交通壅塞監測

Introduction In the era of rapid urbanization, traffic congestion has become a significant challenge for municipality managers and city planners. Gridlock not only leads to economic losses through delayed logistics and wasted fuel but also increases the risk of road accidents and environmental pollution. Traditional methods of traffic monitoring, such as inductive loops or manual observation, are often expensive to maintain and lack the intelligence needed for modern "Smart City" initiatives. ACTi’s Traffic Congestion Monitoring solution leverages AI-powered video analytics and a centralized management platform to provide real-time visibility into road conditions, allowing authorities to optimize traffic flow and respond instantly to bottlenecks.

Common Challenges

Inefficiency of Traditional Sensors: Physical sensors embedded in the road are difficult to install, prone to damage during roadwork, and cannot classify different types of vehicles.

Lack of Real-Time Intelligence: Relying on manual monitoring of video feeds is labor-intensive and often results in delays in identifying the onset of a traffic jam.

Environmental and Lighting Obstacles: Headlight glare, heavy rain, and nighttime conditions can reduce the accuracy of standard traffic cameras, leading to missed detections.

Difficulty in Queue Management: Identifying exactly when and where a queue starts at an intersection is critical for adjusting signal timing, yet this is difficult to achieve without automated measurement.

Fragmented Data Sources: Traffic data is often siloed, making it difficult for city departments to share information and coordinate a unified response to major congestion events.

ACTi Solution: AI-Driven Traffic Intelligence ACTi provides an end-to-end intelligent traffic surveillance solution that automates the detection of congestion and provides actionable data for urban mobility management.

AI-Based Queue Length Detection: ACTi’s AI-powered cameras can monitor specific lanes at intersections to measure queue length in real-time. If the number of vehicles or the wait time exceeds a predefined threshold, the system automatically triggers an alert.

Vehicle Counting and Classification: Beyond simple motion detection, ACTi’s deep learning analytics can distinguish between cars, buses, trucks, and motorcycles. This data is essential for understanding road load and planning long-term infrastructure improvements.

Real-Time Congestion Alerts: The ACTi Video Management System (VMS) serves as a command center, providing instant visual notifications when traffic slows down or stops in high-speed zones. Alerts can be sent via mobile push notifications or email to traffic controllers.

High-Performance Imaging for Challenging Environments: Equipped with High-speed Shutter technology and Extreme WDR, ACTi cameras deliver clear images despite blinding headlights or harsh weather, ensuring the reliability of the analytics 24/7.

Interactive E-Maps for City-Wide Visibility: ACTi’s VMS integrates an interactive map interface that displays the status of every monitoring point. Areas experiencing heavy congestion are highlighted, allowing operators to see the "big picture" of city traffic at a glance.

Traffic Pattern Analysis and Reporting: The system stores historical traffic data, enabling administrators to generate reports on peak congestion hours and seasonal trends. This metadata-driven approach supports evidence-based decisions for signal timing and road expansion.

Conclusion ACTi’s Traffic Congestion Monitoring solution transforms standard surveillance into a proactive management tool. By providing automated detection and deep analytical insights, ACTi empowers city authorities to reduce travel times, improve road safety, and enhance the overall quality of life for citizens through smarter, data-driven traffic management.
