What term describes when two separate traffic streams join to form a single stream?

• A. Intersecting
• B. Diverging
• C. Crossing
• D. Merging

Answer: (D)

When two separate traffic streams come together to form one flow, the process is called merging. This term captures the blending action, such as vehicles from an on-ramp or neighboring lanes adjusting speed and gaps so they safely become part of the same through lane. It’s about fitting two inflows into a single stream in a controlled, coordinated way, often aided by design features like acceleration lanes and gap threading. Intersecting describes paths that cross each other at a junction, not joining into one stream. Diverging means a single stream splits into two or more streams. Crossing refers to paths intersecting at a point. Merging uniquely describes the act of blending into one flow.
