Client: Anhui Transportation Holding Group Co., Ltd.
Industry: Highway Traffic Management & Intelligent Transportation Systems (ITS)
Solution: SyncTimeHub NTP Time Server for Interval Speed Monitoring Accuracy
With the rapid growth of China’s transportation infrastructure, intelligent highway management has become an essential pillar for modern smart traffic systems. Anhui Transportation Holding Group, a key operator of the province’s highway network, is responsible for large-scale construction, operation, and service management across multiple expressways.
To improve traffic monitoring accuracy—especially in applications involving interval speed measurement and real-time event recording—the Group required a highly reliable, unified, and precise time synchronization system. SyncTimeHub’s NTP Time Server Solution was selected as the technical foundation for this upgrade.
Anhui's highway surveillance network spans multiple cities, tunnels, toll stations, and service points, with monitoring devices operating at wide physical distances. This creates a critical challenge:
| Requirement | Reason |
|---|---|
| Unified standard time | Prevent inconsistent time stamps across cameras and detection points |
| Microscale precision | Interval speed calculations require extremely accurate timing to avoid measurement errors |
| Stable continuous operation | Systems must run 24/7 with no allowance for drift or downtime |
| Secure communication | Critical monitoring data requires protected and authenticated timestamps |
SHUTAI's solution addressed all these needs with high precision and industrial-grade reliability.
SHUTAI NTP Time Server receives time from:
GPS and BeiDou satellite systems
UTC standard reference sources
Multiple redundant signal paths for failover stability
It then distributes synchronized time across the expressway network through the highway monitoring system to ensure all front-end devices operate on an identical timestamp.
| Feature | Benefit |
|---|---|
| Millisecond to microsecond-level accuracy | Ensures lawful and traceable speed and violation recordings |
| Wide-protocol support | Compatible with cameras, radar sensors, traffic controllers & VMS platforms |
| Built-in security firewall & log auditing | Protects data integrity and prevents unauthorized access |
| Modular architecture | Easier maintenance, upgrades, and long-term scalability |
After deployment, Anhui Transportation Holding Group achieved measurable improvements:
All video and radar detection points now record data with unified timing—guaranteeing accurate vehicle travel-time comparison and legal reliability in violation evidence.
With devices synchronized to a standard source, the system responds faster to violations, congestion, accidents, and emergency incidents.
Automatic synchronization eliminates the need for manual calibration, reducing technician workload and system downtime.
Embedded protection mechanisms (firewall, audit logs, anti-tamper functions) ensure trustworthy data for law enforcement and traffic safety operations.
✔ Reliable timing for high-accuracy interval speed measurement
✔ Higher enforcement credibility in violation evidence records
✔ Better coordination between surveillance nodes and the traffic control center
✔ Lower lifetime operating and maintenance costs
✔ Supports digital highway and smart transportation development goals
By adopting the SyncTimeHub NTP Time Server, Anhui Transportation Holding Group significantly improved the precision, security, and efficiency of its highway monitoring network. This upgrade strengthens the foundation for intelligent highway operation and provides safer, more reliable travel conditions for drivers across the province.
