Introduction

  • Managing traffic across a large road network requires more than conventional CCTV surveillance. Traffic authorities need continuous visibility, automated violation detection, accurate vehicle identification, reliable speed monitoring and quick access to incident evidence.
  • Katomaran Technologies implemented an AI-powered Traffic Management System across approximately 40 km in Theni district, Tamil Nadu. The project integrated 33 strategically positioned cameras across major transport hubs, administrative areas, bypass roads and high-traffic junctions.
  • The solution combined AI video analytics, Automatic Number Plate Recognition, sectional speed measurement, vehicle tracking, traffic violation detection, incident monitoring and centralized video management.
  • Instead of using cameras only to record road activity, the system continuously analyzed traffic footage and generated actionable events whenever a configured violation, vehicle or incident was detected.
  • This transformed the camera network into an intelligent traffic monitoring platform capable of supporting traffic enforcement, road safety and data-driven traffic management.

Key Traffic Monitoring Locations

  • The 33-camera network was deployed across strategically important locations within Theni district.
  • The major monitoring points included:
  • 1
    Theni Bus Stand
  • 2
    Theni District Collectorate
  • 3
    Cumbum Bypass Junction
  • 4
    Vilakku Junction
  • 5
    Gandhi Statue Junction
  • 6
    Annaji Junction
  • 7
    Thappukundu Junction
  • 8
    Vadugapatti Junction
  • 9
    Chinnamanur Junction

These locations represented a combination of busy public transport areas, administrative zones, important junctions, bypass connections and road entry and exit points.

Each camera location was planned according to its traffic environment and monitoring objective. Some cameras focused on number plate recognition and vehicle movement, while others supported violation detection, traffic observation, incident identification or sectional speed measurement.

Connecting all these locations to one centralized platform provided traffic operators with unified visibility across the entire monitored corridor

The Traffic Management Challenge

  • Monitoring a 40 km road corridor manually creates significant operational challenges. The road network includes varying traffic conditions, vehicle speeds, road layouts and movement patterns. Busy junctions may experience congestion and traffic violations, while open road sections require speed monitoring and incident detection. Even when CCTV cameras are available, operators cannot continuously observe every feed and identify every violation in real time.
  • The project needed to address several important requirements:
  • 1
    Monitor traffic activity across a long road corridor
  • 2
    Centralize video feeds from multiple locations
  • 3
    Detect traffic violations automatically
  • 4
    Identify vehicles using number plate information
  • 5
    Measure vehicle speed across selected road sections
  • 6
    Track vehicle movement between monitoring points
  • 7
    Detect accidents, stopped vehicles and road obstructions
  • 8
    Monitor traffic congestion and vehicle density
  • 9
    Count and classify different vehicle categories
  • 10
    Generate visual evidence for detected events
  • 11
    Reduce dependence on continuous manual observation
  • 12
    Maintain searchable traffic and vehicle records

The solution also needed to remain scalable so additional cameras, analytics and monitoring locations could be integrated in the future.

Katomaran Technologies’ Solution

  • Katomaran Technologies developed an integrated traffic monitoring solution built around its Intelligent Traffic Management System. The implementation began with an assessment of the road corridor, traffic patterns, junction layouts and critical monitoring requirements.
  • Camera locations and viewing angles were selected based on:
  • 1
    Road direction and lane visibility
  • 2
    Vehicle approach and departure paths
  • 3
    Number plate capture requirements
  • 4
    Distance between speed-monitoring points
  • 5
    Traffic density at junctions
  • 6
    Available installation infrastructure
  • 7
    Required AI detection capabilities

The 33 cameras were then integrated into a centralized monitoring environment. AI analytics were configured according to the operational purpose of each camera. The complete solution included: AI-powered video analytics, Automatic Number Plate Recognition, sectional speed measurement, vehicle tracking, traffic violation analytics, and Centralized live video monitoring. This integrated approach allowed the system to identify relevant traffic activity automatically instead of depending entirely on manual camera observation.

AI Video Analytics for Proactive Traffic Monitoring

  • AI video analytics formed a major part of the Theni Traffic Management System. The analytics engine processed live camera feeds and identified vehicles, traffic behaviour, violations and roadway incidents based on configured rules.
  • When the system detected a relevant event, it generated an alert containing available details such as:
  • 1
    Detection category
  • 2
    Camera name
  • 3
    Monitoring location
  • 4
    Event date and time
  • 5
    Vehicle image
  • 6
    Number plate image
  • 7
    Vehicle category
  • 8
    Direction of movement
  • 9
    Event snapshot
  • 10
    Supporting video clip

This allowed operators to focus on important events rather than continuously monitoring all 33 camera feeds. The system also helped transform unstructured CCTV footage into searchable and organized traffic information.

