Case Name: 

The Intelligent Traffic Signal Control Optimization System in Fuzhou City

Location:

Yingbin Avenue, Nanmen Road, and Menghudan in Fuzhou City

Benefit:

ClairWav Radars help the traffic control system realize accurate measurement, fast calculation, and optimal control. 

Key Features:

1. Real-time adaptive control single points. 

• The system automatically adjusts the signal cycle more than 600 times a day on average, with a change rate more than 110 times that of fixed configuration schemes.
• This essentially eliminates phenomena such as empty releases and secondary stops at intersections, significantly improving the traffic efficiency at road intersections.

2. Dynamic arterial coordination

• Enabling real-time data communication and interaction between intersections along the road. 
• It adjusts the arterial coordination cycle in real-time based on traffic conditions, achieving the effect of dynamic green wave progression.

3. Regional intelligent coordination 

• It adjusts the traffic conditions at various intersections within the region from the inside out, ultimately achieving the goal of real-time optimization of regional traffic signals.

Improvements:

The average number of secondary stops at intersections is reduced by approximately 1,680 vehicles per hour, and the average hourly traffic volume at intersections can increase by about 8% compared to the original baseline. The average congestion time at intersections during peak hours is reduced by 43.5%, with a 44.9% reduction during the morning peak and a 43.1% reduction during the evening peak.
