The commentary emphasized that unmanned delivery vehicles should not only adhere strictly to established rules but also demonstrate a capacity for flexible, situation-aware responses. Recently, an incident involving an unmanned delivery vehicle highlighted this necessity, as the vehicle failed to comprehend instructions given by workers. Following the deployment of unmanned delivery vehicles in various locations, challenges such as traffic congestion and potential safety risks have surfaced. In response, the Gaochun District in Nanjing has already engaged in discussions with relevant delivery companies to proactively mitigate potential risks.

While unmanned delivery vehicles offer the promise of enhanced delivery efficiency and cost reduction, their seamless integration into the urban traffic ecosystem hinges on clearly defining the rights and responsibilities of all stakeholders involved and refining operational management frameworks. As technology continues to evolve, it is anticipated that automated traffic participants will increasingly harmonize with traditional road systems.

Addressing the challenges at hand can be achieved through strategies such as leveraging algorithm-optimized scheduling, implementing vehicle-to-vehicle communication protocols, and installing emergency communication systems. Moreover, the intelligence of unmanned delivery vehicles is contingent upon a vehicle-road coordination traffic environment. Ultimately, the establishment of a smart traffic ecosystem is contingent upon society's collective adaptation to coexisting harmoniously with unmanned delivery vehicles.
