Abstract
We report results of an empirical study of traffic flow on
ant trails. In analogy to vehicular traffic 'single-vehicle
data' like individual velocities, time-headways etc. have
been measured for uni-directional and bi-directional trails.
Apart from velocity and headway distributions also fundamental
diagrams are calculated. In contrast to highway traffic
no jammed regime is observed and the average velocity is
constant over a large density regime. We discuss our findings
in terms of the spatio-temporal organisation of the ants on
their trails and compare with theoretical predictions of a
simple cellular automaton approach.
