    United States. Federal Highway Administration. Office of Operations Research, Development, and Technology
    2018-11-01 | PDF
    Traffic congestion is typically caused by oversaturation, poor weather, vehicle crashes, work zones, poor signal timing, and special events. Over saturation occurs when more vehicles use a road than the road is designed to accommodate. The resulting congestion leads to unstable traffic flow, which instigates breakdowns and bottlenecks.The Federal H ...
