The fall time change accident spike

There were two stories on Global Toronto last night that came from a digital-to-TV news flow.

The first was a look at the pedestrian accident spike that follows the fall time change– 10 years of Toronto collision data shows that the week after the clocks fall back shows a higher accident rate than the weeks on either side. When the time change dates moved starting in 2007, the effect also moved, showing that it isn’t something coincidental having to do with changing light patterns at that time of year. It seems to have to do with sunset suddenly changing its relationship to the evening rush hour.

Here’s the graph:

Here’s how it looked on TV.
