June 2019: In Part 2 of this GIS pro tip, Geline Canayon explains network importer settings for GIS files.
May 2019: In Part 1 of this series, Geline Canayon explains GIS file preparation and basic importer settings. Part 2 will deal with network importer settings.
February 2019: Mohammad Saifuzzaman explores the use of adjustment weighting functions to improve the GEH and not just the R2.
May 2018: Laura Oriol shares her tips for altering parameters for throughput at traffic signals and at major-minor priority junctions.
April 2018: in the first of a two-part series, Laura Oriol shares some tips on how to push meso calibration to the max and speed up your workflow.
March 2018: Mauricio Castro and Gabriel Funes take you beyond the default settings for Stop Lines and show you how to control where vehicles stop with greater precision.
February 2018: Geline Canayon and Laura Torres give you a brief guided tour through the how, when, where and why of hybrid simulation.
January 2018: Margarida Delgado explains how the Distribution and Modal Split steps are now split into two separate processes to give you greater flexibility when choosing which model to work with, and to give you more control at each step.
August 2017: Want to update your strategic model zoning system to organise the ever-increasing amount of data available? Dimitris Triantafyllos and Paolo Rinelli show you how to split zones to better represent the entrance and exit of the traffic volumes in the network.
June 2017: Dimitris Triantafyllos and Carles Illera explain how to use a Turning Penalty Function that can perceive costs from a control plan, and how to model stop/yield signs in macro using Junction Delay Functions.
May 2017: Dimitris Triantafyllos and Sergi Pujadas explain how to alleviate traffic congestion using a variety of traffic management actions.
April 2017: Laura Torres, Sergi Pujadas and Emmanuel Bert explain the nuts and bolts of how to get your Aimsun videos looking sharp and running smoothly.
March 2017: Marga Delgado shows you how to use Contents to group matrices into subfolders, which is particularly convenient when working with multiple matrices.
February 2017: Sara Pardo shows you how to customize the order of your objects for clearer and more semantic organisation.
January 2017: Paolo Rinelli and Dimitris Triantafyllos explain a technique for modelling connected vehicles using Aimsun API: Cooperative Adaptive Cruise Control.
December 2016: Maud Chassat describes how Aimsun’s attribute overrides can be extremely useful for modifying attributes of existing objects.
November 2016: Tamara Djukic explains how to use groupings of sections or detectors to define screenlines – a great technique for more efficient OD demand adjustment and validation.
October 2016: Tamara Djukic explains how the Grouping Category tool can speed up and improve the way you apply traffic data to calibration and validation of traffic models or simulation input and output data processing. With additional input from Timothy Lim and Phoebe Ho.
September 2016: A low number of iterations dramatically decreases the total computation time to run a DUE – Josep Perarnau shows you how to cut initialization time in half by using a subset instead of the full path assignment result file.
August 2016: Most users are familiar with creating their own attributes within objects within an Aimsun model. Grant MacKinnon explains how you can also add a column to an object where a value is returned based on some Python Code, allowing you to calculate a value on the fly.
