Abstract: Exploring mice movement characteristics is a basic issue of using mice to study crowd behavior in evacuation due to cost and ethical consideration of pedestrian evacuation experiments. In this paper, single-file experiment was performed in a 2m-long passageway with trained mice. Mice movement characteristics were studied by fundamental diagrams in macroscopic view and the velocity–distance headway relation in microscopic analysis. The results show the decaying velocity with density at low densities, and show the non-strict relation of velocity and density at high densities. From microscopic perspective, random pause was observed, and mice can move forward together when overlap occurs. Further, the numerical simulation validates the scattered effect of the random pauses on the velocity–distance headway diagram, and indicates that mice velocity increase with distance headway sharply and then keeps stable. This study provides insights into mice movement as well as the similarities and differences between mice and humans in movement, and it may contribute to crowd evacuation studies.
