Busan Port Authority (BPA) developed Korea’s first GPS-based Virtual Gate System to address severe truck congestion at Gamman Container Terminal in Busan North Port. The congestion stemmed from a unique operational structure in which trucks bound for an off-dock container yard (ODCY) were required to pass through the terminal gate solely to obtain container location information, creating unnecessary detours and bottlenecks.
Rather than investing significant time and cost in constructing a new physical gate, BPA redefined the problem and digitalized the gate function itself. Using geofencing, direction-vector analysis, multi-layer GPS validation, and AI-based GPS error correction, the system automatically recognizes trucks entering a designated virtual zone and delivers container location information (e-Slips) directly to drivers’ mobile devices. This enables ODCY-bound trucks to bypass the physical gate and proceed directly to their destination.
The project achieved rapid adoption, reaching an 86% utilization rate within four months of launch, with more than 60,000 truck movements processed through the system. BPA estimates that the solution avoids approximately USD 1 million in physical gate construction costs, reduces truck travel distance by 50% (from 2 km to 1 km per trip), and lowers annual fuel costs by approximately USD 66,000. The project has also improved traffic flow around the terminal, reduced driver waiting times, and mitigated congestion affecting nearby urban roads.
The Virtual Gate System has demonstrated strong scalability beyond its initial deployment. Following its proven success, a container terminal in Busan Port requested the integration of BPA’s geofencing and direction-vector technologies into its existing gate system, and deployment is currently underway. BPA plans to expand the solution to additional terminals, while its software-based architecture, low infrastructure requirements, and adaptability make it a highly replicable smart-port solution with strong potential for adoption and benchmarking by ports worldwide.
