Hybrid fish-plankton model

Gudrun Wallentin Christian Neuwirth | Published Fri Oct 28 17:54:17 2016 | Last modified Sun Jan 29 07:32:14 2017

A hybrid predator-prey model of fish and plankton that switches dynamically between ABM and SD representations. It contains 6 related structural designs of the same model.

Bicycle encounter model

Gudrun Wallentin | Published Sat Oct 29 20:45:47 2016 | Last modified Fri Mar 29 19:38:22 2019

This Bicycle encounter model builds on the Salzburg Bicycle model (Wallentin & Loidl, 2015). It simulates cyclist flows and encounters, which are locations of potential accidents between cyclists.

Salzburg Bicycle model

An ABM to simulate the spatio-temporal distribution of cyclists across the road network of the city of Salzburg.

The purpose of the model is to generate the spatio-temporal distribution of bicycle traffic flows at a regional scale level. Disaggregated results are computed for each network segment with the minute time step. The human decision-making is governed by probabilistic rules derived from the mobility survey.

COVID-19 ABM

Gudrun Wallentin | Published Tue Apr 21 07:20:07 2020 | Last modified Tue Apr 21 08:59:02 2020

Model of the Corona pandemic outbreak

The COVID-19 ABM aims to predict the qualitative behaviour of the CoViD-19 epidemic dynamics for the greater region of Salzburg City. Specifically, by means of scenario testing, it aims to help assessing how containment interventions can allow a stepwise relaxation of the lockdown without risking a new outbreak.

Homing pigeon model

Gudrun Wallentin | Published Sat Oct 29 18:35:49 2016

This model represents the flight paths of a flock of homing pigeons according to their flocking-, orientation- and leadership behaviour.

In this model, we simulate the navigation behavior of homing pigeons. Specifically we use genetic algorithms to optimize the navigation and flocking parameters of pigeon agents.

TREELIM

Gudrun Wallentin | Published Wed Nov 30 13:52:16 2016 | Last modified Tue Jan 10 14:43:13 2017

The model simulates the spatial patterns of secondary forest succession above the current alpine tree line in the context of land use and climate change. Three scenarios are offered: (1) climate change, (2) land use change, (3) species composition.
