Seventy percent of the traffic crash fatalities of Iran happen on rural roads, and a significant proportion of the rural roads network of this country is constituted of the main two-lane, two-way roads. The purpose of this study is to identify the most important factors which affect injury severity of drivers involved in traffic crashes on these roads, so that by eliminating or controlling such factors an overall safety improvement can be accomplished. Using the Classification and Regression Tree (CART), one of the powerful data mining tools, the crash data pertaining to the last three years (2006-2008) were analyzed. The variable selection procedure was carried out on the basis of Variable Importance Measure (VIM) which is one of the CART method outputs. The results revealed that not using the seat belt, improper overtaking and speeding are the most important factors associated with injury severity.

This paper presents a combinatorial model for the identification and simulation of a certain number of parameters of marine steam turbine plant for LNG tankers based on the classification and approximation neural networks. The model consists of two basic parts. In the first part, parameters are classified in adequate clusters by means of self-organizing neural network, while the combinatorial identification of clusters interrelationship is carried out in the second part by means of static feed-forward neural networks. In the following part, the successfulness of the achieved results is analyzed by generating an adequate rank-list of all identification-simulation models. This approach gives a clear insight into certain cluster interdependences which can significantly contribute in following applications which are based on the estimation and prediction of the lost sensor information not depending on the cause of their loss. Although all of the above is distinctly expressed in marine propulsion control systems, it should be pointed out that in this way significantly increased reliability and redundancy of the sensor information directly reflect on considerable increase in technical security of the whole ship as a floating object. KEY WORDS: marine steam turbines, marine control systems, neural networks, identification, clusterization

The capital and technology transfer into a certain region leads also to increased demands for logistic services. The transition to the logistic delivery organisation is very important under the conditions of accelerated technological development, in particular in the field of telecommunications and informatics, which enabled the advent of successful companies having a single employee. Owing to the mentioned technologies these companies get networked with similar companies, thus being able to solve all their needs by outsourcing the services or products of other networked companies. Higher speed and greater flexibility of operation of such companies has brought the following challenge: larger number of small companies has created a larger number of small orders that have to be delivered within the same unit of time. The logistics and distribution centres can represent a solution which maintains the speed and efficiency, and avoids costs of congestions and delays. KEY WORDS: capital transfer, technology transfer, logistics and distribution centres, optimisation

Multimodal transportation means transporting goods from a pickup point, where the operator receives the goods, all the way to the delivery location, using at least two different means of transportation, covered under the same multimodal transport contract and by only one document, regardless of the number or type of transportation vehicles used. The key factor to the optimal operation of multimodal transportation is the multimodal transport operator. It is up to this individual to compensate for various unpredictable circumstances, the complexity of the business processes, nature’s whims and carelessness. He must also organize and execute multimodal transport in all stages. Due to the above mentioned dangers and the fact that the area of liability insurance for multimodal transport operators is still being neglected, this article raises some valid points in favour of a proposal that would cover all of the transportation means as well as all the accompanying activities with a single insurance policy. The model includes 17 elements of liability insurance for a multimodal transport operator and all values which quantify the insurance elements in 2009 as well as the projected values for 2015, when progress is expected in the areas pertaining to the implementation of economical processes concerning transit development, as well as values for 2025, representing a period of innovation, reconstruction, optimization and modernization. With this supposed model for liability insurance of a multimodal transport operator, the foundation is laid for a liability insurance which would be used by a multimodal transport operator. KEYWORDS: transport insurance, multimodal transport, multimodal transport operator, multimodal transport operator liability systems

Efficiency analysis of transport systems can be carried out using numerous different techniques. Experts generally distinguish them as parametric and non-parametric methods, or else as methods using a production function, an index or not using anything of this kind. Based on the literature and on own research the present paper sets up a clear systematization of these techniques giving a brief summary of their essence while also providing examples of their application in the transport sector. Having elucidated each method, the author also outlines the correlation and the reliability of the techniques and presents a novel view which stresses the importance of links between the different techniques. KEY WORDS: efficiency measurement, transport, TFP, MPI, SFA, DEA, OCRA

This article investigates the possibility of optimizing the organization of a ship as a highly complex technical system. In this sense, the existing relationship between technology and the human as a user is considered. Using the socio-technical approach the aim is to identify the weaknesses in the existing technological and organizational ship’s system. Based on research conducted on the navigation simulator, socio-technical components that affect the safety of navigation have been observed. By subsequent comparative analyses of the implementation of technical solutions in accordance with the human requirements certain solutions are proposed and conclusions made. KEY WORDS: socio-technical model, ship organization, safety, effectiveness, technology indulgence, control systems, automation

Successful management of any sea port depends primarily on the harmonisation of transport supply and demand, whereas their incompatibility leads to a number of problems. The port, i.e. its management, through its operation and part of port policy may affect the planning of the construction or modernization of its port facilities. In doing so, the specified planning requires forecasting and quantification of the needs for infrastructural services of specified port, i.e. assessment of traffic demand. Accordingly, the basic problem of research in this paper is forecasting of traffic demand for the port services by applying the appropriate forecasting methods. In order to find ways of solving concrete problems in the port operations the methods for traffic demand forecasting are set by applying the methodology and the presentation of the application of economic forecasting methods. The selected methods of demand forecasting for port services in demand are illustrated and tested on the example of the Croatian largest cargo port, the Port of Rijeka. KEY WORDS: planning, forecasting, traffic demand, commodity flows, port capacity

The new generation of physical planning documents requires adaptation to new economic and other development plans as well as to new parameters of the modern society development. Therefore, it is necessary to insure high-quality planning foundations which will serve as the basis to determine the basic guidelines of physical plans. This refers especially to the need for integral consideration of the development of traffic and the traffic infrastructure in compliance with the space requirements and possibilities. In order to evaluate the objective parameters of physical and traffic planning, the traffic studies carried out as required for the production of the physical planning documentation of the new generation have been analyzed. The goal of research was to determine the credibility of infrastructure development plans predefined by the documents of physical planning from the region of the Primorje-Gorski Kotar County. The paper presents the results of initial research carried out for the requirements of producing the Physical and Traffic Integral Study of the Primorje-Gorski Kotar County and the city of Rijeka. According to overall distribution of responses it may be concluded that there is great gap in knowing the procedures of traffic and spatial planning among specialized traffic agencies and the rest of the respondents.
