French term or phrase: force d'écartement
I have hunted around but can find nothing satisfactory

Ces forces, dites sociales (Helbing, 1995) en raison du fait qu’elles règlent l’attitude d’un individu vers les autres, rendent le comportement des particules plus proche au comportement du piéton réel. Par exemple, on peut imaginer une force d’écartement qui fait légèrement changer de trajectoire à deux piétons qui avancent l’un vers l’autre (élément socio-psychologique), ou encore une force qui reflet la tendance d’un piéton à garder une certaine distance des autres piétons (paramètre culturel, coutumes). Le modèle mathématique présenté ici a été validé pour d’autres cas d’étude lors de précédentes recherches relatives à des situations d’évacuation d’urgence ou de gestion des flux de foules (Pecol, 2010, 2012).

English translation: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."

I used repulsive although feel it doesn't quite capture the image conjured up by "écartement". Thank you

spread distance


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

Notes to answerer
Asker: much of the text delves into physics so which term is best here? deflecting sounds right too


Peer comments on this answer (and responses from the answerer)
agree  Andrea Burde (X): I would be inclined to use " repellent force"

agree  Terry Richards: The term has probably been "borrowed" from physics.

deflecting force


Explanation:
Seems to fit the context of "slightly changing the path of two pedestrians..."

Asker: very good point Barbara

neutral  B D Finch: But they could be deflected towards each other, rather than away from each other.

  -> Of course - some pedestrians are repulsive, some attractive....
