A section of highway has a free-flow speed of 110 km/hr, it was observed at a critical situation the density was 50, considering linear relationship between density and speed. A) Determine the capacity of vehicles in veh/hr b) If the flow on this highway was observed to be 1500 veh/hr determine the speeds at this flow. (Note: you have to draw all the relationships and put all the parameters on the diagrams as, q max, k cap, k jam, etc....)
