ABSTRACT
People's behaviour in the urban environment depends upon their perception. Their actions are conducted in the environment as perceived. Edges are the boundaries between different districts; they include railway lines, shore-lines, breaks in the sizes of buildings and the boundary at the city's edge between rural and urban land uses. Nodes are junctions of concentrated activity such as railway stations and main squares. Districts are named areas of the city with definite edges and distinct characteristics. According to the American urban researcher Kevin Lynch the building blocks of environmental knowledge are paths, edges, nodes, districts and landmarks. Paths, sidewalks, roads and canals, are the thoroughfares along which people travel. Space-time paths are best recorded in a diary. The diary should record the starting time of an activity, its duration and frequency, and the sequential order of activities.
