Traffic management actions in Aimsun
Extendibility: scripts, APIs and cost functions
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.
June 2022: Aimsun Next has a specific mesoscopic merging behavior model that is controlled by the cooperation gap and merging gap parameters. Mohammad Saifuzzaman explains how to use these parameters to control merging behavior and match observed traffic flow and congestion.
May, 2022: In transport networks, the available infrastructure may vary through the day. In this technical note we will review how to close lanes temporarily in one direction so that the other direction can use them
April 2022: The new Microscopic Free-flow aCceleration (MFC) and Battery Consumption Models allow for a more accurate fuel and energy consumption analysis. This technical note walks you through the details of the models and how each parameter affects the vehicle behavior.
March 2022: A new feature introduced in Next 22 is the Transit Route Change traffic management action. This technical note will go over how to implement the action and ways in which it could be used.
February 2022: The SCATS traffic control system is designed to optimise traffic ﬂow. Dimitris Triantafyllos explains how the SCATS ITS Interface can import data from SCATS ITS into the Aimsun Next network.
December 2021: The Aimsun Next API is a collection of functions, in Python or C++, that allow users to read information and perform actions during the mesoscopic, microscopic or hybrid mesoscopic-microscopic simulation.
November 2021: Geline Canayon explains a new feature that makes it much easier to adapt zone plans as you develop your model.
October 2021: In this article, Martin Hartmann explains and demonstrates Aimsun Next microsimulation of vehicles equipped with cooperative adaptive cruise control (CACC).
September 2021: In traffic modelling, it can be useful to compare the traffic demand and the throughput along a route: how many people would like to make a journey and how many were able to carry out that journey within a set time frame.
July 2021: GTFS feeds enable transit or public transport agencies to publish their data, and developers to write applications that use this data in an interoperable way. Dimitris Triantafyllos explores how to import this GTFS data into an Aimsun Next model.
June 2021: Geline Canayon guides you through adding a Web Map Service (WMS) or Web Map Tile Service (WMTS) server link to add background aerial images to your model.
May 2021: Python 2 reached end-of-life status in January 2020. Tessa Hayman gives you some tips on getting your script Python 3-ready for optimum performance in Aimsun Next
April 2021: What do you do when control plan data is not available? You might face this problem when working with future scenarios that have not been fully detailed, or on a first approach from macroscopic to dynamic. Our product specialist, Marga Delgado, has the answer.
March 2021: Tessa Hayman guides you through the complexity of handling time series via Python scripting and explains how to create your custom time series in a way that can be visualized in the UI.
February 2021: Did you know that an Aimsun Next junction (node) can be linked to an external controller, such as the Siemens UTC System with SCOOT?
