From @sjamieit.bsky.social:

The City of Ottawa posted the raw speed data from before and after Doug Ford banned speed cameras and the effect is so obvious it's not even necessary put a line marking when that happened.

This chart shows the percentage of drivers going 15km/h or more over the posted limit.

@c_9 What's the correlation with the KSI figures?

[c_9@mstdn.ca]

@TimWardCam i don't have the source data so can't speak to anything else about this yet.

[timwardcam@c.im]

@c_9 'Cos that would be the point - if removing the speed limit didn't affect the KSI figures, which is presumably what the speed limit was there for in the first place, then ... ???

[timwardcam@c.im]

@c_9 ... and if the KSI figures *have* gone up then there's the data to drive your campaign to reinstate the speed limits.

[andymor@cosocial.ca]

@TimWardCam @c_9 this is about the removal speed *cameras*, the speed limits haven't changed

[smn@l3ib.org]

@TimWardCam @c_9 what's KSI?

[timwardcam@c.im]

@smn @c_9 Killed and seriously injured.

[timwardcam@c.im]

@andymor @c_9 Ah but the graphic shows that in practice they have.

[andymor@cosocial.ca]

@TimWardCam @c_9 no it doesn't

[yacc143@mastodon.social]

@c_9
Ah. Obviously it raises one question, how is data collected.

Before is easy, the speed cameras measure the speed of everything that passes them, even the cats that go slower than the limit.

But afterwards? How was the data collected?

Sorry the data scientist in me wonders.

[nirak@hcommons.social]

@yacc143 I was wondering this too!

[anon20394702398750@mastodon.social]

@c_9

They're not speed cameras, they're surveillance tools that can be used as speed cameras.

[clickhere@mastodon.ie]

@andymor @c_9 Also - "and if the KSI figures *have* gone up then there's the data to drive your campaign to reinstate the speed limits" is probably the most revealing and utterly grotesque thing I've read someone say about road violence in a long time; and I live in Ireland.

@TimWardCam @c_9

[timwardcam@c.im]

@clickhere @andymor @c_9 That's likely to be how the transport engineers see it - the priority for spending on the roads is to reduce KSI. Councillors don't of course have to follow this advice and can spend on political projects instead.

[c_9@mstdn.ca]

@nirak @yacc143 My understanding is that the radar was still active, but the ticketing function was disabled. But I might be thinking of a different city and this uses a different data source.

[c_9@mstdn.ca]

@nirak @yacc143 Actually this page explains a bit, it’s measuring everything and reporting the averages. https://open.ottawa.ca/datasets/52f34797978c44c1820b8b2d7a4ae3ed

Off-topic, are you aware that the owner/operator of your mastodon instance is accused of defrauding the Inglewood Community League in Edmonton?

@TimWardCam @c_9 I want to know more than KSIs ...

In my little village in France many cars and trucks are going at >50kph
No child is allowed by their parents to roam the village on their bike with friends.
I'm wondering if their is a link between those two.

Making a car centric world have huge social consequences
