WebFor traffic class WebQuestion: Problem 3 (13) Assume traffic flow at an intersection follows the Greenshield's model with kj = 100 veh/km and Uf = 30m/s. The traffic light turns red at t - Os (no congestion before t) and turns green at t= 30s. The approaching traffic has a density of 40 veh/km. 1. What is the capacity of this intersection at the green light? (2) 2.
