Two sets of vehicles are timed over a kilometre section long and flows are also recorded. In the first set, four vehicles take 53, 56, 63 and 69 seconds when the flow is 1500 veh/hr. In the second set, four vehicles take 70, 74, 77 and 79 seconds when the flow is 1900 veh/hr. 1- Estimate the capacity (maximum flow) of a section. 2- Estimate average speed and density at flow rate of 800 veh/hr and 2000 veh/hr. 3- If the average speed of traffic is 60 km/hr, state the traffic condition (i.e. normal or congested)?
