Roundabout Video Analysis

Roundabout Video Analysis gives transport planners a smart, accurate, and comprehensive way to study how traffic really behaves at circular intersections. It helps identify hidden problems, improve designs, and create safer and more efficient traffic systems.

What is Roundabout Video Analysis?

Roundabout Video Analysis is a traffic monitoring technique that uses video recordings to study vehicle and pedestrian behavior at roundabouts. The footage is later analyzed to gather data such as traffic volume, turning movements, gap acceptance, delay time, and conflict points.

This method is more accurate than manual counting and provides visual evidence to support design or safety improvements.

Why Analyze Roundabout Traffic?

Roundabouts are designed to improve traffic flow and reduce accidents. But if they’re not working as expected, analyzing traffic behavior helps answer questions like:

Are drivers yielding properly?
Are any arms of the roundabout overloaded?
Are large vehicles struggling with the turn radius?
Are pedestrians or cyclists at risk?

The answers guide better engineering decisions and improve road safety.

Key Parameters Captured

A roundabout video analysis typically records:

Entry and exit volumes from each approach
Turning movements (left, through, right)
Vehicle classification (car, bike, truck, bus, etc.)
Queue lengths and delay times
Conflict points or near-miss events
Pedestrian and NMU activity
Circulating flow and gap acceptance behavior

Benefits of Using Video Analysis at Roundabouts

✅ Non-intrusive method: No need to install equipment on roads
✅ 24/7 recording: Day and night coverage
✅ Accurate vehicle tracking
✅ Behavioral insights: Real footage shows real actions
✅ Visual proof for authorities and stakeholders
✅ Safety assessments: Identify conflict zones and risky driver behavior

How the Video Analysis is Conducted

Step 1: Setup

Cameras are mounted on poles or buildings near the roundabout
Ideal height: 5–8 meters for a wide-angle view
Minimum duration: 12 to 24 hours of continuous footage

Step 2: Data Extraction

Analysts or AI-based software reviews the footage
Every vehicle’s entry, exit, and turn movement is recorded
Vehicle types and timestamps are also noted

Step 3: Reporting

Data is compiled into tables, heatmaps, charts, and diagrams
Summary includes peak hour analysis, congestion points, and suggestions for improvement

Use Cases and Applications

Traffic signal design or adjustments
Capacity and geometric analysis of the roundabout
Road safety audits
Planning for heavy vehicle movement
Pedestrian crossing evaluations
Pre/post construction performance comparison
Simulation model calibration (using real movement data)

Challenges and Considerations

Obstructed view due to trees, poles, or low camera placement
Weather issues (rain or fog) can reduce video clarity
Nighttime analysis may require IR-capable cameras
Manual video review is time-consuming if AI tools are not used
Data privacy concerns in public recording (depending on location laws)
