spread distance Explanation: Albeit an educated guess. Might at least generate a bit of discussion. |

force d\'écartement repulsive force Explanation: A force that impels pedestrians to keep a distance from each other is the opposite of an attractive force and therefore must a repulsive force, even if it sounds strange to put it this way. The scientists who study this subject don't avoid the word: "Abstract. Although pedestrians have individual preferences, aims, and destinations, the dynamics of pedestrian crowds is surprisingly predictable. Pedestrians can move freely only at small pedestrian densities. Otherwise their motion is affected by repulsive interactions with other pedestrians, giving rise to self-organization phenomena. Examples of the resulting patterns of motion are separate lanes of uniform walking direction in crowds of oppositely moving pedestrians or oscillations of the passing direction at bottlenecks. If pedestrians leave footprints on deformable ground (for example, in green spaces such as public parks) this additionally causes attractive interactions which are mediated by modifications of their environment. In such cases, systems of pedestrian trails will evolve over time." See link below to "Self-organizing pedestrian movement" (PDF) Reference: http://bolay.biz/kai/english/envplanb.pdf |
