[/b]Obviously, people slow down when there's cameras. But the flip side is that people drive worse when they know we've turned traffic enforcement over to the cameras and, if you're on a street with no cameras (which is most of them), you can do anything you want. How do we know those two things net out to something better than when we didn't have cameras and motorists had to worry about cops pulling them over? [/quote]

Yes, there is evidence that traffic cameras make streets safer. There's no asterisk for *except in DC.[/quote]

Here's the number of people in DC killed by speeding drivers in past dozen years. Kindly point out to us where traffic cameras started making a difference.

2022 -- 9
2021 -- 12
2020 -- 15
2019 -- 10
2018 -- 9
2017 -- 12
2016 -- 8
2015 -- 11
2014 -- 12
2013 -- 11
2012 -- 5
2011 -- 15
2010 -- 8

Note: the higher numbers cited in another post include ALL traffic deaths, which include people killed by drunk and stoned drivers, pedestrians stepping in front of buses, motorists having heart attacks, etc. Obviously traffic cameras can't possibly do anything about those. [/quote]

Bueller?....Bueller?...Bueller? [/quote]

There have been multiple responses to your post.  You just don't like the responses.[/quote]

Actually, no one has answered the question. Tell us: which year is it?

You wouldnt think this would be that hard of a question if traffic cameras actually reduce deaths. [/quote]

You: Here are the last 6 times Mercury was in retrograde. How does this affect pizza delivery times? It should be an easy question to answer!

In other words, your question is based on inaccurate data and false premises. Multiple posters have explained this to you.

[b]
It's more like you didn't like that PP took the time to filter out the incidents in which speeding wasn't the determining factor.[/b]

Either way both sets of numbers have been pretty consistent in their pattern and there has not been a noticeable impact from the installation of cameras.[/quote]

I don't like that PP took the time and went to extra effort to produce even more inaccurate data, yes, you're right. Speaking abstractly, of course. If PP wants to waste their own time and effort that way, that's up to them.[/quote]

[b]It's not less accurate to filter by cause. [/b] But you should have noticed that they didn't provide the 2023 numbers.

The two things that stand out from both sets of data is that there was an initial drop between 2009-2011 and a big spike from 2022-2023.  That drop could possibly indicate the speed cameras have an initial impact.  But the quick reversion to the mean afterward would indicate either that the impact is short lived.

The spike is more interesting because that is the time frame when the realization that the police were no longer enforcing traffic took hold.  If anything the data shows that automated cameras are not not a replacement for enforcement by humans.[/quote]

It absolutely is less accurate. As has been explained. PP is cherry-picking numbers and then complaining that people don't want to engage with their cherry-picking as though it were valid.[/quote]

Except the gross numbers don't show a different pattern.  There was a spike down in 2012 which may be attributed to cameras, I don't know when they first proliferated, but which quickly reverted to the mean.  And there was a spike up in 2023 which correlates to the end of traffic enforcement.  Every other year is relatively constant.

[b]If cameras were the miracle solution claimed [/b]then should be able to see an impact.  Maybe if the numbers were all tied to population or traffic volume growth we'd see something more but otherwise it seems pretty consistent.  There's around 30 traffic deaths per year of which 10 are directly tied to speeding.[/quote]

There's another false premise. Nobody has claimed that automated traffic enforcement is the miracle solution.[/quote]

You've claimed they do something.  The numbers don't show that.[/quote]

Lots of studies say you're wrong.[/quote]

We're talking about the actual DC specific data, both with and without controlling for cause.  Any impact should show and yet it's more or less rangebound for the last 15 years.[/quote]
