As autonomous vehicle technology gains traction across Europe, Bulgaria is making strides towards integrating intelligent transport systems (ITS) into its roadways. The Ministry of Transport and Communications confirmed this development, noting that the country is in a pivotal phase of deploying these technologies, which comply with EU regulations aimed at facilitating connected and automated mobility.
Recent reports indicate that cities like London are preparing for robotaxi services, while Volkswagen plans to introduce self-driving minivans in a third European city outside Germany. Meanwhile, Toyota is set to launch an experimental “Woven City” in Japan by the end of 2025, designated for testing autonomous cars and robots. These advancements underscore a growing momentum in the autonomous vehicle sector across Europe and beyond.
In response to a BTA inquiry, the Bulgarian Ministry outlined progress in meeting the requirements of Directive 2010/40/EU, which establishes a framework for ITS in Europe. Amendments to the directive, particularly Directive (EU) 2023/2661, further prepare member states for the deployment of autonomous vehicles. The Ministry emphasized the need for cooperative intelligent transport systems (C-ITS) that allow vehicles to communicate with each other and with road infrastructure, enhancing safety and efficiency on the roads.
Assen Nachkov, a PhD student at the Institute for Computer Science, Artificial Intelligence and Technology (INSAIT) at St. Kliment Ohridski University of Sofia, highlighted the economic factors affecting the timeline for deploying autonomous vehicles in Bulgaria. He noted that while the technology is advancing, its widespread rollout depends significantly on economic viability and public acceptance. “It is difficult to give a precise forecast, as the adoption of such technology will have a significant impact on the economic structure of the transport industry,” Nachkov stated.
INSAIT has recently showcased its innovations in autonomous vehicle training, revealing a series of developments known as DiffSim Trinity. This initiative aims to create advanced simulations that enhance how autonomous vehicles learn to navigate and make decisions based on their surroundings. Nachkov identified several steps necessary to expedite vehicle deployment, including improving infrastructure, establishing testing zones, and clarifying legislation concerning liability and safety standards.
According to Nachkov, the initial deployment phase is likely to be driven by private companies eager to capitalize on economic opportunities in the market. However, these companies face substantial challenges, including high capital costs for new vehicles and the necessity of creating precise maps tailored to local conditions. Moreover, the legal framework poses a significant hurdle, with potential pushback from various stakeholders concerned about competition and safety.
Public trust is another critical factor influencing the deployment of autonomous vehicles. Nachkov suggested that effective information campaigns could build confidence in the technology, thereby increasing demand. He indicated that greater public acceptance could be bolstered by improving the overall economy, as higher incomes typically lead to increased demand for innovative technologies.
In terms of vehicle automation levels, the classification ranges from Level 3, which represents conditional automation, to Level 5, indicating full automation. As the Ministry of Transport and Communications continues to refine legal and operational frameworks for ITS, the path for autonomous vehicles on Bulgarian roads is gradually being paved.
As this technological evolution unfolds, the implications for the transport industry are profound. Not only could autonomous vehicles reshape urban mobility, but they also present opportunities for economic growth and innovation. With continued advancements and a supportive regulatory environment, Bulgaria may soon witness autonomous vehicles navigating its streets, joining the ranks of other European nations committed to embracing this transformative technology.
