Abstract
Walking speed of pedestrians is governed by many influencing factors such as density
of pedestrian, corridor facilities and so on. Since pedestrian have wide range of needs
and abilities, several approaches for determining pedestrian dynamics have been done.
Federal Highway Administration (FHWA) Manual on Uniform Traffic Control Devices
for Streets and Highways and Highway Capacity Manual 2000 includes a walking
speed of 1.2 m/s with zero elderly pedestrian involved. Many research studies have
been done in investigating the pedestrian dynamics which includes modelling and
simulating. However, so far not much attention has been paid to their qualitative
measurements. Besides, the study of pedestrian walking speed on corridor with corner
is relatively rare. Therefore, this study is carried out under two main objectives which
are to determine empirically walking speed of pedestrian for unidirectional free flows
at corridor with corner and also to quantify the walking speed of pedestrian by gender.
In this paper, we review the recent developments in pedestrian dynamics, by the
implementation of experiments under laboratory conditions with up to 60 pedestrians
and extraction of trajectories by video analysis in complex facilities of corridor with
corner, e.g. 60° corner, 90° corner and 135° corner. A straight corridor with 180° is
used as a baseline in this experiment. The data is analysed for each task given in which
different number of pedestrians and width of corridor are used for each corner.
Surprisingly, the result shows that average walking speed of male is lower than average
walking speed of female and applied at almost all tasks. Within three different corners,
135° corner facility shows a constant average walking speed of pedestrian even though
the numbers of pedestrians are increased. To quantify the second objective in this
study, the cumulative frequency graph of corridor walkway was plotted to determine 15th percentile and 50th percentile of walking speed both for female and male
pedestrians relative to parameters involved. The results are of particular importance for
designing the structure especially at walking corridor and also beneficial for the design
of an emergency response plan.
