Modelling operational, economic and environmental performance of an air transport network
Milan Janić, 2003, original scientific article

Abstract: The paper models the operational, economic and environmental performance of an air transport network consisting of airports and air routes connecting them. The operational capacity represents the operational performance. Thresholds on the networkćs environmental burdens reflect the environmental performance. The economic performance comprises the networkćs profits. Modelling the network performance includes using integer programming techniques to maximise total network profits for given operational capacity and environmental constraints under conditions where environmental externalities are internalised.

High-speed rail and air passenger transport : a comparison of the operational environmental performance
Milan Janić, 2003, original scientific article

Abstract: This paper presents an overview of the environmental performance of high-speedrail (HSR) and air passenger transport (APT) in the European Union (EU). This performance embraces the direct environmental burdens/emissions such as energy consumption, air pollution, noise, landtake and land use, safety and congestion. A comparison of the marginal values of particular burdens/emissions and their costs (externalities) is carried out. The results have shown that significant mitigation of the impacts and savings of costs could be achieved by substitution of air passenger transport by high-speed rail. The substitution can be carried out through competition and complementarity of operations of both modes.
Keywords: high-speed rail, air passenger transport, interactions, environmental performance, burdens, emmisions, externalities

Liberalisation of European aviation : analysis and modelling of the airline behaviour
Milan Janić, 1997, original scientific article

Abstract: This paper deals with the analysis and modelling of behaviour of the Western European airlines during the first phase of the gradual liberalisation of the EU (European Union) aviation market. The framework for monitoring this behaviour and appropriate methodology for registering significant changes in the airline industry, specific airlines, and the aviation market itself has been developed. Three classes of empirical models have been estimated: airline growth and financial performances, airline mergings and alliances by holding of equity stakes in partners, and airline relationships (cooperation and/or competition) on the EU air route network consisting of five sub-models. The EU airline sub-models are: market share, market concentration, air travel demand, quality of services, and pricing policy. The least-square regression technique has been applied over the cross-sectional data for making the empirical estimates.
Keywords: European aviation, liberalisation of the aviation market, Wester European airlines, externalities

An assessment of risk and safety in civil aviation - dialogue from the black box
Milan Janić, 2000, review article

Abstract: Risk and safety have always been important considerations in civil aviation. This is particularly so under current conditions of continuous growth in air transport demand, frequent scarcity of airport and infrastructure capacity, and thus permanent and increased pressure on the system components. There is also the growing public and operators' awareness of these and other system externalities such as air pollution, noise, land use, water/soil pollution and waste management, and congestion. This paper offers an assessment of risk and safety in civil aviation. It deals with general concept of risk and safety, describes the main causes of aircraft accidents and proposes a methodology for quantifying risk and safety.
Keywords: risk, safety, civil aviation, externalities
