    Lateral position of loading, which is an important input to pavement design and analysis, is a random phenomenon for human-driven trucks because they do not follow a straight path as they travel. Therefore, in the pavement-design community, this variable has been called “wheel wander” and conventionally considered in an implicit way. However, with ...
  • Mitigating Oversaturation With Cooperative Automated Driving Systems Applying Bundled Speed Harmonization Cooperative Adaptive Cruise Control and Cooperative Merging Applications to Managed Lane Facilities fact sheet
    Mitigating Oversaturation With Cooperative Automated Driving Systems : Applying Bundled Speed Harmonization, Cooperative Adaptive Cruise Control, and Cooperative Merging Applications to Managed Lane Facilities : [fact sheet]
    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 ...
