Hybrid Simulation
February 2018: Geline Canayon and Laura Torres give you a brief guided tour through the how, when, where and why of hybrid simulation.
Distribution and Modal Split Functions
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.

The Grouping Category Tool (Part 2): Screenlines
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.
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.
