On May 7, 2024, Project Management Board (PMU) 7 visited the Cam Lam - Vinh Hao expressway project to exchange experiences in implementing and managing the Intelligent traffic system (ITS) and electronic toll collection system (ETC).
Under the Ministry of Transport's directive, PMU 7 oversees the implementation of ITS, ETC systems, and vehicle load inspection stations along the East North-South Expressway. Amidst the implementation, new challenges emerged, necessitating knowledge exchange on technology, equipment, and operational management. Consequently, PMU 7 enlisted Deo Ca Group for collaborative support and expertise exchange.
The delegation of PMU 7 visited the Cam Lam - Vinh Hao Expressway Operation Management Center
The newly inaugurated Cam Lam - Vinh Hao Expressway, opened on April 28, 2024, stands as the sole Phase 1 North-South expressway project equipped with an advanced ITS system, seamlessly integrating road and Nui Vung tunnel functions. Its inter-line ETC system features barrier-free entry, while toll collection data is seamlessly synchronized with the Toll Collection Monitoring Center, ensuring transparent toll operations. Notably, clusters of ITS equipment operate on renewable energy sources such as solar batteries and wind turbines, with remote monitoring capabilities for prompt troubleshooting via an internal transmission system.

Mr. Duong Chau Sam, Deputy General Director of Deo Ca Group, outlined the comprehensive components of the ITS system on the Cam Lam - Vinh Hao expressway, encompassing electrical systems, ventilation, fire protection, lighting, CCTV for incident detection, electronic traffic signs, signal lights, and the ETC toll collection system. Notably, the CCTV network comprises 21 PTZ, 1 FIX, and 5 VDS stationed every 2 kilometers along the route to gather and relay route information to the control center.
Along the route, the 2,250m-long Vung Mountain tunnel is classified as a special-level tunnel, featuring an ITS system comprising 11 PTZ, 38 FIX, and 4 VDS cameras for monitoring and data collection. These systems promptly relay warnings to the operational center. Mr. Sam highlighted the provision of emergency telephone, FM, and radio systems within tunnels over 500m in length to ensure uninterrupted communication and problem-solving for operational management.

The traffic monitoring and operations center integrates signals from tunnel and route peripheral devices (CCTV, VMS, sensors, etc.) to devise timely safety measures. Additionally, it leverages artificial intelligence (AI) for situation analysis, aiding traffic supervisors in making informed decisions during incidents.
Currently, Vung Mountain tunnel is the only tunnel eligible for acceptance of fire protection if according to TCVN 13878:2023 on fire protection for road tunnels (new standard issued in 2023).
Phase 1 of the project includes a single, two-way circulation tunnel at Vung Mountain. Deo Ca Group has suggested an investment plan to complete and activate both tunnels, each accommodating one-way traffic with three lanes, ensuring safety and maximizing investment efficiency.
Deo Ca Group's operational experience at Hai Van Tunnel demonstrates a remarkable increase in visibility by 85% - 95% and a substantial decrease in traffic incidents from an average of 3,817 cases/year to just 585 cases/year after both tunnel pipes were activated. Additionally, operating both tunnels reduces electricity consumption by 30% - 40% due to limited fan usage in well-ventilated conditions.
Deo Ca boasts nearly a decade of experience in managing and operating the ITS system since the inception of the Deo Ca Tunnel Operation Center. With extensive practical experience and a comprehensive investment approach from the outset, Deo Ca currently maintains and manages a data system for Deo Ca, Cu Mong, and Hai Van tunnels, collecting, storing, and analyzing traffic data at ITS-ME data centers.
While tunnel projects on the North-South Expressway only invest in mechanical and electrical systems, Deo Ca Group's projects (Deo Ca, Cu Mong, Hai Van, Nui Vung tunnels) include synchronized investments in both M&E systems (comprising 5-7 components) and ITS systems (comprising 10-12 technology components). This makes Deo Ca Group a trailblazer in smart traffic technology, ensuring utmost safety and smooth traffic flow.
