Emergency exits as bottlenecks in escape routes are important for designing traffic facilities. Especially the fundamental diagram is a crucial performance criterion for assessment of pedestrians' safety in facilities and an important basis for calculation methods. For this reason, several studies were performed during the last decades which focus on the quantification of movement through bottlenecks. These studies were usually conducted with populations of homogeneous characteristics to reduce influencing variables and for reasons of practicability.Studies which consider heterogeneous characteristics in performance parameters are rarely available. In response and to reduce this lack of data a series of well-controlled large-scale movement studies considering pedestrians with different disabilities was carried out.As result it is shown that the empirical relations ๐ฃ(๐) and ๐ฝ(๐) are strongly affected by the presence of participants with visible disabilities (such as wheelchair users) and the perception of the disability by the non-disabled participants. An adaption of movement speeds to movement speeds of participants using a wheelchair was observed, even for low densities and free flow scenarios. Flow and movement speed are in a complex relation and do not depend on density only. In our studies, the concept of specific flow does fit for the non-disabled subpopulation but it is not valid for the disabled participants. |
