A speed-flow diagram showing that traffic congestion is formed when vehicle volume or demand exceeds capacity

Summary edit

Description
English: Speed-flow diagram or speed-volume diagram: vehicle speed versus vehicles per hour passing through a point on a highway. The horseshoe shape indicates that vehicle throughput collapses when volume is 80%-100% of capacity. The traffic mode changes from free-flowing in the green area, to congested in the gray area. The red area marks rush-hour traffic.
