Question

(10 points) 4. Studies have shown that the traffic flow on a single-lane intersection can be described by 130veh/mile, determine the velocity of the if the density on the approach is 45veh/mile and the space mean spee red interval, what length of the approach upstream from the stop line w the Greenshields model. If the jam density on the approach is stopping shockwave when the approach changes to red is 40mph. At the end of the l vehicles be affe the red interval is 35seconds?

Answer 1

Given hab, age-f -> Dengity on lane Ushen ed signal is not gkat ะ 45 vehlmie So, K= 45 vehl mile → grace mer speed is (v-40 mph 8iqral Inveval 3s scconds = 1089 ,55 ft
