the picture attached represents the traffic entering and leaving a type of roundabout road junction in Continental Europe.  Such roundabouts ensure the continuous smooth flow of traffic at road junctions.  Construct linear equations that describe the flow of traffic along the various branches.  Use these equations to determine the minimum flow possible along x1.  What are the other flows at that time? (it is not necessary to  compute the reduced echelon form.  Use the fact that traffic flow cannot be negative.)

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.
