Aimsun Next transport modelling software
Aimsun Next is an all-in-one transport modelling platform, providing a single, united network representation of how people move in any mode, on any scale.
Aimsun Next: the unified platform for all levels of transport modelling
Aimsun Next brings together every scale of transport modelling in a single, powerful software platform. Simulate and analyse everything from individual pedestrians, cyclists, and vehicles with non-lane-based behaviour (microscopic), to city-wide traffic flows (macroscopic), and everything in between—including mesoscopic and hybrid schemes.
Enhance your workflows with Python scripting, APIs, and software toolkits, and connect seamlessly to external systems whenever your projects require.
Aimsun Next is not just a standalone tool—it’s your gateway to broader possibilities, collaborative projects, and advanced approaches to achieving your transport modelling objectives.

Why should I choose Aimsun Next over other software packages?
Efficiency
Modeling sustainability
Aimsun Next now features six integrated environmental models, including the new COPERT emission model. The Battery Consumption Model assesses electric vehicle energy use, while all models have been streamlined to support every engine type and work seamlessly together. The suite now comprises four emissions models—QUARTET, Panis et al., the London Emission Model (LEM), and COPERT—and two energy models: the Fuel Consumption Model and the Battery Consumption Model.
With growing climate concerns, transit and non-motorised modes are increasingly important. Aimsun Next offers flexible traffic management for transit detours and continues to refine models for bicycles and non-motorised vehicles, introducing new reactive parameters for more realistic simulation
True integration
Aimsun Next uniquely integrates all traffic and pedestrian models—at every level of detail—within a single platform. This unique capability makes it easy to combine strategic and operational tasks, with seamless data exchange. For example, you can effortlessly transfer path-assignment results from a macroscopic to a microscopic model. Multi-layered flexibility has never been simpler.
Large-scale models
Aimsun Next is perfect for large-scale modeling tasks, and is especially user friendly for working with traffic demand, transit assignments, splitting and joining zones, creating more accurate ‘warm-up’ traffic states, and providing customizable analytical outputs.
Intuitive model builds
Flexibility and accuracy
Combine different types of paths, generated with different algorithms, to simulate more representative behavior and to analyze non-recurrent conditions like scheduled events and incidents.
Meet tight project deadlines
Split and share a project among colleagues by using model revisions: one modeler can work on the meso area, another modeler can work on the micro subnetwork, and a third modeler can work on signal controls. All their revisions can be compared, saved separately, and merged back into the main project file by the lead modeler. This method can reduce model-building time and it means that you can run different studies in parallel rather than sequentially.
Extensible and cooperative
Non-lane-based modelling
Aimsun Next has a built-in pedestrian simulator and can handle the movement of motorbikes, bicycles, rickshaws, and all vehicle types that tend toward non-lane-based behaviour.
Integrated signal simulation
Efficiency
Simulate different traffic strategies using one model, geometrical alternatives, different demands, different transit arrangements, and a broad range of strategies, policies, and triggers that react to time or network conditions.
Modeling sustainability
Climate concerns also mean a crucial role for transit systems and non-motorized vehicles. Aimsun Next has flexible traffic management strategies for transit-route detours, and we continue to fine-tune our models for bikes and non-motorized vehicles with new, reactive parameters for more realistic behavior.

Intuitive model builds
Vehicle conflicts are generated automatically, based on the geometry of the network. Performance and behavior parameters are stored within roads, lanes, and vehicle types, which allows for consistency across the board as well as discrete ‘surgical’ changes wherever needed. These parameters can be stored in a template for your team or organization to use.

Meet tight project deadlines
Extensible and cooperative
Aimsun Next incorporates Python scripts, APIs, software toolkits, working links with external traffic systems, autonomous vehicle environments, and compatibility with the formats of all relevant programs in the field.
Non-lane-based modeling
Aimsun Next has a built-in pedestrian simulator and can also handle the movement of motorbikes, bicycles, rickshaws, and all vehicle types that tend toward non-lane-based behavior.
