perempatan

Perempatan is a term used in Indonesian and Malay to describe a road intersection where two or more roads meet so that traffic can cross, turn, or merge. It is a fundamental element of road networks, coordinating movements between different directions and serving both motorized and non-motorized traffic. While perempatan is commonly used to refer to junctions in general, persimpangan is a broader term that can denote any crossing, including non-vehicle crossways.

Typical configurations include four-way intersections (a cross), T-shaped and Y-shaped junctions, and more complex multi-leg junctions. A roundabout (bundaran) is a related arrangement that directs traffic in a circular flow at a perempatan to reduce points of conflict and improve flow. Perempatan may be controlled or uncontrolled: some operate with traffic signals, stop signs, or yield signs, while others rely on visibility and right-of-way rules. Pedestrian facilities such as crosswalks and pedestrian signals are often integrated to enhance safety.

Design and safety considerations focus on visibility, lane markings, signage, lighting, and pedestrian protection. Proper design aims to minimize conflict points, provide adequate sight distance, and manage turning movements efficiently. In busy areas, grade separation (such as overpasses or underpasses) may be employed to improve capacity and reduce congestion at perempatan.
