Speed Stats

Speed variance and crash risk

This graph shows that crash risk is minimized for those drivers travelling 10-15 km/h over the average speed. (Average speeds in BC are almost always over posted speeds.) Contrary to popular belief, there are more crashes at slower speeds than at faster speeds.

Raw speed and crash risk are not directly related, however, there is a U-shaped relationship which shows few fast drivers involved in crashes, and many more slow drivers involved in crashes.1

BC speed limits target safe drivers

Under current BC speed limits, safe drivers are included within the red enforcement zone (the fastest 15% of vehicles). Speed enforcement should only target the top 2-5%.

Enforcement tolerances set by police are often incorrect and result in even lower tolerances.2

Proper speed limits increase safety

Setting speed limits according to the standards of the Institute of Transportation Engineers (the 85th percentile method) will…
* focus enforcement on dangerous drivers, not revenue collection
* increase speed limit compliance
* provide greater consistency of speed limits
* reduce speed variance resulting in reduced crashes

The 85th percentile is the speed to which 85 percent of drivers travel below (under average, free-flow conditions).

@MineerBrett Keep in mind, health officials are also prone to run with their own agendas. Thinking traffic safety in BC which has been hijacked and now tilts in favour of cyclists and pedestrians to the detriment of drivers.
