      abstract     = {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 𝑣(𝜌) and 𝐽(𝜌) 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.},
