Abstract
Urban intermodality is an increasing phenomenon and nowadays modal choice
nodes, nodes within urban networks from which it is possible to reach other
nodes by using different transportation modalities, play a relevant role in the
analysis of passenger mobility. There is hence the need of evaluating the
performance of such nodes with the aim of making more convenient multimodal
paths.
In this work we focus on the problem of determining the attractive capacity of
modal choice nodes in urban networks; the goal is to identify those nodes that
could be attractive poles for modal exchanges and become location of new
services, such as parking places, bus stops and informative panels.
Starting from relevant Origin – Destination (O-D) paths that are derived from
the demand of mobility, we analyse the possible intermodal nodes by evaluating
the role that such nodes play within urban networks on the basis of some
structural attributes of the network itself. Inspired by the gravitational models,
that are more generally used in the competitive location problems, we determine
the attractive capacity of the well performing previously selected intermodal
nodes; the aim is to verify whether the good behaviour of the modal choice
nodes inside the transportation network is also perceived by users.
We report on some data related to the city of Genoa that for its topological
and geographical structure and the wide offer of the public transportation system
is well suited for intermodality.
Keywords: urban O-D paths, intermodal networks, generalized cost functions.
