Headway speed is defined as
WebSpeed is one of the fundamental characteristics of traffic flow and also one of the most influential risk factors – it is therefore important from the perspective of safety-related studies. For... WebWith increase in speed of the traffic, the minimum space headway increases, whereas the minimum time headway first decreases and then increases after reaching a minimum value at optimum speed of the traffic stream (Fig. 4.16). Maximum capacity flow is attained at this optimum speed when the time headway is a minimum.
