Abstract

A formula connecting the speed distribution measured in time with the speed measured in space is derived and applied to the cases of pearson type iii distributions, and lognormal distributions. In the first case, conversion tables from time to space measurements are provided both for the mean and variance and for the percentage of cars going more slowly than some fixed speed.
