Table View – review of all functionalities

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.

Select link analysis for schemes

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.

Creating accessibility maps with Aimsun Next

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.

Using space-time diagrams for calibration

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.

Random seeds in transport models

This technical note will explain the different sources of stochasticity within micro and meso experiments in Aimsun Next and how you can control them.

Low Emission Zones: assessing their environmental impact

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.

My model is in the Atlantic Ocean

“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.
