New tool: Visum -> BusMezzo network importer!

Network coding is a crucial and often time consuming preparation step when working with transport simulation and assignment models.

Rafał Kucharski and Arkadiusz Drabicki from Politechnika Krakowska have developed a tool for importing networks from Visum (PTV product) to BusMezzo.

The tool is available on Github, see the for important notes on how to use it: Network importer on Github

Note that since Visum allows importing networks from GTFS, you can convert GTFS networks to BM networks via Visum. Of course, you may be interested in specifying  additional input, depending on the application.

ITS Berkeley seminar announcement

Seminar abstract: The metropolitan passenger transport landscape is shifting due to a combination of technological and social developments which enable both service providers and service users to become increasingly adaptive. Service providers can manage their resources to better cater for prevailing demand patterns, while service users can adjust their behaviour in response to real-time information. In this seminar, I will present our work on modelling system dynamics and the interaction between supply and demand under uncertainty in relation to tactical planning (e.g. fleet size and composition, frequency setting) and real-time management (e.g. trip dispatcher, disruption management) of fixed line-based as well as flexible on-demand services.

Recovery time and propagation effects of passenger transport disruptions

How do disruptions propagate in public transport networks? for how long and how far away from the source are passengers affected?

In a new paper on Physica A: Statistical Mechanics and its Applications, we propose a method for quantifying the extent to which the network exhibits spillover effect.

Model results are evaluated for the Stockholm network using a dynamic non-equilibrium assignment model.
