SPUI Meaning and
Definition
-
SPUI stands for "Single Point Urban Interchange." It is a type of road interchange that efficiently manages traffic flow in areas with high vehicle volumes and limited space. The design of a SPUI involves a single signalized or non-signalized intersection where a major roadway crosses over or under a minor road. This interchange is characterized by one bridge or underpass that allows free movement of vehicles between the major road and all turn directions on the minor road.
The SPUI design maximizes efficiency by minimizing conflicts and reducing delays. It allows for smooth traffic movements and better traffic control. Vehicles traveling on the major road can make left turns without impeding the through traffic flow, while maintaining appropriate right-of-way rules. The SPUI also includes dedicated lanes and separate signal phases for vehicles turning left, going straight, or turning right, effectively reducing the risk of accidents and traffic congestion.
Moreover, the SPUI design offers additional benefits such as increased safety, improved pedestrian and cyclist accommodations, and enhanced aesthetics. It can accommodate a variety of land-use conditions and provide better access to adjacent commercial and residential areas. However, the efficiency of a SPUI depends on traffic flow conditions, geometric design elements, and appropriate signal coordination.
Overall, the SPUI is a type of road interchange that efficiently manages traffic in urban areas, reducing delays, enhancing safety, and improving overall transportation efficiency.
