In this work we present a model to simulate container service of maritime transport on an international scale, considering the alternatives hub and spoke and point-to-point. Given the alternative hub and spoke, the choice of hub port is simulated. Several model specifications are proposed. An experimentation according to the independency of the two choices, maritime service and hub port, is carried out for the Mediterranean basin.

In this paper, an integrated network and transit route design problem is analysed. A two-step design approach is proposed: first a trial transit route is designed using a greedy algorithm, second the road network is optimized taking into account, in the objective function, also of the route cost for freight. At the end of procedure, also the vehicle routing problem for city logistic distribution is designed using optimized road network and the reserved lanes for bus. The whole problem is formulated as a continuous-discrete problem, to consider both the topology and the link capacity.
