Project Overview
The Quy Nhon – Chi Thanh sub-project is part of the North–South Expressway East Project, covering the deployment of display and traffic information systems (ITS). This is one of the key initiatives aimed at modernizing the management, operation, and utilization of Vietnam’s national arterial expressway.
With significant route length and projected high traffic volume, the investor required an integrated solution encompassing a large-scale display system at the IOC (Integrated Operations Center) and a network of Variable Message Signs (VMS) along the route, compliant with the European EN12966 standard.
Customer Requirements
The investor set forth demanding and comprehensive technical requirements:
- Large-scale IOC: The display system at the operations center had to monitor the entire expressway route, seamlessly integrating data from CCTV cameras, ITS systems, and other operational information sources.
- Display quality and stability: High resolution, seamless imagery, 24/7 continuous operation stability, and easy content management and customization were required.
- VMS network along the route: High-density deployment of electronic signage to support traffic regulation and real-time incident warnings.
- International standard compliance: All VMS signs had to meet the EN12966 standard, ensuring clear visibility under all outdoor conditions — strong sunlight, rainstorms, and harsh weather.
- Multilingual support and centralized control: The system had to support multiple languages (including Vietnamese) and allow centralized control and monitoring from the IOC.
System Solution
The deployed solution was built around two core systems:
1. LCD Video Wall System at IOC
The central display system was designed on a large scale:
| Component | Specification |
|---|---|
| Number of screens | 80 LCD video wall panels |
| Bezel width | Ultra-narrow 0.88 mm |
Accompanying synchronized components:
- Dedicated video wall controller
- Centralized display management software
- Synchronized power and signal cabling system
Key features:
- Multi-source data display: CCTV footage, traffic maps, ITS device status, operational dashboards
- Flexible layout customization based on monitoring needs
- High stability, 24/7 continuous operation without interruption
- Full system synchronization from hardware to management software
The Video Wall system serves as the visual nerve center, enabling the operations team to observe the entire expressway and make timely operational decisions.
2. VMS Traffic Sign System (EN12966)
The VMS network was deployed along the route with diverse types and density:
| Sign Type | Quantity | Dimensions |
|---|---|---|
| VMS P20 | 20 signs | 7.68 m × 1.28 m |
| VMS P10 | 40 signs | 1.28 m × 1.28 m |
| VMS P10 | 2 signs | 3.84 m × 1.28 m |
Outstanding technical features:
- EN12966 compliant — ensuring quality and reliability per European standards
- High-brightness LED technology, clearly visible even under direct sunlight
- Wide viewing angle, easy visibility from distance and at high speeds
Operational features:
- Real-time traffic information display
- Incident warnings, accident alerts, and flexible traffic regulation
- Multilingual support (Vietnamese and other languages)
- Remote content and brightness adjustment from the IOC
- Real-time status monitoring of each individual sign
The VMS system enables rapid, direct information delivery to road users along the entire route, effectively enhancing awareness and regulating vehicle flow.
Implementation Process
The project followed a methodical five-step process:
- Site survey: Assessment of installation locations along the route and at key interchanges
- System design: Solution optimization to suit actual terrain and infrastructure conditions
- Installation and integration: Equipment installation, connection of the Video Wall system and the entire VMS network
- Configuration and testing: Management software setup, system configuration, comprehensive operational testing
- Acceptance and handover: Quality inspection, technical requirements verification, and system handover for operation
The entire construction process strictly complied with occupational safety and fire prevention regulations, as well as technical standards of the transportation industry.
Project Results
Upon completion and operational deployment, the system delivered tangible value:
- Real-time traffic monitoring and management across the entire route: The operations team can instantly grasp traffic conditions throughout the expressway from the IOC.
- Centralized, visual display: The 80-screen Video Wall with ultra-narrow bezels provides a seamless visual experience, effectively supporting monitoring and command briefings.
- Timely information delivery to drivers: The dense VMS network along the route enables rapid, accurate transmission of traffic conditions, hazard warnings, and route guidance to road users.
- Enhanced traffic safety: Proactive early warning and traffic regulation capabilities contribute to reducing accidents and congestion on the expressway.
- Optimized expressway utilization efficiency: Streamlined operations, reduced incident response time, and improved user experience.
- Future-ready expansion: The system features an open architecture, facilitating easy integration and expansion with other ITS systems in subsequent development phases of the North–South Expressway.
