Abstract
In recent years network design problems have received growing
consideration due to the possibility of finalizing resources
destined for the transport system, for the pursuit of specific
issues of efficiency: reduction of travel time, of congestion, of
pollution, and of consumption.
The main efforts have been channeled towards the road network
design and various techniques have been put forward, whereas little
attention has been given to the public transportation system.
In this paper a frequencies design model for a transit system is
described. After the introduction, where the sate of the art is
examined, in the second section general definitions and notations
are posed, the frequencies determination problem is formulated as
an optimization problem and the user's behavior model used in
the urban area is summarized.
In the last section, a solving approach for the proposed model
is analyzed and preliminary results obtained in an urban area are
discussed and issues for improvement are presented.
