Since our arterial street has reduced capacity, the cars all cut-through our neighborhood street. And just to be clear, we are not talking about a few cars. We are talking over 1,300 commuters a day.
Our one lane section of S. Fern St. simply cannot handle this traffic. According to Arlington County historical traffic counts, last performed in 2011 on our street, they measured 500 cars on a daily average. What a difference a “Complete Street” makes. We now have approximately 600 cars who rip down the same street in a three-hour period our school bus is dropping off children.
That does sound bad - though I'm not sure how much it's out of the ordinary. Still the only data the author gives is how much traffic has increased. Chris Slatt, in the comments, notes that "In 2016, there were zero pedestrian, bicyclist, or driver fatalities investigated by the Arlington County Police Department."
Anyway, if there really is rampant law-breaking (which is something I thought only cyclists did) then a few speed cameras and stop sign cameras should do the trick. I would not be too surprised if there were unintended consequences, and congestion might be one, but then this is a "pilot project"
With these changes in place, County staff are monitoring roadway operations using travel times and vehicle, bike and pedestrian counts. The design of the pilot project is flexible and may change as operations are monitored. The outcome of these measures will influence the ultimate cross section of the street and may lead to additional improvements as areas of opportunity are identified.
I don't know when they plan to present their findings, and since this was done 4 years ago, I suppose they should soon, but I'll reserve judgement until then.
