Dick, in most cases, you are forced to use population data. If, for example,
the pedestrian is a 10 year old boy running across the road, you can use
"reasonable" upper and lower speeds for 10 year old boys: typically I use the
traffic engineering convention of 15th and 85th percentile speeds (the 15th
percentile speed is that speed which 15 percent of the population concerned do
not exceed; 85th percentile is that speed which 85 percent do not exceed).
Jerry Eubanks has published speeds in his book on Pedestrian Accident
Reconstruction (Lawyers Judges Publishing Co, AZ).
In some accidents, the pedestrian's acceleration is important. There is
nothing much published on pedestrian acceleration at the moment. A paper
covering acceleration (and speeds) of young pedestrians will be published at
the next SAE Congress, March 1-4 (paper 1999-01-0440).
