Comment Comment by leohutson This is a completely irrational way to look at it.The risk of a pedestrian fatality posed by a collision with a car travelling 30kmh is closer to the risk from a car going 5kmh than that of a car going 50kmh.Look at the chart here:http://www.victoriawalks.org.au/safe_speed/The risk from speed is non-linear.Risk the pedestrians in speed zone greater than 30kmh, because risk of fatal injury is far lower. parent leohutson 8 years ago
The risk of a pedestrian fatality posed by a collision with a car travelling 30kmh is closer to the risk from a car going 5kmh than that of a car going 50kmh.
Look at the chart here:

The risk from speed is non-linear.
Risk the pedestrians in speed zone greater than 30kmh, because risk of fatal injury is far lower.
