As a part of a series of 4 analyses looking at crashes involving injured adult cyclists in Berkshire, this looks at the ‘When’ dimension.
The chart below analyses the time of day for both weekdays and weekends and shows distinctly different patterns for cyclists. As expected there are peaks around the normal commuter times with the morning period being more condensed between 7 and 8 am, whereas in the evening it’s spread between 4 and 8 pm. Weekends tend to show a different pattern with a distinct lack of crashes in the early morning compared to weekdays. There is also a slight increase in crashes late at night between 10 pm and 1 am.
Crash rates on individual weekdays don’t vary by more than 10% with Wednesday showing the highest frequency and Friday the lowest. Weekends have much lower crash rates with 46% fewer collisions per day than the weekday average.
Only 20% of collisions are at night with 14% occurring in darkness (i.e. street lights not present and at night). It’s worth noting that in October and November, collisions in street-lit areas at night increase by more than 50% compared with the annual average.
