We wrote a new article on urban traffic simulation, with an additional angle of simulating emergency or crisis situations, in the Journal of Nonlinear Systems and Applications (JNSA). It's so far probably the best article on what we did, less detailed but more synthetic than the ones in ICCSA. We describe how we build a graph then a trafic network from shapefiles, so as to have a geographically correct simulation. We explain the way we modeled each car with an agent, with a quite sophisticated behavior, reactive when everything is fine, switching to more cognitive when it's not. Despite the details, it runs faster than real time on a real urban agglomeration, with tens of thousand of vehicles. We finally describe the new family of tactics aimed at modeling the behavior of drivers in times of crises.
