Abstract

For a proper understanding and modeling of pedestrian dynamics reliable empirical data are needed. Often the level of heterogeneity of pedestrians in laboratory experiments does not correspond with the level in the field. New studies have been carried out to examine one factor of heterogeneity by considering people with physical, mental, and age-related disabilities. In these studies a novel hybrid tracking system consisting of a camera system and inertial measurement units (IMUs) was used for the first time. The use of IMUs solves the critical issue of occlusion caused by the perspective view of the camera system and different body heights expected for participating wheelchair users in dense crowds. The IMUs act as an extension of the camera system to enable a complete data extraction of the participants’ trajectories and gathering of additional movement data. This paper focuses on the hybrid tracking system and proposes a tracking procedure for wheelchair users participating in these studies.

Thanks to the funding provided by the Federal Ministry of Education and Research of Germany (BMBF, FKZ 13N13946) the SiME experiments could have been conducted and the novel hybrid tracking system could be realized.
