Pedestrian Dynamics Simulation Software

See the crowd
before it gathers.

Optimal Crowd simulates where crowds build up, where bottlenecks form, and how long an evacuation could take — so you can explore your space before anyone sets foot in it.

Crowd safety is a growing concern.
The tools to plan for it should keep pace.

As crowds gather more often and at greater scale, the stakes keep rising. Meeting them calls for tools that are powerful, scientifically sound, and accessible — for the venue managers, architects, and safety officers who need answers, as well as the specialists who model the space. That's what Optimal Crowd is built to be.

People don't just follow the shortest path.
They read the crowd.

People take the shortest path — until it looks crowded. Optimal Crowd captures that: crowd density shapes each route choice, and those choices reshape the density.

"If the short path is packed, I'll take the longer one — and so does everyone else."

That mutual anticipation is exactly what Optimal Crowd models. Inspired by mean-field game theory, it settles the crowd into a Nash-equilibrium-inspired balance — a distribution where no one gains by switching routes, with no manual assignments and no oscillations.

  • Density-informed route choice

    The busier a path gets, the less attractive it becomes — no manual configuration.

  • Smart crowd-splitting

    When routes branch, the engine spreads people across them so no single path overloads.

  • Predictive rerouting

    People reroute based on where congestion will be — so bottlenecks are avoided before they form.

Run faster.
Compare in parallel.

On local hardware, one complex simulation can take hours, and comparing a handful of layouts can mean days of sequential runs. Optimal Crowd is cloud-native — no installs, no hardware constraints, no waiting in line.

Parallel scenarios

Launch many variants at once and compare them side by side.

Large-scale crowds

Simulate large crowds without the hardware limits of a local machine.

Fast results

Results in a fraction of the time a sequential local run takes.

Scales on demand

Cloud resources match the scenario, so there's no capacity planning.

Runs in any browser

No install, no IT ticket — any device.

Live progress

Watch density and flow build as the simulation streams.

For the decision-maker
and the specialist alike.

Crowd simulation has usually meant handing the problem to a specialist and waiting weeks for a report. Optimal Crowd changes that: the same tool serves the expert modelling the space and the manager, architect, or safety officer who has to act on the result.

Event Venues

Validate entry and exit strategies before opening day. Spot queue bottlenecks and stress-test emergency scenarios.
