Self-organized Trail Systems in Groups of Humans [.pdf]
"We have developed an experimental platform for studying the trail systems that spontaneously emerge when people are motivated to take advantage of the trails left by others. In this virtual environment, the participants’ task is to reachrandomly selected destinations while minimizing travel costs.The travel cost of every patch in the environment is inversely related to the number of times the patch was visited by others. The resulting trail systems are a compromise between people going to their destinations and going where many people have previously traveled. We compare the resultsfrom our group experimentsto the Active Walker model of pedestrian motion from biophysics. The Active Walker model accounted for deviations oftrailsfrom the beeline paths,the gradual merging of trails over time, and the influences of scale and configuration of destinations on trail systems, as well as correctly predicting the approximate spatial distribution of people’s steps. Two deviations of the model from empirically obtained results were corrected by (1) incorporating a distance metric sensitive to canonical horizontal and vertical axes, and (2) increasing the influence of a trail’s travel cost on an agent’s route as the agent approaches its destination."

A Big Little Idea Called Legibility
"The Authoritarian High-Modernist Recipe for Failure…

• Look at a complex and confusing reality, such as the social dynamics of an old city
• Fail to understand all the subtleties of how the complex reality works
• Attribute that failure to the irrationality of what you are looking at, rather than your own limitations
• Come up with an idealized blank-slate vision of what that reality ought to look like
• Argue that the relative simplicity and platonic orderliness of the vision represents rationality
• Use authoritarian power to impose that vision, by demolishing the old reality if necessary
• Watch your rational Utopia fail horribly

Central to Scott’s thesis is the idea of legibility. He explains how he stumbled across the idea while researching efforts by nation states to settle or “sedentarize” nomads, pastoralists, gypsies and other peoples living non-mainstream lives…"
