The Grouping Category Tool (Part 1): How to access model input and output data efficiently
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.
DTA: Speed up your DUE convergence
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.
Python: from function to attribute
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.
