Dynamic matrix estimation in PTV Visum
This webinar demonstrates the dynamic matrix estimation for timetable based public transport assignment in PTV Visum.
📺 Ep. 07 – PTV SBA video series 🤔: How to calibrate demand
Learn about adding dynamic count data to the model, Creating user-defined attributes for evaluating results, converting demand time series • Setting up dynamic OD matrix estimation (DODME) procedure, and more.
Learn about the display of dynamic link results (volumes, speeds, densities, queues), display of node results (delays), viewing these results in lists, and evaluating journey times.
Learn about SBA visualization, assignment statistics and convergence, path lists and evaluation of paths, graphical procedures like flow bundle (aka link analysis), and dynamic shortest path evaluation.
📺 Ep. 02 – PTV SBA video series 🤔: How to code the network
Learn about basic coding requirements (links, transport systems, turns), visualization in the network and viewing data in lists as well as coding junctions (control type, gap acceptance parameters, signal times, daily plans).
📺 Ep. 04 – PTV SBA video series 🤔: How to set the procedure
Learn about creating groups and procedures in the procedure sequence, settings parameters for the simulation-based assignment (SBA), and troubleshooting errors.
