don't think police presence can work.) What's going to work? According to the police, they said a paper trail or notes or letters to the mayor. Please write. Please participate. (Ruthanne's email is rfu...@newtonma.gov)
Good questions, Noa - which I can't answer but nevertheless would like to comment on:
I don't know much about traffic modeling but I've modeled a variety of industrial processes and I believe that modeling traffic is generally similar to modeling factories - in one case we have vehicles moving along streets and roads, and in the other we have parts and assemblies moving around the factory floor. One major difference is that unless something breaks down, movements around the factory are controlled by predefined rules and known process characteristics, whereas traffic behaviors depend on decisions made by individual drivers, who can be tired, confused, distracted, or simply take an improper shortcut to try to save some time. It shouldn't be difficult to tell the model, for example, that one driver out of 200 will decide to take an illegal left turn, but how does the modeler know that this is the right number? To the extent possible all models should be validated by comparison to post-model observations, but this would seem to be particularly important when one is making assumptions about human decision-making. Like you, I'd be interested in seeing the comparison.
Also like you, I've seen no evidence that that traffic light
timing is adapting to vehicle flows. I've also waited at a red
light when it would have been safe to proceed. However this
situation may become less frequent as development continues and
more traffic goes through the square.
I'll bring up one more concern I have with the design of West
Newton Square - the apparent misalignment of painted lane markings
and overhead traffic signals. There are several places where, for
example, there are three individual overhead signal clusters over
two painted traffic lanes.

I'm presuming this meeting is happening this evening because it does not appear to be cancelled.
A totally different topic - Anyone else notice the trees that were planted on Waltham Street? The section between River Street and Davis Ave. They're pretty scrawny now but I'm hoping they will grow and in time not only make the street look better but curb the traffic as people tend to race up that part of the street as they're leaving WN square.
