Several efforts have been centered on the improving of
the quality of service of public transportations in
order to face the increasing of the demand.
Consequently, in the latest decade, a growing body of
advances concerning several aspects of public
transportation planning process has appeared in the
operation research literature. Some classes of Petri
Net (PN) are used for the graphical describing, the
analysis of flows and the control in the studied
systems. Due to the characteristics of the public
transportation systems, PN models of such systems are
very complex. To overcome this inconvenience, we
introduce in this paper a new class of PN. This allows
the modeling and the analysis of complex public
transportation systems. This particular class of PN is
described and defined and we show that it has
interesting properties. We illustrate the interest of
such a tool with a line planning problem for which
several lines architectures are possible and one has to
choose the best one.
