The focus of this
research is to investigate the wayfinding strategies and route choices for
emergency services, in particular, police services. In order to achieve this
objective, during several months, members of the police force of Ghent (Belgium) registered their routes
using a GPS device. For each registered trajectory, they completed a survey
containing several questions about that specific journey. The recorded tracks
were analysed and compared with theoretically calculated paths, like the
shortest path, fastest path, and simplest path, calculated by different route
planning software. Further, this study analyzes how the participating emergency
service officers decide which trajectory they consider as optimal. We also
registered which tools the police officers use during their emergency
intervention: maps, GPS, guidelines via radio communication and so on. In
addition, the participants were asked why they preferred a particular path.
Analysis revealed that the route followed by experienced police officers and
the theoretically computed paths linking the two nodes in the street network
often differ significantly. After analysing all the data, the paper presents
which theoretical path matches best the human behaviour, using cartographical
representations. Finally, the wayfinding strategies, which are typical for the
target group, are described.
