Shockwave theory traffic flow solved problems

WebThis part of the course Basics of Traffic Engineering (H111) deals with the theory of traffic flow. This theory studies the dynamic properties of traffic on road sections. We begin this … WebA shock wave is a discontinuity of flow or density, and has the physical implication that cars change speeds abruptly without time to accelerate or decelerate. This is an unnatural behavior that could be eliminated by considering high order continuum models.
