About S Traffic

Established in January 2013, S Traffic Co., Ltd. operates as a specialized provider of integrated transportation system solutions in South Korea. The company originated from the road transportation business division of Samsung Electronics, which began in 1991, and was later spun off from Samsung SDS. This heritage provides the firm with a deep well of experience, with over 45% of its employees possessing more than two decades in the industry. The company went public, listing on the KOSDAQ on December 5, 2017.

S Traffic is structured into two primary business segments: road and railway. For the road transportation sector, the company develops, manufactures, and installs intelligent transportation systems (ITS), toll fare collection systems, and multi-lane free-flow systems that allow for automated charging without requiring vehicles to stop. Its offerings for the railway industry include advanced signaling systems, communication-based train control (CBTC), and railway communication platforms. These systems manage critical functions such as operations monitoring, passenger information dissemination, and onboard communications. The company's business model is centered on the development, manufacturing, distribution, installation, and maintenance of these hardware and software solutions for transport operators.

The firm serves a range of clients both domestically in South Korea and in overseas markets. Key domestic clients include the Korea Expressway Corporation, Korea Rail Network Authority, and Seoul Metro. S Traffic has expanded its global footprint with projects such as an automatic fare collection (AFC) system for the Delhi Metro and toll collection systems in Azerbaijan and Bangladesh. To support these international operations, the company has established subsidiaries in the US and India. As of the trailing twelve months ending March 31, 2025, S Traffic reported revenues of $145 million. A significant milestone includes the development of key IT systems for Incheon International Airport's fourth phase of expansion.
