Speed Histogram

The Speed Histogram report provides the speed profile at a site. A normal curve, with the same mean and standard deviation, is plotted to help gauge the skew of the speed distribution.

Optional vertical markers also show the speed percentile, speed pace and posted speed limit - all as specified in the report's Profile.

Right-clicking on the report and selecting Properties displays the report's options, most of which are self-explanatory.

The Set X-max to profile speed max option changes the maximum value of the speed axis to be the upper limit of the Profile's speed filter.

The Show as ogive option displays a cumulative total of vehicles.
