Traffic Intersection Design Diagram - Signalized Crossroads Layout #146089 (License: Personal Use)

This diagram illustrates a typical grade-separated, signalized four-way intersection with dedicated left-turn, through, and right-turn lanes in each direction. Vehicle movement is indicated by green arrows, red stop signals are shown at conflict points, and lane markings include dashed centerlines and solid edge lines. The layout supports efficient traffic management and pedestrian safety in high-volume urban settings.

Used in transportation engineering guides, driver’s education materials, municipal traffic planning documents, and smart city infrastructure presentations; targets professionals, students, and policymakers seeking to understand intersection design principles and traffic flow optimization.
