The document describes several smart transportation solutions implemented by CENTIOS in South Korea: 1. An Advanced Traffic Management System (ATMS) that collects traffic data from sensors and cameras and provides information to drivers through variable message signs and an traffic information center. 2. An Automated Traffic Signal Control System (ATSCS) that adjusts traffic light timing in real-time based on vehicle detection systems at intersections. 3. A Bus Information/Management System (BIS/BMS) that provides bus schedule and routing information to drivers and passengers through on-board units and displays at bus stops. 4. A Bus Rapid Transit (BRT) system that has increased transit speeds and citizen satisfaction on
