Abstract

The dynamics in the global automotive industry are constantly evolving, opening pathways to new markets and technological paradigms. Advancements such as H2 and e-vehicles present clear opportunities but also entail challenges of uncontrolled development, particularly with the growing influence of China in the EU. Traffic accidents involving vehicles with electric propulsion pose specific challenges for investigators and analysts. Analyses reveal increased complexity and harmfulness of these accidents, emphasizing the need for new methods of investigation and damage assessment, as well as for tightening regulations. The production of e-vehicles faces financial challenges and technological demands. Production efficiency, including the use of one-piece chassis panels, is crucial for competitiveness in the market. The future of the automotive industry in the EU requires complex strategies focused on the development of e-vehicles for urban needs, H2 technology for freight trucks, and alternative fuels to ensure energy independence. Traffic safety is gaining importance, recognizing energy as a key factor in global security. Attitudes of countries like the Netherlands towards e-vehicles vary, with the issue of electric energy availability highlighted as significant. In this complex landscape of the automotive industry, contemplating the future requires a balance between technological innovation, safety, and sustainability.

The influence of the corona virus pandemic on the characteristics of vehicle flow on the e-661 highway

Original scientific paper

DOI: 10.7251/JTTTP2401016G

Abstract

In this work, the characteristics of the traffic flow on the section of the Gradiška- Banja Luka highway, which is part of the European road route E-661, were analyzed in the period from 2019 to 2022. Data on the size of flow requests were taken from the database of the toll station “Jakupovci” on the Gradiška- Banja Luka highway. When defining the size of the flow request, the structure of the traffic flow was also taken into account, in accordance with the categories according to which the toll is collected. The period in which the analysis of flow characteristics was performed also includes the period in which the coronavirus pandemic reigned, when certain travel rules and prohibitions were in force. In accordance with that, the work will specifically analyze the impact of the COVID 19 pandemic on the characteristics of the traffic flow on the Gradiška- Banja Luka highway section. Given that the

„Jakupovci“ toll station is the busiest toll station on the Gradiška- Banja Luka highway, the results of the analysis can be applied to other sections of highways in the Republic of Srpska.
