What is the name for the roadway length designed to accommodate two traffic streams merging and then dividing within a short distance?

• A. Phase
• B. Weaving Sections
• C. Saturation Flow Rate
• D. Arterial Highway

Answer: (B)

Weaving sections describe the stretch of road where two traffic streams must merge and then diverge within a short distance. This part of a freeway is specifically designed to let vehicles entering from on-ramps blend with the mainline and then separate to exit ramps, all in a limited length. The term “weaving” captures that continuous intermingling and the need for enough space so drivers can perform merging and diverging safely without disrupting through traffic. Good design provides enough weave length to accommodate these movements at the prevailing speeds and volumes, reducing conflicts and keeping the flow steady. Other terms don’t refer to this merging-and-diverging design feature: for example, phase relates to signal timing, saturation flow rate is a traffic capacity measure, and arterial highway is a road type, not the specific segment where two streams weave together and apart.
