1. Theoretical model for determination of airspace capacityBranko Lučovnik, Martin Lipičnik, Domenik Lebar, Janko Blatnik, 2002, review article Abstract: In the last decade, the constant air traffic growth has brought certain problems as well. While aircraft production and airline functioning are being stimulated by the competition, the situation in air traffic control and in infrastructure component is completely different. Air traffic management (ATM) is still owned by the state. The state, however, is known for the fact of not being a good manager and is solving problems slowly and not efficiently because of its large administration. There is a very strong trade union movement functioning in ATM system, which makes several rational decisions impossible. Critics of the current ATM system in Europe warn of increasing problems-delays and operational expenses. The control component is the only one among the four components of air traffic, which has not been liberalised and harmonised yet. There is no competition in the fields of air traffic. All matters are taken care of by CAA or by semi-private companies, owned by the state. According to air carriers which have to put in 4-9% of business expenses into terminal-and over-flights charges, these expenses are far too heavy a burden.

2. System dynamic model of measures for reducing the number of road accidents due to wrong-way movement on motorwaysDarja Topolšek, Martin Lipičnik, 2009, other scientific articles Abstract: This paper provides a system dynamic model for reducing the number of motorway accidents due to wrong-way driving. Motorway accidents are often fatal due to high speeds. It is therefore necessary to carry out all the possible countermeasures in order to achieve adequate traffic management. One of the reasons for motorway accidents is driving in the wrong direction. Based on the analysis of the data on motorway accidents caused by driving in the wrong direction and based on the knowledge of individual project elements of junctions and slip roads, this paper will focus on this area. The possible countermeasures, presented here for preventing drivers from driving in the wrong direction on motorways drastically reduce the number of U-turn maneuvers that result in driving in the wrong direction and influence the level of safety on motorways. With the help of this model of system dynamics the countermeasures for reducing the number of such drivers will be confirmed and their effects will be shown.

3. Monte Carlo simulation-based approach to optimal bus stops allocation in the Municipality of LaškoDejan Dragan, Tomaž Kramberger, Martin Lipičnik, 2011, original scientific article Abstract: The paper addresses the problem of optimal bus stop allocation. The aim is to achieve reduction of costs on account of appropriate re-design of the process of obligatory transportation of children from their homes to the corresponding schools in the Laško municipality. The proposed algorithm relies on optimization based on the Monte Carlo simulation procedure. The number of calculated bus stops is required to be minimal possible, which can still assure maximal service area within the prescribed radius, while keeping the minimal walking distances pupils have to go across from their homes to the nearest bus stop and vice versa. The main issues of the proposed algorithm are emphasised and the working mechanism is explained. The presentation of calculated results is given and comparison with some other existing algorithms is provided. The positions of the calculated bus stops are going to be used for the purpose of physical bus stops implementation in order to decrease the current transportation costs.

4. Identification of drivers in traffic accidents and determination of passenger position in a vehicle by finger marksMatej Trapečar, Martin Lipičnik, Jože Balažic, 2012, review article Abstract: The following paper aims to illustrate certain investigative activities in the forensic analysis and examination of the scene of traffic accidents. When a traffic accident occurs, the scene must be secured as soon as possible to enable professional and proper forensic investigation. Failure to secure the accident scene might result in losing or contaminating the traces, which makes it more difficult to prove or explain trace evidence in further procedure or even makes such evidence inadmissible. The topic is discussed from the viewpoint of crime scene examination, since analysing and investigating traffic accidents requires a great deal of expertise and attention of the investigators. Complex traffic accidents include feigned accidents, hit-and-run accidents as well as accidents in which the driver and passengers, dead or alive, need to be identified. In identifying the passengers, standard criminal investigation methods as well as police forensic and forensic medicine methods are followed. Such methods include confirming the identities with identity documents, other documents and vehicle ownership, fingerprints, biological traces, fibre traces, contact traces, traces of physical injuries on the driver and passengers, etc. According to the results obtained in fingerprint detection on human skin surfaces, this method can also be applied in confirming physical contact between the driver and the passengers in the accident, e.g. in the event of moving the victims and changing the scene of the accident.

5. Competitiveness by requisitely holistic and innovative logistic managementMatjaž Knez, Bojan Rosi, Matjaž Mulej, Martin Lipičnik, 2010, review article Abstract: In the age of global expansion of business operations and contemporary way of life the material and information flows in and between different companies are growing rapidly; they are thus becoming more and more difficult to manage. Had business functions in companies been dealt with separately until now (purchase, production, finances, sale, etc.), today the emphasis is placed on their integration due to their interdependence. By studying supply chains inside and between business partners, companies can gain competitive advantage and become more adjustable, taking the increasingly changing market circumstances into account. This enables them to meet consumers' demands and expectations requisitely holistically. Taking all the crucial activities into account, the logistics management plays a key role in the companies facing the challenges of the new millennium. Based on the numerous megatrends, which influence each and every business entity, this article aims to explain the increasing strategic importance of logistics management. The latter may not be dealt with one-sidedly as a cost; moreover, the key aspects such as competitiveness as well as long-term existence of a company must also be considered. Innovation and systemic thinking in it and about it are needed.

6. Collaborative behaviour as a facilitator of integration of logistic and marketing functions : the case of Slovene retailersDarja Topolšek, Anton Čižman, Martin Lipičnik, 2010, original scientific article Abstract: Collaborative behaviour and various aspects of comparing collaboration with coordination and cooperation present the basis for more detailed assumptions concerning the importance of integrating logistic function with the marketing function. The collaborative behaviour dimension of inter-functional integration presents a system of mutual visions, decision-making and collective responsibility to provide results, services or a product. Logisticians often define integration within the framework of the supply chain, yet they neglect the internal integration or the integration between individual departments or functions in a company. Defining internal integration and its level as well as the connection with the level of collaborative behaviour is the basis of the research part of this paper. The quantitative research part studies whether and to what extent collaborative behaviour influences the level of internal integration between logistic and marketing functions. The research is based on a quantitative analysis of results of the survey that was conducted in Slovene retail companies.

9. Fiscal impact of electronic fee collection system on long-run efficiencyTomaž Kramberger, Uroš Kramar, Andreja Čurin, Marko Cedilnik, Martin Lipičnik, Viktor Tajnšek, 2012, original scientific article Abstract: The transport infrastructure is extremely important for economic development and the labour mobility and competitiveness of European economy. However it is becoming increasingly difficult for government to publicly fund transport infrastructures. Therefore the decision to implement toll roads in Europe as a transport-policy instrument is an important shift in the funding of infrastructure. Adoption of appropriate technology has implications on the efficiency of the system. The mathematical model developed upon and simulations were carried out on several scenarios given the different types of technology. The results suggest that DSRC technology employed on motorways to be the most efficient.
