PTV Vissim- Simple Signal Controller

PTV Academy PTVTalks Tooltips

Simple Signal Controllers were released in PTV Vissim 2020 to allow simple, built-in traffic-dependent controls to be created. Each controller contains a Default Signal Group for the major flow and a Calling Signal Group for the minor flow. This ToolTip video describes the setup required for each of these controllers: Two-Stage Controller Railway Crossing Pedestrian Crossing Watch the recording below:

DTA

PTV Vissim- Dynamic Traffic Assignment Series

PTV Academy PTVTalks Tooltips

Dynamic Traffic Assignment (DTA) is the process of generating route flows based on an origin-to-destination (OD) demand model.  The user defines the origins (demand sources), destinations (demand attractions), and the number of trips between these locations.  Vissim then assigns the demand that travels on each path from the origin to the destination.  Dynamic Assignment is an iterative process in that ...
