The study of pedestrian dynamics has become in the latest years an increasing field of research. A relevant number of technicians
have been looking for improving technologies able to detect walking people in various conditions. Several researchers have
dedicated their works to model walking dynamics and general laws. Many studiers have developed interesting software to simulate
pedestrian behavior in all sorts of situations and environments. Nevertheless, till nowadays, no research has been carried out to
analyze all the three over-mentioned aspects. The remarked lack in literature of a complete research, pointing out the fundamental
features of pedestrian detection techniques, pedestrian modelling and simulation and their tight relationships, motivates the draft
of this paper.
Aim of the paper is, first, to provide a schematic summary of each topic. Secondly, a more detailed description of the subjects is
displayed, pointing out the advantages and disadvantages of each detection technology, the working logic of each model, outlining
the inputs and the provided outputs, and the main features of the simulation software. Finally, the obtained results are summarized
and discussed, in order to outline the correlation among the three explained themes
