“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.

Side-lane merging in an Aimsun Next mesoscopic model

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.

Reversible lanes and alternating one-way lanes

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

MFC and Battery Consumption Model

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.

Transit Route Change traffic management action

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.

C/ACC controller in Aimsun Next

October 2021: In this article, Martin Hartmann explains and demonstrates Aimsun Next microsimulation of vehicles equipped with cooperative adaptive cruise control (CACC).

How to generate throughput and demand outputs

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.

Importing GTFS data into your Aimsun Next network

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.

Switching to Python 3

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

Generating Control Plans from Volumes

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.

Scripting with time series

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.
