Traffic Flow Diagram - Visual Guide to Vehicle Movement Patterns #3022329 (License: Personal Use)

This diagram illustrates how vehicles navigate around a central obstruction (gray rectangle) using four distinct traffic streams: red arrows show northbound and eastbound turning movements, pink and purple arrows depict southbound and westbound flows, and blue arrows indicate counter-flow or return lanes. Each arrow color represents a separate traffic phase or lane group, supporting analysis of intersection design, roundabout logic, or pedestrian safety planning.

Used in transportation engineering, urban planning, and driver education materials to explain traffic circulation, intersection layout, or roundabout operation; matches user intent for visual learning, infrastructure design reference, or traffic simulation modeling.
