Abstract
Speed is an important transportation consideration, because highway users relate speed to economics, safety, time, comfort, and convenience. Spot speed studies are designed to measure speeds at specific locations under the traffic and environmental conditions prevailing at the time of the study. There are two types of average speed measures that express the rate of movement or speed of a vehicle,. The first, time-mean speed, is covered in this chapter, and the second, space-mean speed is covered in Chapter 4.
