Experimental analyses of step extent and contact buffer in pedestrian dynamics

This study aims to quantify and develop a deeper understanding of the parameters that underpin development new, predictive, microscopic model pedestrian movement with potential accurately reflect complexity flow dynamics now into future. It presents results analyses two single file experiments designed physical space taken up by extent person’s stepping (maximum step extent) minimum distance between points inter-person contact (contact buffer) across range walking speeds. The successfully used high-resolution optical motion capture enhanced video analysis dynamic changes in gait spatial parameters, which were manifested as overlapping steps, extent, length, frequency, distance. sum buffer, at different speeds, was found be within few centimetres (headway), leading conclusion these are therefore key components for derivation spacing and, hence, overall crowd movement. work informs longer term aim developing mathematical has include demographics, ability cognitive capabilities. • Detailed capture, multi-planar experiments. Measures single-file flow. Personal “step extent” “contact buffer” summed distances. New theory, implement is described. Enhancements & implications considered.
