“…Previous work has established that the likelihood of pedestrians to choose particular routes is influenced by static information, such as the length of the route and the presence of stairs or escalators [ 5 , 11 ]. There is also limited empirical evidence suggesting that pedestrians take the movement of others into account when choosing routes [ 12 , 13 ]. However, to date there is no detailed understanding of the dynamic, time-dependent route choice mechanisms in humans.…”

We conducted a computer-based experiment with over 450 human participants and used a Bayesian model selection approach to explore dynamic exit route choice mechanisms of individuals in simulated crowd evacuations. In contrast to previous work, we explicitly explore the use of time-dependent and time-independent information in decision-making. Our findings suggest that participants tended to base their exit choices on time-dependent information, such as differences in queue lengths and queue speeds at exits rather than on time-independent information, such as differences in exit widths or exit route length. We found weak support for similar decision-making mechanisms under a stress-inducing experimental treatment. However, under this treatment participants were less able or willing to adjust their original exit choice in the course of the evacuation. Our experiment is not a direct test of behaviour in real evacuations, but it does highlight the role different types of information and stress play in real human decision-making in a virtual environment. Our findings may be useful in identifying topics for future study on real human crowd movements or for developing more realistic agent-based simulations.

“…At one end of a spectrum of simulated environments are 'table-top' pen and paperscenarios developed to assess decision-making of miners, fire-fighters or military personnel in emergencies that can subsequently be used for training purposes [19]. At the other end of the spectrum for simulated environments are fully immersive scenarios for pedestrians that promise to be useful in calibrating models for pedestrian movement and in exposing volunteers to fully controlled emergency situations [20]. We opted for an intermediate level of simulation sophistication.…”

The evacuation of crowds from buildings or vehicles is one example that highlights the importance of understanding how individual-level interactions and decision-making combine and lead to the overall behaviour of crowds. In particular, to make evacuations safer, we need to understand how individuals make movement decisions in crowds. Here, we present an evacuation experiment with over 500 participants testing individual behaviour in an interactive virtual environment. Participants had to choose between different exit routes under the influence of three different types of directional information: static information (signs), dynamic information (movement of simulated crowd) and memorized information, as well as the combined effect of these different sources of directional information. In contrast to signs, crowd movement and memorized information did not have a significant effect on human exit route choice in isolation. However, when we combined the latter two treatments with additional directly conflicting sources of directional information, for example signs, they showed a clear effect by reducing the number of participants that followed the opposing directional information. This suggests that the signals participants observe more closely in isolation do not simply overrule alternative sources of directional information. Age and gender did not consistently explain differences in behaviour in our experiments.

Planning of urban spaces and mobility has become a demanding task. All modes of transport have to be granted their very own right of way. Stakeholders of particular modes, tourists and commuters, old and young have their own needs and ideas and they all demand to be involved in the planning process of transport projects without having to dig into the words and numbers produced by traffic engineers. Microsimulation is a tool which accommodates both: the requirements that are set by the complexity of such projects, as well as the needs to produce easy-to-understand information and communication material. This paper demonstrates the capability of microsimulation through a French case study, including the planning and design of transport schemes for a busy city centre and urban area where all modes of transport are being used and there is a strong focus of public attention.
