Collective phenomena in laned-active-matter: blockages, percolation, and traffic*

We study the emergence of collective behavior in laned-active matter. Our approach combines empirical measurements and an active matter model. We explore dynamics in the presence of blockages and find connections with clogging, jamming and percolation transitions. Confinement to lanes decreases the number of accessible configurations of constituents, but also suppresses kinetically-trapped, disordered pathways, thus avoiding clogging. The results of these studies may inform how traffic can be engineered to deal with blocked lanes.
