TR-T0130 PTV Visum – Hybrid Macro-Meso Highway Assignment with SBA

Short Description

Realistic modelling for nodes requires them to be modelled such that conflicts between turns can be identified correctly. In the Visum context, this means that the geometry and relevant control needs to be modelled in the junction editor. With this detail in place, Intersection Capacity Analysis (ICA) and mesoscopic simulation with SBA are possible.

Simulation-based dynamic assignment (SBA) is a dynamic assignment procedure which loads demand using the simplified car-following simulation. The procedure is suited for medium-sized and large networks whose network model and demand are suitably modelled for dynamic applications.

A recent development has been to allow for hybrid macro-meso assignment with SBA. This capability allows the possibility to create large-scale dynamic models with the flexibility to require the additional junction (node) detail only where the mesoscopic simulation is used. 

Over the course of the training, you will learn the principles of hybrid macro-meso highway assignment with SBA and create a model from the first principles. You will also use an existing large-scale model to test and compare a before-and-after scheme using this methodology. 
 

Course Level

Advanced

Target Group

Transport modellers familiar with highway assignment or microsimulation who are interested in how mesoscopic modelling can improve their workflows, and/or how hybrid macro-meso modelling can be applied at scale. It is aimed at users who already have basic knowledge of PTV Visum and who are familiar with the principles of highway assignment model.

Prerequisites

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 gained some practical project experience in highway assignment modelling.
