Qualitative–Quantitative Warning Modeling of Energy Consumption Processes in Inland Waterway Freight Transport on River Sections for Environmental Management

Abstract

The article concerns the assessment of the energy consumption of inland waterway freight transport on river sections in the context of environmental management. The research question was: Does the choice of the route determine the total energy consumption of inland waterway transport and therefore affect the potential of cargo transport of this mode? The article aims to indicate the directions of energy consumption by inland waterway freight transport depending on the route selection, the volume of transport, and the length of the route. The study was carried out on nine sections of the Odra River in Poland during the years 2015–2020. Statistical and econometric techniques were used, i.e., ANOVA, generalized linear models, Eta coefficients, Lasso and Ridge regularization, and X-average control charts (Six Sigma tool). Based on early warning models, river sections were identified that favor the rationalization of energy consumption in terms of the network. The sensitivity of the energy consumption of inland waterway transport to changes in the average distance and in the volume of transport was examined. With the use of Six Sigma tools, the instability of the energy consumption processes of inland waterway transport was identified, paying attention to the source of the mismatch, which was the increase in the average transport distance in the sections, where energy consumption increased due to the operational and navigation conditions of these sections.

Nas trilhas da gestão ambiental: aspectos conceituais e operacionais

“…Notadamente, a busca por processos mais sustentáveis gera ganhos como, por exemplo, redução de custos. Outra benesse que pode ser gerada com a gestão ambiental é a adequação das companhias para o cumprimento das diretrizes quanto a preservação do meio ambiente (Szaruga;Załoga, 2022). Além disso, pode-se considerar que a gestão ambiental representa uma via necessária para que se desenvolva uma cultura voltada para a sustentabilidade.…”

Identification of Causal Relationship between Attitudinal Factors and Intention to Use Transportation Mode

“…There have been many studies to deal with the influence of attitudinal factors on transportation [13][14][15][16][17]. Atasoy et al [18] distinguished public transportation and personal vehicle users by using the latent class model.…”

Links between the Energy Intensity of Public Urban Transport, Regional Economic Growth and Urbanisation: The Case of Poland

“…At the conceptualisation level, it should incorporate diverse avenues, including stage-based theories of development [11]. Sustainable transport is frequently described in terms of energy intensity (energy consumption patterns) and emissivity [9,[12][13][14][15]. In the context of passenger transport demands, sustainable transport is also referred to as sustainable mobility [16][17][18] as an important component of the worldwide agenda [9].…”
