Event Crowd Flow and Queue Simulator

Simulate queues and waiting times at entrances and exits to find bottlenecks and improve attendee flow at your event.

Event inputs
Check-in
Catering / Lunch

Assumes 80% of attendees use catering within the 90-minute window.

Exit / Outflow

Estimated outflow window: 30 minutes after the end of the event.

Critical flows - action needed

Event with 500 attendees, lasting 8 hours.

Operational recommendations

  • Critical phase detected in: Check-in, Catering, Exit. Increase the service points right away.
  • Give attendees staggered times to reduce peaks.

How we read your data for the suggestions: each checkpoint counts as a risk, with a likelihood of 5 out of 5 if the queue is critical, 3 if it needs watching and 1 otherwise, and an impact of 1 point for every 5 minutes of waiting, up to 5.

How it works

Enter the venue layout, entrances and exits, number of attendees and arrival/departure profile to simulate how people move through the space. The simulator identifies bottlenecks and suggests improvements to cut waiting times and keep check-in and exit safe.

Frequently asked questions

How do you manage crowd flow at a large event?

Identify the pinch points (entrances, exits, toilets, catering areas), spread arrivals over time with staggered schedules, signpost routes clearly and place staff at the main junctions to handle traffic peaks.

How many exits does an event need?

The minimum number and width of exits are set by fire and safety regulations and depend on capacity and venue type. Venues open to the public generally require at least two independent exits, with total exit width sized to the maximum occupancy: the exact values for your venue must be checked with a qualified professional. For outdoor events, always follow the safety plan approved by the competent authorities.

How do you reduce queues at event entrances?

Use pre-registered badges with QR codes to speed up check-in, open the doors 60-90 minutes early, add check-in points for large events (as a guide, 1 for every 200 people per hour) and encourage staggered arrival with targeted messages.
