​Digital Transformation and Innovation of Traffic Operations Management Completed with 'Traffic Digital Twin Platform'

As the fourth industrial revolution technology, information and communication (ICT), big data, artificial intelligence (AI), and SW technologies are constantly developing. The convergence of single technologies has opened the era of full-fledged hyper-intelligence, connection, virtualization, and intelligence, and the use of digital twin technology that reinforces visualization in three dimensions is expanding significantly across all industries.

Metabuild has been recognized for its excellence by commercializing its own middleware technology (MESIM ESB/IoT/APIG/mHUB) for 25 years to solve the limitations of the existing traffic management system. To solve the problem, Metabuild used middleware technology, radar technology (Smart IDS/VDS), big data technology (MESIM DataHUB), artificial intelligence platform technology (MAI AUTO), and visualization technology (TRAFFIC TWIN) for the first time in the transportation field.

In order to overcome the limitations of roof sensors and video cameras of existing traffic management systems, Smart IDS/VDS products, which were researched and commercialized for the first time in the world, have patented a radar system that can detect cars and pedestrians on the road from hundreds of meters to 1 kilometer, and have been recognized for their excellent technology that it has been supplied to 2,000 sections in Korea and abroad. It is being used in a system that collects traffic information and emergency situation information within a specific road section in the recently established national highway ITS and next-generation transportation system (C-ITS) projects.

Using Metabuild's Smart IDS/VDS, it operates as a digital twin-based transportation integrated platform that detects and provides driving speed and location data of vehicles driving on the road, as well as unexpected situations such as accidents and road obstacles in real time.

Metabuild's data connection and integration(MESIM ESB/IoT/APIG/mHUB) products collect on-site data collected from radar systems, traffic sensors, weather sensors, and CCTV installed and operated at road sites in real time, and are used to link various information such as construction information, weather information, and accident information managed by other systems.

Data collected in real time through the traffic digital twin platform can be stored and managed in MESIM DataHUB, and the location and speed of vehicles running on the digital road based on a precise map corresponding to the road in the target section, as well as accident and unexpected situation information, can be used in real time to implement the same traffic flow in the digital twin.

The information accumulated in the digital twin can be used for traffic operation and management through various statistical analysis, simulation, and AI models through the artificial intelligence platform. In addition to the data collected in the road infrastructure, the actual traffic flow is provided as a digital twin using data such as the location, speed, acceleration, and deceleration of the vehicle collected through the C-ITS wireless communication terminal (OBU) installed in the vehicle.

Metabuild has grown into the No. 1 company in middleware SW since its foundation in 1998, and since 2008, it has developed and commercialized a radar-based emergency situation detection system through the smart highway project of the Ministry of Land, Infrastructure and Transport, drawing attention in earnest in the transportation business. Metabuild is growing with the goal of developing next-generation traffic control and operation technology by converging radar technology and SW technology. Its traffic detection system will be commercialized as a traffic digital twin flat by installing AI platform and linkage SW.

For example, many types of roads such as the Korea Expressway Corporation's Seohae Bridge, Gyeongbu Expressway, Jaeyaksan Tunnel, National Road, and Incheon Airport Highway are using real-time integrated traffic control platform and response to unexpected situations through the transportation digital twin platform developed and supplied by Metabuild. Recently, a digital twin-based autonomous vehicle control platform has been established and operated in Daegu 5G autonomous driving test road and Saemangeum commercial autonomous driving testbed project.

Metabuild has been researching, developing and supplying digital twin platforms not only in the transportation sector, but also in various fields such as construction equipment and processes, urban structures, air quality, energy, buildings, and drones, and will continue to work to ensure that digital twin technology can be applied to more fields.

It plans to apply various visualization technologies to implement real objects as digital objects and develop the data accumulated on the digital twin platform into a technology that finally implements the metaverse by connecting the virtual and real worlds such as various cognition, judgment, prediction, decision-making, and autonomous control through artificial intelligence models and learning.​
