What is a "single-point urban interchange"?
A single-point urban interchange (SPUI) is a type of road design where all lanes of traffic are directed through a single traffic signal at the point where two roads meet, usually at a busy intersection. This setup allows vehicles to move efficiently through the intersection with fewer signal phases and reduces congestion. SPUIs are often used in urban areas where there is limited space and high traffic volume, as they help improve the flow of traffic by simplifying the intersection design.
