Pedestrian modelling

People and crowd modelling

Pedestrian simulation considers how pedestrians move, react and respond to the built environment, in order to create safe and efficient environments with minimum redesign.

Using PTV Viswalk, an advanced simulation software based on mathematical models, we can study the impact of proposed changes to indoor and outdoor spaces before a design is built or implemented. We will identify potential bottlenecks or under performance in particular areas and determine the impact of alternative design options. This is especially useful in situations with a high pedestrian flow where the assessment of capacity aims will ensure the optimum use of the available space.

We apply the pedestrian modelling analysis in the design of pedestrian spaces and facilities, including for urban and construction planning, crowd control scenarios, event management scenarios, pedestrian safety planning, vacuation measures, and numerous other applications aimed at ensuring a smooth flow of pedestrians.

Pedestrian modelling assesses people’s movement and walking behaviour in public spaces, buildings and infrastructure. It is aimed at understanding the opportunities and constraints in providing an optimised walking environment, either internal or external to a building. Cundall utilises pedestrian modelling to ensure people’s convenience, comfort, safety and security within every design.

Facility planning

The capacity of a venue (i.e. office, station, airport) or space depends on the available space for people. Using pedestrian modelling we can:

• Analyse capacity and use space efficiently.

• Avoid bottlenecks and remove possible spatial barriers when planning new developments.

• Assess if existing structures pose a hazard to pedestrian movements and if they can, make sure they can withstand additional number of people.

• Compare alternative planning variants before implementation.

• Assess vertical movements between different floor levels, through simulation of ramps, stairs, lifts, moving walkways, etc.

Event planning

When designing for events, it is important to analyse the crowd interaction inside and outside of the infrastructure, or any possible situations in order to:

• Simulate spill-out after the end of an event, possibly towards public transport infrastructures such as trains or buses.

• Simulate ingress to an event.

• Simulate circulation at an event (e.g. half-time break dynamics in a stadium).

• Visualise the flow of pedestrians based on simulation results.

• Realistic routing to show where facilities such as shops, bathrooms and escape routes can be placed in an optimal way.

• Evaluate capacities and security procedures taking cognisance of delays.

Evacuation and safety analysis

Crowd safety is of paramount concern, especially in public places. Through pedestrian modelling we can assist in reviewing numerous structural and organisational measures aimed to reduce and control the unmanageable behaviour of people in emergency situations. We can:

• Analyse potential danger, plan ingress and egress flow in buildings, stadiums and other facilities to ensure safe crowd exits.

• Model escape routes and evacuation scenarios in high-rise buildings when considering emergency scenarios, such as fire or security emergencies. We work closely with our Fire Engineering team, using pedestrian modelling to test emergency evacuation procedures.

Pedestrians and traffic

Alongside simulating pedestrians, Cundall can integrate this service with the simulation of all transport modes to provide an overall assessment of indoor and outdoor spaces. We can model the interaction of all modes, including public transport simulation, simulation of cyclists and pedestrians to review the overall operation of a localised area or wider transport network.

3D visualisation

The video-format output of our microsimulation service allows demonstrating the benefits of a design with data visualisation. This is particularly helpful for communications with a non-technical audience, for example at public exhibitions, committee meetings and public inquiries, as the results can be visually demonstrated in real or shortened time through a realistic and comprehensive representation of the simulation in 3D, rather than just displaying results through use of graphs and tables.
