Question

3. (20 marks) The capacity of a highway is suddenly reduced due to a closure of certain lanes in a work zone. If the Greenberg model describes the relationship between speed and density on the highway, determine the capacity if the jam density of the highway is 155 veh/mi, and the critical speed is 32.50 mph. Also, determine the percentage of reduction of the capacity of the highway at the work zone if the density at the vicinity of that zone is 85 veh/mi
