We present an intelligent solution for protecting public spaces and enabling flexible vehicle access control. It combines a robust security element with a natural urban design. CITY GATE is a modern mobile barrier ideal for squares, events, and protected zones where it is necessary to temporarily close or open vehicle access. The system allows both sides of the barrier to extend, reliably preventing vehicle entry during events or restrictions. After the event ends, the barrier can simply be retracted, and the area becomes freely accessible again. Key advantages include, for example, temporary closure of vehicle access (e.g., during events in public squares), a retractable two-sided design, quick restoration of traffic flow after retraction, no need for construction work or excavation, and integrated safety features (photoelectric sensors, light and sound signaling). It combines functional protection with urban design. CITY GATE is a flexible solution for access control and protection of public spaces without permanent alterations to the environment.
