The accompanying figure shows the flow of downtown traffic during the rush hours on a typical weekday. Each avenue can handle up to 1500 vehicles/hour without causing congestion, whereas the maximum capacity of each street is 1000 vehicles/hour. The flow of traffic is controlled by traffic lights at each of the six intersections. (A) Suggest two possible traffic-flow patterns that ensure no traffic congestion. (B) Suppose the traffic flow along 9th Street between 5th and 6th Avenues, x6, is restricted due to sewer construction. What is the minimum permissible traffic flow along this road that will not result in traffic congestion?
