Abstract
Pedestrian walking speed is influenced by the following factors such as density
of pedestrian, width of walkway, and angle of walkway. There are many research
studies that have been done to analyse the pedestrian dynamics on unidirectional
pedestrian flows on angled-walkway. However, the study on the movement of crowds
on bi-directional flow at the angled-walkway is relatively rare. Therefore, this study is
conducted to determine empirically walking speed of pedestrian for bidirectional free
flows at angled-walkway. For this experiment, 60 participants are assigned to perform
various tasks in walking at straight walkway, as the velocity was used as a baseline to
in this experiment before the pedestrians were asked to traverse along different widths
(1.5m, 2.25m and 3m) of 90°angled-walkway. The videos have been captured using
GoPro Camera mounted on the ceiling at Dewan Serbaguna, Univeristi Sains Malaysia,
Engineering Campus which then the velocity of pedestrians was determined by tracking
their trajectories. The result includes the walking speed by gender, and the effect of the
corner on the behaviour of the pedestrians and their approaching speeds. It was found
that that average walking speed of female, is higher than average walking speed of
male. It was observed that pedestrian tend to walk closer to the inner corner and the
pedestrian to reduce their speed when approaching the corner. The results are of
particular importance for designing the structure especially walking at walkway and
also beneficial for the design of an emergency response plan.
