Extendibility: scripts and APIs
Visualizing data
Importing data
Working efficiently
Strategic modeling
September 2025: The Revisions feature in Aimsun Next allows a team of modellers to work within a single file, boosting efficiency, speed and accuracy.
Marga Delgado explains how a good data comparison tool is the foundation of our ability to evaluate and analyze differences between simulation results and therefore, make strong, well-supported decisions about transportation network design and management.
Lua is a lightweight scripting language that allows users to write custom cost functions while also enabling faster run times for complex models. In this month’s technical note, Tessa Hayman explains how Lua differs from Python and the benefits it can bring to your Aimsun Next models.
Paolo Rinelli explains how our new customer portal and subscription-based licensing bring Aimsun Next users great benefits in terms of administrative efficiency, remote desktop, cloud computing and security.
How do we decide whether to walk somewhere or take the bus and how do you model that decision in Aimsun Next?
Tessa Hayman explains how to analyze route choice changes between schemes tested using microscopic, mesoscopic and hybrid network loading.
Marga Delgado explains how the the Path Assignment Plan feature in Aimsun Next gives you unparalleled flexibility in reusing previously calculated paths.
Marga Delgado explains how the Table View in Aimsun Next is a powerful tool that can boost efficiency across all stages of a modelling project: when editing, when calibrating and when reviewing the final results.
Tessa Hayman explains that when appraising schemes, it can be useful to understand how different schemes may interact with each other. This can help you understand any potential synergy between schemes and identify a subset of scenarios to test with fully detailed modelling.
Tessa Hayman explains how you can use the new functionalities in Aimsun Next 23 to create outputs for monitoring changes during matrix development as outlined in the UK’s Transport Appraisal Guidance (TAG).
How to apply a custom Route Choice function to emulate a heavy truck guidance system.
Marga Delgado explains how to use the Isochrones tool in Aimsun Next to generate accessibility maps for different transportation modes and different criteria as distance or travel time and how accessibility maps can help assess the impact of new roads or transit services.
Dimitris Triantafyllos explains how to create speed contour plots in Aimsun Next to show the time, location, and subsequent propagation and dispersal of congestion on the highway.
February 2023: Tessa Hayman explains different options for multiple centroid connections and the effects of different parameters and assignment algorithms.
This technical note will explain the different sources of stochasticity within micro and meso experiments in Aimsun Next and how you can control them.
Simulation is an invaluable tool for supporting the definition of effective emissions policies. Aimsun helps you compare the effectiveness of different measures and assess related impacts, so you can keep pollution within legal thresholds without compromising on mobility.
Mohammad Saifuzzaman shows how the Aimsun Real Data Set Checker makes it quicker and easier to create clean datasets and examines some different use cases.
Dimitris Triantafyllos explains how to run a micro or meso simulation in Aimsun Next connected to SCATSim, a suite of software modules designed to emulate the SCATS adaptive traffic control system.
“My model is in the Atlantic Ocean!”
Tessa Hayman guides you on how to set the coordinate reference system correctly in your Aimsun Next model.
Dimitris Triantafyllos explains how to use the Aimsun Next project folder structure to automatically manage model files.
