When simulating non-trivial scenarios of pedestrian movements it is necessary to model boththe small-scale movements to a visible target (operational level) and the process to find and select routesleading to a possibly non-visible destination (tactical level). A huge number of different approaches modellingthe operational level of pedestrian movements are already proposed. However, the majority of models of thetactical level are still restricted to shortest path algorithms or similar algorithms determining minimal travelefforts. These approaches assume that pedestrians have unrestricted knowledge about the spatial structureof buildings or facilities and are able to assess lengths and travel times of all possible routes. In fact, inreality the knowledge degree of people differs widely. In addition, wayfinding is a complex process includingvarious tools and strategies which are represented only roughly by minimum-effort calculations. To improvethe situation we present modelling approaches representing tools and strategies of human wayfinding anddecision making based on evidence from psychological studies and literature. Furthermore, an approach hasbeen created to consider perception in addition to decision making to model wayfinding. In particular, weanalyse the consequences and differences appearing in the simulation of complex scenarios when consideringmore elaborated wayfinding procedures instead of using classic minimum effort calculations. To quantifythe consequences and differences we particularly investigate resulting evacuation times. For this purpose weutilize the results of evacuation simulations taken place in the National Gallery of Arts in Washington, D.C..Comparing the results of simulations considering wayfinding approaches and shortest path calculations wediscuss pros and cons, limits, possibilities and the importance of perception and wayfinding models. |
