The paper "Natural Movement: Or, Configuration and Attraction in Urban Pedestrian Movement" by B. Hillier, A. Penn, J. Hanson, T. Grajewski, and J. Xu, published in 1989, challenges traditional theories that attribute pedestrian movement patterns to flows to and from 'attractor' land uses. Instead, it proposes a new 'configurational' paradigm where the primary property of urban grid form is to privilege certain spaces for through movement, suggesting that the configuration of the urban grid itself is the main generator of movement patterns. Retail spaces are located to take advantage of these passing trade opportunities, acting as multipliers on the basic pattern of 'natural movement' generated by the grid configuration. The configurational correlates of movement patterns are found to be measures of global properties of the grid, with 'integration' consistently being the most important measure. This has implications for urban design, indicating that well-used urban spaces are not determined by local properties but by their configurational relations to the larger urban system. The paper introduces the concept of 'natural movement,' which is the proportion of urban pedestrian movement determined by the grid configuration itself. Natural movement is pervasive and consistent, suggesting that it is the raison d'être of the urban grid. The authors argue that the modern tendency to see the urban grid as a byproduct of other processes is misconceived, as the grid itself is implicated in the generation of urbanism and its functional logic. The paper also discusses the application of 'space syntax' techniques to analyze the local and global structure of urban grids and their coupling with movement patterns. Case studies, such as the King's Cross development site, are presented to illustrate the relationship between configurational parameters and movement. The analysis reveals that the distribution of integration values in the axial map of the grid strongly predicts movement rates, even in the presence of attractors. The study concludes that configuration is the primary generator of pedestrian movement patterns, and attractors either equalize or act as multipliers on this basic pattern.The paper "Natural Movement: Or, Configuration and Attraction in Urban Pedestrian Movement" by B.
