    Land transport infrastructures servicing Ligury's ports: a potentiality analysis
    (EUT Edizioni Università di Trieste, 2001)

    In this study, road, highway and railway infrastructures that are linked to the ports of Savona, Genoa and La Spezia are briefly presented. An estimate of the transport capacity of these infrastructures is developed, with the aim of comparing it with the forecasts of the increase of harbour traffic; this leads to assessing the residual potentiality in the period 2000-2010. Analysis results point out various critical situations, especially for what concerns road transport. Therefore, a gradual redistribution is proposed from road to rail mode that still offers a noticeable residual potentiality, despite of its extensive utilisation of some sections. Lastly, the role that a more strict integration of maritime ports, according to the harbour system concept, can have in enforcing the railway mode is mentioned.

    Some observations on the organisation of demand responsive transport service
    (EUT Edizioni Università di Trieste, 2001)
    Mageean, JF

    This paper presents new concepts of Demand Responsive Transport (DRT) service provision emphasising the advantages of route flexibility. The paper reviews briefly the development of DRT services world-wide and then focuses on the new service concepts that have been developed as part of the DGXIII-funded SAMPLUS project. Five European demonstration sites are introduced and the experience of the Italian case-study (Florence) is taken as a detailed example. The evaluation of DRT services comprises four assessment categories (economic viability, service provision, technical performance and market projection). In conclusion, discussion centres on the contribution of DRT to future public transport provision and the barriers that must be overcome in order to facilitate widespread adoption.

    Modelling activity location choice

    Analysing the development of cities and regions has been one ' of the great social science tasks of the last century. The 1 analytical approach to urban systems modelling is very recent, however some complex models, named integrated land-use/ transport models, have been developed and used in ail over the world. However, these models do not stress the transport component, while they give much more importance to modelling land-use. In this paper, simulated land-use interactions are relative to residential and economic activity location, based on behaviourally consistent accessibility measures (logsum variables) as well as potential demand for economic activities and available floor-space. Both "active" and "passive" accessibility have been defined and considered.

    Vertical integration within the logistic chain: does "regulation" play rational? The case for dedicated container terminals
    (EUT Edizioni Università di Trieste, 2001)
    Cariou, Pierre
    The liberalisation process of European port markets is similar to the one implemented in most of the networks industries (telecommunication, gas, water, airlines...). It takes place during a period of vertical integration within the logistical chain. The basic idea of this article is to present the main features of those processes and their major implications in one case of vertical integration: dedicated container terminals (DTs). A first section compares port systems and general network characteristics. It stresses that the Community efforts to complete the single market, the pressure from both customers and competitors, the withdrawal of public funding, have induced a general move towards liberalisation. This liberalisation is also justify within a network industry by economies of scale and positive network externalities. Analysis of network liberalisation process also stresses that it generally goes hand-in-hand with regulatory reforms that need to achieve a "public acceptance" (i.e. determining in a clear way the main economic effects of liberalisation) and to combine efficiency, competition and the provision of Universal Service Obligation (USO). A second section focuses on one question that usually raises when analysing liberalisation process. How to create conditions of entries (ex ante,) and how to make sure that those conditions will not reduce the level of competition (barriers to entry) and the provision of USO (ex post,)? The case of DTs in container market is analysed with respect to competition issues. DTs are private agreements between one or more carriers and a port operator or authority. They entail both a geographic -the use of facilities in a defined part of the terminal- and a temporal dimension -the use of facilities for a certain period of time. It represents a case of vertical integration within a network industry. An hypothetical queuing model is developed to investigate under which assumptions this vertical integration could reduce competition in the long run. This last section underlines that we can not consider that to maintain a multi-user terminal within a port or to split the port area into dedicated and multi-user servers allowing for some restricting agreement is not neural when considering the level of competition. It induces to investigate access and interconnection pricing in port industries. A rule to internalise the potential benefits and costs resulting from integration is finally consider: The Efficient Component Pricing Rule (ECPR). The final conclusion that comes from previous developments is that liberalisation when combining with vertical integration process appears to be a complex process. It requires both to select the infrastructures and services to liberalised, to "protect" the USO and at the same time, to analyse the impact of liberalisation on heterogeneous (geographic and economic) European port markets.
