PTV Visum - Creating a 4-Step Transport Model (TR-T0109)
Expand your knowledge of demand modelling
One of the main uses of Visum is modeling transport demand. The most common travel forecasts analyse the daily travel behaviour of people. These forecasts provide answers to the questions, when, how often, where and how do people travel.
The standard 4-step model generally includes the steps trip generation, trip distribution, mode choice, and assignment. In Visum the variants 4-step model with sequential calculation and Nested demand model can be used. The two variants have in common that both trip generation and assignment are carried out in separate steps, either before or after calculation of the demand matrices.
This two-day course will first introduce you to the various modelling methods. After describing all demand models available in PTV Visum, the course covers in detail the subjects of model segmentation, data supply, calibration and validation. The actual implementation of these subjects in PTV Visum is explained and participants practice with a training model.
The course provides an introduction to demand modelling, but is also aimed at users who already have experience with macroscopic traffic models and want to deepen their knowledge.
You successfully participated in our basic course "PTV Visum - Introduction to Macroscopic Network Modelling" (TR-T0101) or have similar experience with PTV Visum. You also have obtained practical project experience.
It is of advantage if you attended our course "PTV Visum - Introduction to Public Transport Modelling" (TR-T0102) and have some basic knowledge of demand modelling.
