Plot the relationship between the approach speed v and thelength of the dilemma zone for the following data:a2 = 0.5g, δ2 = 1.0s,w = 65ft, L = 15ft, and τ = 4.5s (wherea2 is the acceleration, δ2 is the perception reaction time, w isthe width of the intersection, L is the length of the vehicle andτ is the duration of the yellow phase of the trafficsignal). To help you interpret this plot, draw anotherdiagram in which the v versus xc andthe v versus xo relationships aresuperposed
