Planning for large crowds can be an extremely complex process. Mistakes can be costly not only financially, but through effects to people, property and infrastructure, as well as damage to reputation for both public sector and private sector organizations. Comprehensive preparation is often more effective though the use of computer-based simulation.

CrowdFlow from Avalias provides advanced analysis and visualization when a more detailed view is required for planning and assessment purposes. With Avalias CrowdFlow, your organization can be better prepared for emergency situations during major events, and even day-to-day operations.

Improve crowd safety through detailed planning

Advanced micro-simulation and visualization environment

Suitable for pedestrian modeling, crowd analysis and design evaluation, CrowdFlow allows you to see the effects of modifications to your plans, particulary important where last-minute planning changes may have an impact on crowd safety.

Evaluate the efficiency and safety of plans

Run and re-run CrowdFlow simulations to identify problems related to increased demand. Run sensitivity tests with worst-case demand figures to ensure that safety won’t be compromized in the event of an emergency.

Communicate your crowd management plans with ease

CrowdFlow can give you the edge in communicating your plans to decision makers and other stakeholders. Make the move from macro-simulation models to micro-simulation visualizations.

Take action. Be better prepared.

Features

  • Flexible and configurable behavioral parameters

    Change physical and behavioral attributes of individuals within a crowd. Modify their agility, mood levels, age, size, aggression, politeness, impatience and intentions of each individual within the crowd, either directly or by percentage distribution. For example, you can easily observe the difference between a drunken sports crowd, a peaceful protesting crowd, a crowd running a marathon course, and a crowd panicking during an evacuation.

  • Multiple presentation options

    CrowdFlow can output video of crowd behavior both as a 2D aerial view, or as a 3D projections from any angle.

  • Artificial intelligence on a massive scale

    CrowdFlow uses Avalias' proprietary artificial intelligence techniques to allow the intentions and behaviors of each individual to be calculated, across tens of thousands of simulated people.

  • How it works

    Our experienced team of specialists work closely with your planners to gather the input data required for the micro-simulation. This will include factors such as forecasted crowd quantities, group mood, event style, and planned barrier configuration. We then rapidly create a Crowdflow model of the environment based on CAD models or aerial photography when working with larger areas. Working closely with your planners, we fine-tune the plans and deliver visualizations in the video format of your choice.

FAQs

What information does CrowdFlow™ require to do its simulations?

CrowdFlow™ takes terrain information (i.e. maps of the area you are expecting people to occupy) along with details of the various places that people are coming from and where they are going to. It also allows you to specify aspects of crowd or individual personalities that combined can influence the overall behavior of the crowd. These attributes include aggression levels, desired walking speed, politeness levels, fear levels, personal comfort space, person size, levels of urgency / panic. This information is all determined by Avalias in discussions with you.

How do I know what all the crowd behavior attributes should be?

Generally, you don't have to worry about the detailed specifics of crowd behavior. Instead, you merely choose one of our pre-defined crowd types (e.g. Peaceful Slow Walking Crowd, Aggressive Sports Audience, General Train Station Crowd, Busy Airport Crowd) and this automatically uses appropriate values for the more complicated factors of crowd behavior. All you then need to do is provide the maps of the area, details of entry and exit points, and the quantity of people expected. For transport scenarios some additional data is necessary e.g. timetables of asset movements.

What is the output of CrowdFlow™?

CrowdFlow™ uses the crowd data gathered as described in the questions above to produce video footage containing a visual simulation of the crowd at any given time within an event or situation. Using this, you can see what the crowd's movements may be 10 minutes or 2 hours into an event. The videos can either be produced as 2D aerial views of the area being watched, or as 3D angled views on certain points of interest. Typically, the aerial views are most useful for planning and mitigation, and the 3D angled views are excellent for demonstration and visualization.

Can I build my own crowd simulations in CrowdFlow™?

Currently, CrowdFlow™ is offered as a service. Avalias will assist you in gathering the information needed to put together a useful crowd model, and then will provide you with finished video files in the media format of your choice.
