Ultimately of course kids are kids and drivers are selfish.
Why not teach kids not to run into ANY street, to cross at the crosswalks, to look both ways, and that the people who live on that street need to be able to drive away from their homes so they can go to work and earn a living to feed those very same children? Of course, drivers are drivers and kids are selfish...
; resulting for safer public spaces for kids, pedestrians, pets, block parties, pickup soccer, and life in general.
There are other places than the middle of the street for "block parties" and playing soccer; places where cars are absolutely prohibited. So you suggest the selfish attitude that you can run a soccer match anywhere you like instead of in a place devoid of any possible car-player interaction?
And "life in general" is untrue. When fire response is slowed because they cannot navigate the streets safely in a timely way, people die. That's a fact.
I've been through this "traffic calming debate" over my residential street. People who wanted their kids to play in the middle of the street, or were just tired of other people driving by. People drive "too fast", they said.
So I did exactly what this guy did -- fifteen years ago. It's not rocket science. You take a video camera and a digitizer. You write a bit of software that gathers all the pixels that fall on a line from point A to point B on the street and store just those, because those are all you need. You measure the distance from point A to point B on the street. You look in the images for blobs moving along that line and time how long it takes for them to get from A to B. Distance divided by time -- speed. It's good enough for government work, because that is effectively the same way the government measured the speeds on our street. Pneumatic tubes separated by X distance.
I brought my results to the public meeting about the plan to deliberately degrade the road I've been paying taxes to maintain. I talked to the city engineer in charge of such stuff, showed him my numbers. He said yeah, they were the same as what he'd measured, but the city reports the results in a way that artificially inflates the "mean" speed. My numbers showed there was no speed issue.
I also pointed out that there was no speed limit sign on our street until almost a block after the end where people on a higher limit street turned onto it. They turn from a 35MPH zone onto a 25MPH zoned street but aren't told of the change until a block later. If speed is an issue, why isn't the street marked better? The engineer said that wasn't a problem because speeds were lower there anyway due to more cars being parked there on a regular basis.
Eventually the plan was dropped. Thank goodness. And we've had just the same number of gruesome deaths on our street before the plan was proposed as after it was dropped. Zero.
