a specific type of road junction where two highways cross, and all traffic movements are controlled by a single set of traffic signals located at a central point
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.
- The construction of a single-point urban interchange on the highway aims to alleviate congestion in our city.
- SPUIs are characterized by their efficient layout, which allows smoother traffic flow between highways and surface streets.
- Drivers approaching a SPUI must be attentive to signage and traffic signals to navigate safely through the interchange.
- SPUIs are increasingly popular in urban planning due to their ability to handle large volumes of traffic without extensive delays.
- The SPUI's design minimizes conflict points and facilitates quicker transit through major intersections.
