If this data is analyzed in JMP:
probability of death if vehicle speed is <= 30 km/h =
= (0.0001333 * ((velocity)^2)) - (0.000667 * (velocity))
probability of death if vehicle speed is 30 - 54.9 km/h =
= (0.0005921 * ((velocity)^2)) - (0.020565 * (velocity)) + 0.1693269
probability of death if vehicle speed is >= 54.9 km/h =
= (-0.001041 * ((velocity)^2)) + (0.14308 * (velocity)) - 3.91736
Limitations:
• The size of the vehicle and the manner of the impact would affect the mortality rate.
