Our key drivers of Innovation : Research & Development

Over the past three years on average, STraffic has demonstrated its unwavering commitment to innovation by investing 5% of its annual revenues into research and development. This bold investment fuels a dynamic R&D team that thrives on creativity and collaboration. Our roots trace back to 1991, when Samsung Electronics first pioneered the road business. The very engineers who began that journey continue to drive STraffic forward today, bringing decades of hands-on expertise and a proven track record of excellence.

With this unique blend of heritage and forward-looking vision, STraffic’s research teams embody both experience and ingenuity. They are not only seasoned professionals but also innovators who know how to transform ideas into groundbreaking solutions. This powerful combination ensures that STraffic remains at the forefront of smart mobility and infrastructure technologies, delivering value and pioneering advancements for clients worldwide.

Road Transportation

STraffic’s toll collection solutions, built on decades of engineering expertise, combine reliability, scalability, and innovation. With strong R&D investment and collaboration with global partners, STraffic delivers systems that not only streamline toll operations but also enhance the driver experience through convenience and speed.

1. TCS(Toll Collection System)

A toll collection system is an advanced infrastructure solution designed to automatically collect road usage fees from vehicles traveling on highways, expressways, or bridges. Modern systems use technologies such as RFID tags, smart cards, license plate recognition, and mobile payment platforms to ensure seamless and efficient transactions. By eliminating the need for manual toll booths, these systems reduce traffic congestion, minimize travel time, and improve overall road safety. They also provide operators with accurate, real-time data for traffic management and revenue tracking.

3. Multi-Lane-Free-Flow(MLFF)

The system provides differentiated service(1. Handling of multi lane communication and vehicles in violation by one lane controller, 2. Continuous operation with redundancy system) by using wireless communication(DSRC) in Multi-lanes instead of physically islanded toll booth Drivers do not need to drive in specific lanes to pay his/her fare to Use the ETCS system, instead, they can enjoy the free flow of driving.

ETCS by RFID with ISO 18006C (2019)
Overhead type Vehicle Detector (2021)
Overhead type ANPR (2022)

4. Cooperative-ITS (C-ITS)

The system allows drivers on the road to use road safer with WAVE communication technology.
By using WAVE communication technology, mutual interactions between the cars, cars and RSE(Road Side Equipment), or cars and portable personal devices is possible. Additionally, traffic information, such as traffic information, emergency conditions, and traffic flow information can be exchanged in real time.

Rail Transportation

STraffic’s train control system is built on a legacy of excellence that began in 1993, when Samsung Electronics established its Railway Business Division. From those early days, the same dedicated researchers and engineers have continuously advanced their expertise, collaborating with STraffic since its founding.
This long-standing partnership has enabled STraffic to deliver reliable and innovative train control solutions for both high-speed rail and urban transit systems. By combining decades of practical experience with cutting-edge technology, STraffic ensures safe, efficient, and intelligent railway operations that meet the evolving demands of modern transportation.

Korean Train Control System ST-KMX

ST-KMX, which was granted SIL-4 certification, STraffic Urban Railway TCS, was a wireless signaling system in the ILSAN Line project. It successfully worked and verified its reliability and performance. Thanks to this reference, we could lay a basis for unmanned infrastructure and a Korean TCS. ST-KMX is a wireless-based urban railway TCS that meets Korean Railway and RAMS standards. The Korean CBTC is a wireless-based TCS that uses WIFI or LTE-R to send real-time information.

AFC System

STraffic’s AFC System builds on the legacy of Samsung SDS, which implemented metro AFC systems in Seoul, Busan, and Daegu during the late 1990s and early 2000s. In 2001, Samsung SDS entered the Chinese market by winning the Guangzhou Metro AFC project, completing it in 2003 despite the SARS crisis, and later expanding to multiple lines to achieve a 40% market share in China by 2006. In 2010, the company secured a major AFC contract for Chengdu Metro Line 2 worth, overcoming local competition with superior technology. The experienced teams behind these projects joined STraffic at its spin-off in 2013, carrying forward their expertise to expand AFC and Smart Tolling businesses both domestically and internationally.
