abstract = {In a crowd, individuals make different motion choices such
as “moving to destination,” “following another
pedestrian,” and “making a detour.” For the sake of
convenience, the three direction choices are respectively
called destination direction, following direction, and
detour direction in this paper. Here, it is found that the
featured direction choices could be inspired by the shape
characteristics of the Voronoi diagram. To be specific, in
the Voronoi cell of a pedestrian, the direction to a Voronoi
node is regarded as a potential “detour” direction and
the direction perpendicular to a Voronoi link is regarded as
a potential “following” direction. A pedestrian
generally owns several alternative Voronoi nodes and Voronoi
links in a Voronoi cell, and the optimal detour and
following direction are determined by considering related
factors such as deviation. Plus the destination direction
which is directly pointing to the destination, the three
basic direction choices are defined in a Voronoi cell. In
order to evaluate the Voronoi diagram based basic
directions, the empirical trajectory data in both uni- and
bi-directional flow experiments are extracted. A time series
method considering the step frequency is used to reduce the
original trajectories' swaying phenomena which might disturb
the recognition of actual forward direction. The deviations
between the empirical velocity direction and the basic
directions are investigated, and each velocity direction is
classified into a basic direction or regarded as an
inexplicable direction according to the deviations. The
analysis results show that each basic direction could be a
potential direction choice for a pedestrian. The combination
of the three basic directions could cover most empirical
velocity direction choices in both uni- and bi-directional
flow experiments.},
