@mikesonn This isn't exactly data, but do you mean something like this?

One of the issues critical to the investigation, particularly when attempting to determine time and distance problems, is that of pedestrian speed. Next to perception/reaction time, there is probably no other area of collision investigation where there is such a disparity on what a specific value ought to be. Well known publications have established specific walking speeds, primarily for purposes of highway design and sign placement, at 4 feet per second and from 2.5 to 6 feet per second. In addition, many other publications and technical papers carry tables on pedestrian walking velocity based on empirical data. TableIV is such an example, obtained from Jerry Eubanks recently published textbook on pedestrian accident reconstruction. The figure above presents the same data in a bar graph format.
