Abstract
Vehicular traffic and ant-trail are two examples of systems consisting of interacting {\it self-driven} ``particles''. We represent ants by particles and capture their mutual influence in the ant-trail through inter-particle interactions. Extending the Nagel-Schreckenberg model, which is a minimal model of vehicular traffic on freeways, we develop a minimal model of ant-trail in terms of cellular automata. By a combination of analytical and numerical studies we demonstrate some unusual properties of the model; these predictions, in principle, can be tested experimentally.
