Kevin Lynch studied the mental maps and images that people form of cities. He identified 5 key elements that shape a person's mental image: pathways, edges, districts, nodes, and landmarks. Pathways are streets and paths that direct movement; edges are linear boundaries like walls; districts are recognizable sections of a city; nodes are strategic points like intersections; and landmarks are reference points like buildings. Lynch applied this framework to analyze the mental maps of Boston, Jersey City, and Los Angeles. His work aimed to understand how people navigate cities and design more legible urban environments.
