The purpose of weaving sections in roadway design is specifically to accommodate two traffic streams that are either merging or dividing within a short distance. This is crucial in areas where different traffic flows need to interact, such as near interchanges or highway ramps, where vehicles from an exit ramp might be entering the mainline while others are merging off onto an exit. The design ensures that these movements can occur without causing significant disruptions or increased collision risks.

Weaving sections are designed to facilitate smooth transitions while maintaining traffic flow. When vehicles are merging or diverging closely together, it's important to manage how they interact, which can lead to efficient movement and reduced chances of accidents. Properly designed weaving segments take into consideration factors such as speed, spacing, and volume, making them vital elements in roadway safety and functionality.
