Traffic flow on a three-lane (one direction) freeway can be described by the Greenshields model. One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hours. It is estimated that the capacity at the work zone will be reduced by 30% of that of the section just upstream stream of the work zone. The mean free flow speed of the highway is 55 mph and the jam density is 135 veh/mi/ln. If it is estimated that the demand flow on the highway during the emergency repairs is 90% of the capacity, using the deterministic approach, determine: (i) The maximum queue length that will be formed (ii) The total delay (iii) The number of vehicles that will be affected by the incident (iv) The average individual delay
