Modal Competition and Complementarity: Cost Optimization at End-User Level

Abstract

The paper aims to identify possible methods for balancing the allocation of transport flow on modal subsystems in order to efficiently use the infrastructures and reduce the negative effects of today’s unbalance. The aspects of intermodal competition are reviewed, considering the economic concepts regarding the substitutability of transportation services, conformation degree to the perfect competition model and the nature of cross elasticity demand.

A top-down analysis over the whole infrastructure assembly is performed. The results, under the presumption of valid work hypothesis, indicated that for further analysis the set of networks transferring material flows can be assumed as disconnected from the other networks sets transferring energy, informational and values flows.

The second part of the paper develops, for that disconnected networks, a generalized cost optimization model for multimodal transportation, where the comfort and safety are accounted. Thus, the performance of the existing algorithms based only on trip length, trip duration and energy consumption can be significantly improved. Additionally, the author proposes three new independent types of modal analysis that allow end-users and companies involved in transport organization to optimize their modal choice and the whole transport process organization.

Analyse of the Challenges for Safe Transition from Individual Intraoperable Railway Systems to the Single European Interoperable Railway System

Abstract

Due to different reasons a significant modal shift from railway to road transport took place over last decades. The basic reasons are pointed in the paper introduction together with contradicting transport policy taking into account environmental and economical challenges. Political vision to stimulate modal shift from road and air to railway cannot become true without achieving railway technical and operational interoperability. Paper describes wide range of technical barriers between individual intraoperable railway systems in civil engineering structures, traction power supply, control command and signalling and the ways, which are being applied to ensure stepwise converging of the technical solutions taking into account safety and technical compatibility, as well as other essential requirements, namely: reliability, accessibility, health and environment.

The potential of intermodal transport projects in Romania

Abstract

The transport infrastructure sector is facing challenges related to the decarbonisation, financing and integrated developments, which need to be overcome so it can gain a competitive advantage among the strategic economic sectors. Known as a major pollutant, with 23.3 % of the total EU-28 GHG emissions in 2014, one of the transport policy objectives is to lower this percentage, by focusing on innovative solutions and modal shift (Eurostat, 2016). The White Paper (2011) promotes a sustainable development, aiming at a reduction by 60% by 2050 of the carbon emissions generated by the transport sector and at a modal shift from road to rail or waterborne transport for freight transport over 300 km with 30% by 2030, and more than 50% by 2050. The focus on an integrated development of the transport sector at the European level was reinforced with the adoption of the EU Regulation no. 1315/2013, marking the transition from a patchwork of different projects towards a vision for the achievement of an EU transport network. Moreover, another challenge is related to the scarce availability of the public money, making it necessary to attract private parties in the development of the transport infrastructure projects (The Investment Plan for Europe, 2014). Supporting the development of the intermodal transport is a way of surmounting the obstacles that this sector is confronting with, which is being implemented in Europe. The intermodal transport is introducing a paradigm shift, allowing the integration of the different transport modes together with their own advantages, as opposed to competing stand-alone modes and it can aid in the fight against climate change, scarce financial resources and congestion This article aims at determining the potential of Romania, as a member of European Union, to develop intermodal transport projects, to identify the funding sources, the obstacles and the solutions to promote the successful implementation of such projects.

Universities as Embedded Knowledge Hubs and the Challenge of Local Development the Us Lessons and the Italian Case

This article discusses the claim of a new paradigm in the knowledge production and diffusion process, and the need to assess the regional and local implications of this modal shift. After introductory remarks included in the first part of the paper, its next section introduces the theme of localisation of knowledge as a source of regional development; section three examines the lessons we can extract from the US university system (with a particular regard to the case of Johns Hopkins University and the recent project for a biotech park in the city of Baltimore); in section four an illustration of the Italian University system leads to a description of the current evolution of the University of Bologna toward a new entrepreneurial role. The last part of the paper discusses the embedded role of universities in the light of the two cases presented in the previous sections and draws the conclusions in terms of regional policy.

Baulandpotenzialanalyse als Instrument zur Umsetzung nachhaltiger Siedlungsentwicklung – das Fallbeispiel Biosphärenpark Wienerwald

. Unternehmen wurden nach ihrer qualitativen verkehrsinduzierenden Wirkung in einem „Mobilitätsprofil“ mittels zweier Kriterien bewertet: dem Bedarf nach Erreichbarkeit sowie dem „Modal Shift“ (Verkehrsverlagerung) des von diesem induzierten Verkehrs. Dieses Mobilitätsprofil wird für Unternehmenstypen erstellt, die sich nach dem quantitativen Mobilitätsaufwand unterscheiden (wie etwa Anzahl der Arbeitskräfte, Besucherintensität oder Umfang des Gütertransports) ( Martens/van Griethuysen 2000 : 2 ff). Weiters wurden potenzielle, unverbaute Standorte in einem
