The presence of other vehicles on the highway — including those that may be entering, crossing, turning off, or parked — definitely affects critical speeds.

The frequency of pedestrians is likewise an important factor. This is especially true at intersections with limited sight distance and at approaches to crosswalks.

The speeds shall be posted for off-peak hour traffic on an average weekday for the purpose of the procedures outlined herein. This will require drivers to adjust their speeds to lower values at times of peak hour traffic at some locations.
