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.

The data: https://open.ottawa.ca/datasets/52f34797978c44c1820b8b2d7a4ae3ed

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.

@yacc143 I was wondering this too!

@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.

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

@nirak @yacc143 I understood it like that there is speed measurement (radar or induction loop underground) in place all the time, just the connected cameras for the speeding penalties were removed.
