Vibration Driven Vehicles Flowing Through Bottlenecks
In this work, we report the behaviour of an ensemble of self-propelled particles that flow through a bottleneck. In particular, we studied the emergent dynamics when mechanical vibration driven vehicles (VDVs) are placed in a hopper-like geometry on a horizontal plane. For this particular geometry, the particles present organized structures determining the size of the group of agents crowding at the exit door. Furthermore, we show that the latter has a strong influence on the distribution of time intervals between the exit of two consecutive vehicles. We found these results to be compatible with the faster-is-slower effect interpreting the term ‘faster’ as ‘higher pressure’.
