Readers might know that we like pedestrian models here. So in keeping with the theme of NetLogo models and the use of GIS below are two simple pedestrian models. In the first model (shown in the movie below), agents just exit the room, taking the shortest path (calculated via a cost surface). The idea behind this first model is to highlight how changing the width of the exit (i.e. the door) can impact on the evacuation time (the model can be downloaded from here).
In the second model (shown in the movie below and the code is here) we show a more complicated configuration based on a floor plan that has been first converted from a CAD file to a Shapefile before being converted into a raster where each cell is 50cm by 50cm that can then be used in the NetLogo model (coming soon there will be a bunch of tutorials on how we do this).
In this model, agents like in the simple model above, walk to the exit. In essence, one could consider this as a fire evacuation scenario. The agents are assumed to walk to the nearest exit, analogous to following exit signage. Similar to the first example, user can explore what happens if an additional exit is added.
More information about the models (and the code) can be found over at Geospatial Computational Social Science.
