Notting Hill Carnival - London
A two-day Caribbean street carnival in west London drawing enormous crowds into narrow streets around static sound systems — a classic recipe for dangerous density at pinch points.
Why the crowd presents risks
- •Narrow residential streets become chokepoints when crowds pack toward sound systems.
- •Very high footfall over a sustained period, with alcohol throughout.
- •Crossing flows of dense crowds through the same tight routes.
Critical Bottleneck Locations
Crowds pack toward the music and stop moving — density spikes against buildings.
Crossing flows meet with no room to pass, creating pinch points.
Working this event?
Stewards and volunteers at events of this scale benefit from basic crowd safety training — learning density thresholds, route clearance, and emergency protocols.
These are our own event profiles, compiled from public information. We are not affiliated with, nor do we endorse, these events. Attendance figures are planning estimates, and the recommended number of trained crowd-safety volunteers is a rough guide based on common steward ratios — not an official figure or a legal requirement.
