Overview serious crashes by day of week

[phonenumber]

If we slice the date/datetime information in a different way, then we can look at the crashes in a different way. In the chart below, we can see that most fatal crashes are recorded australia contact data on Friday and the least on a Sunday. We cannot deduce that Friday is a more dangerous day on the road since we would need to index these crashes against the total number of vehicles or journeys on the road on those days.


If we break it down in another way, then we can look at crashes by hour of day. Below is a subset of crashes since 2000 that shows peaks of fatal/serious crashes around the morning (small peak) and the evening rush hours (biggest peak). Unsurprisingly, the time of the day with the least number of fatal/serious crashes is in the middle of the night.

Overview fatal and serious accidents by time of day



There is a slightly different time profile for each of the days of the week, with the weekdays having distinct small peaks in the morning and bigger ones in the afternoon. The weekends have a different pattern with a much larger and flatter afternoon peak of crashes. Finally, it is also noticeable that Friday evenings (21:00-23:00) and Saturday evenings (21:00-00:00) have a distinctly different pattern of fatal/serious crashes to the other days of the week.
