The
understanding of crowd behaviour in semi-confined spaces is an important part
of the design of new pedestrian facilities, for major layout modifications to
existing areas and for the daily management of sites-subject to crowd traffic.
Conventional manual measurement techniques are not suitable for comprehensive
data collection of patterns of site occupation and movement. Real-time
monitoring is tedious and tiring, but safety-critical. This paper presents some
image processing techniques being developed at King's College London which,
using existing closed-circuit television systems, can support both data
collection and on-line monitoring of crowds. The application of these methods
could lead to a better understanding of crowd behaviour, improved design of the
built environment and increased pedestrian safety
