1. Exploring an infrastructure investment methodology to risk mitigation from rail hazardous materials shipmentsAli Vaezi, Manish Verma, 2021, izvirni znanstveni članek Opis: Railroad is one of the primary modes to transport hazardous materials (hazmat) in North America. For instance, Canadian railroads carried around 50 million tons of hazmat in 2018. Given the inherent danger of trains carrying hazmat, this study aimed at exploring a novel way towards mitigation of the associated risk. This study sought to investigate whether proper rail track infrastructure investment can mitigate the risk from hazmat shipments. To this end, a methodology was developed and then applied to the Canadian railroad network. The proposed three-step methodology captured the differing perspectives of rail carriers and regulatory agencies, and entailed (1) ascertaining the risk-level of various yards and links in the given railroad network, (2) specifying potential candidates for infrastructure investment, and (3) finding the optimum set of investment decisions. The proposed methodology was then applied to the Canadian railroad network to demonstrate that significant risk-reduction can beachieved by adding alternative rail-links around the riskiest locations (i.e. the network hot-spots), and also to show that risk-reduction function is non-linear with non-monotonous behavior. The study showed the possibility of significant hazmat risk reduction through alternative rail-links that could take traffic away from the network hot-spots. The methodology and the resultsfrom the Canadian case can be used by railroad companies and policy makers to estimate the value of potentially risk-reducinginfrastructure investments.

3. Examine the rural infrastructure development fund (RIDF) in KarnatakaSathisha, Medhavini S Katti, 2023, izvirni znanstveni članek Opis: This study examined the relationship between the Rural Infrastructure Development Fund (RIDF) and agriculture development in Karnataka from 1995 to 2021. While presenting the budget speech for 1995–1996, the honorable union finance minister introduced the RIDF program. The RBI monitors the funding for the RIDF program through NABARD, which has a corpus of Rs. 2,000 crores from commercial and regional banks, among other sources. The program funds the social sector, small to medium irrigation, rural connectivity, and agricultural and related activities. The study evaluated the performance of the RIDF in the State critically. It also observed that several projects remained incomplete even after taking loans from the RIDF. Many states might be unable to take on this financial load due to most governments' dire financial circumstances. Despite this, there have been some physical advancements in rural irrigation, roads, and bridges. The nation's states and regions, however, do not all share the same achievement levels, therefore suggesting necessary steps to ensure proper fund utilization and decrease rural poverty and intra-regional disparity in Karnataka.

4. Impact of transport trends on sustainability in the Western Balkans : a future-oriented business sector perspectiveTomislav Letnik, Katja Hanžič, Matej Mencinger, Drago Sever, 2024, izvirni znanstveni članek Opis: Abstract This study examines the impact of emerging transport trends on the Western Balkans and their potential to improve the sustainability and efficiency of the transport sector in the region. In the context of global efforts to reduce environmental impacts and improve transport safety, the study aims to better understand the perspective of the business sector in order to align strategic planning for the introduction of new transport technologies and practices with the expectations of the business sector. Using a questionnaire-based survey on the Mentimeter platform, the study gathers insights from 49 transport and logistics experts. The analysis uses violin plots and heat maps to visualise the expected impact of the identified trends. The results show a consensus among the experts that the emerging trends are likely to lead to a reduction in accidents, congestion, and emissions, while at the same time increasing operating costs and investment in infrastructure. In particular, trends such as alternative fuels, electrification, and smart city initiatives are highlighted as important drivers for reducing emissions. The study concludes that while these trends are likely to lead to the achievement of environmental and safety goals, they also lead to economic challenges as operating costs increase and significant infrastructure investment is required. The study emphasises the need for strategic investment, policy adjustments, and capacity building to lead the Western Balkans towards a sustainable transport future.

8. Influence of road transport infrastructure on agricultural sector development in NigeriaOlusogo Ogunleye, Akinyemi Ajibola, Oluwafemi Enilolobo, Olufolakemi Shogunle, 2018, izvirni znanstveni članek Opis: The study investigated the effects of road transport infrastructure on agricultural sector development in Nigeria from 1985 to 2014, using secondary annual time series data on agricultural development (proxy by gross domestic product in the Agric sector) road transport infrastructure (proxy by length of paved road per square kilometer of area) export and capital, all obtained from the Central Bank of Nigeria (CBN) [3], and National Bureau of Statistics (NBS) [16], statistical bulletins. The data were analyzed using Granger Causality test and Ordinary Least Square estimation techniques. The study concluded that a positive and statistically significant relationship exists between road transport infrastructures (LRT) also evidence was found of a unidirectional causality from agricultural sector development to transport infrastructure. The study, therefore, recommends that adequate and timely maintenance of existing roads should be carried out as well as enacting appropriate regulations that ensure proper implementation and completion of new road construction contracts in the country in order to boost agricultural sector development, reduce wastage of farm produce and increase the possibility of economic diversification.

9. Restraints and opportunities of the Romanian rural areasVasile Surd, 2010, pregledni znanstveni članek Opis: Although Romania disposes of an extremely valuable agricultural land, it has proved to be insufficient and irrationally exploited in the last two decades, as a direct consequence of the programme for returning the agricultural areas to the former individual landowners. The lack of technological agricultural means for cultivating the land, its excessive allotment, as well as the rather inappropriate involvement of the political factor in the decision making process and the invasion of imported agricultural products have generated a continuous process of degradation of the rural life as a whole and certain repercussions on the food safety. Currently, more than 50% of the Romanian agricultural area is not being cultivated, while the state imports more than 70% of alimentary products every year.

10. Estimating marginal infrastructure cost in new infrastructure charging modelMarjan Sternad, Timotej Jagrič, Bojan Rosi, 2017, izvirni znanstveni članek Opis: Competitiveness of rail transport compared to road transport has been reducing, especially on regional railway lines. To improve this situation, the EU adopted various directives and regulations to increase efficiency of railway undertakings. In this paper we present an organizational and economic model based on European policies for local railway system. The organizational model is based on multi-criteria decision analysis. For the economic model we used an econometric approach to estimate the cost function and marginal costs in regional lines, which constitute the basis for railway charges. By implementing such an organizational model, the functioning of the railway network will improve. The research found that a change in the existing model of calculating costs of infrastructure use would bring economic effects for the railway infrastructure manager and the providers of transport. Using the proposed model we also found that it is reasonable to increase the flow of goods on unused regional railway lines because the railway infrastructure maintenance costs are inelastic with regard to transported gross tons.