Sectional Speed Measurement

  • One of the key technologies used in the Theni project was sectional speed measurement. Unlike conventional point-based speed detection, which measures speed at one location, sectional speed measurement calculates a vehicle’s average speed between two predefined monitoring points. This method provides speed monitoring across a longer section of the road.
  • How Sectional Speed Measurement Works:
  • When a vehicle passes the first monitoring point, an ANPR-enabled camera captures the vehicle and records the vehicle number plate, entry date and time, entry camera location, vehicle image, and direction of travel. When the same vehicle reaches the second monitoring point, another camera captures the number plate and exit timestamp.
  • The Traffic Management System matches the number plate records from both locations. It then calculates the time taken by the vehicle to travel the known distance between the two camera points.
  • The sectional speed workflow follows this process:
  • Vehicle Detected at Entry Point → Number Plate Captured → Entry Time Recorded → Vehicle Detected at Exit Point → Number Plate Matched → Travel Time Calculated → Average Speed Determined → Violation Event Generated
  • When the calculated average speed exceeds the configured speed limit, the system generates an overspeeding event with entry/exit images, number plate crop, timestamps, and locations as supporting evidence.
  • Sectional speed measurement helps discourage drivers from slowing down only near individual speed cameras and accelerating again after passing them. It supports more consistent speed compliance across the monitored road section.

Automatic Number Plate Recognition

  • Automatic Number Plate Recognition was used to identify vehicles and convert registration plates into searchable digital records.
  • When a vehicle passed an ANPR-enabled camera, the system captured the vehicle image, detected the number plate and associated the record with the relevant location, date and time.
  • ANPR supported several important project workflows:
  • 1
    Sectional speed calculation
  • 2
    Vehicle entry and exit monitoring
  • 3
    Vehicle movement analysis
  • 4
    Searchable vehicle records
  • 5
    Violation evidence generation
  • 6
    Blacklisted or watchlisted vehicle alerts
  • 7
    Traffic pattern analysis
  • 8
    Historical vehicle searches

Operators could search for a vehicle using its registration number and review where and when it was identified within the monitored road network. Number plate information could also be connected with related images, event details and recorded video footage.

Traffic Violation Detection

Different AI analytics were configured according to camera location, road conditions and monitoring requirements.

1. Overspeeding Detection

Sectional speed measurement was used to calculate the average speed of vehicles across defined road sections and generate alerts when vehicles exceeded configured limits.

2. Wrong-Way Driving Detection

The system identified vehicles moving against the permitted traffic direction within configured road areas.

3. No-Helmet Detection

AI analytics detected two-wheeler riders travelling without the required protective helmet.

4. Triple-Riding Detection

The system identified motorcycles carrying more than the permitted number of riders.

5. Seatbelt Violation Detection

Cameras positioned for suitable vehicle visibility supported the detection of drivers or passengers not wearing seatbelts.

6. Mobile-Phone Usage Detection

The analytics system could identify drivers using mobile phones while operating a vehicle where camera positioning and image quality supported the detection.

7. Lane Violation Detection

Virtual road zones and lane rules were used to detect vehicles entering restricted lanes or moving outside permitted traffic paths.

8. Illegal Parking and Stopping

The system detected vehicles remaining within configured no-parking or restricted stopping areas beyond the permitted duration.

Not every detection needed to run on every camera. Analytics were applied according to each camera’s purpose, viewing angle and traffic environment.

Road Incident Detection

  • The Traffic Management System also supported the identification of events that could affect traffic flow and road safety.
  • These included:
  • 1
    Road accidents
  • 2
    Stopped vehicles
  • 3
    Vehicle breakdowns
  • 4
    Traffic congestion
  • 5
    Road obstructions
  • 6
    Unusual vehicle movement
  • 7
    Sudden changes in traffic flow
  • 8
    Vehicles remaining stationary in restricted areas

When an incident was detected, operators could verify the event using live or recorded video and coordinate an appropriate response. Faster incident visibility helped reduce the delay between an event occurring and the monitoring team becoming aware of it.

Vehicle Detection, Counting and Classification

  • In addition to violations and incidents, the platform provided traffic intelligence through vehicle detection and classification.
  • The system could detect and categorize vehicles into relevant groups, such as:
  • 1
    Two-wheelers
  • 2
    Cars
  • 3
    Auto-rickshaws
  • 4
    Light commercial vehicles
  • 5
    Buses
  • 6
    Trucks
  • 7
    Heavy commercial vehicles

Vehicle counting provided visibility into traffic movement across selected junctions and road sections.

The collected information could support:

  • 1
    Entry and exit vehicle counts
  • 2
    Direction-based traffic analysis
  • 3
    Vehicle category distribution
  • 4
    Traffic density monitoring
  • 5
    Peak traffic period identification
  • 6
    Junction movement analysis
  • 7
    Long-term traffic planning

This data helped move traffic monitoring beyond video surveillance by providing measurable insights into road usage.

Centralized Video Monitoring

  • All 33 cameras were connected to a centralized traffic monitoring environment.
  • Operators could access:
  • 1
    Live camera feeds
  • 2
    Recorded video
  • 3
    AI-generated alerts
  • 4
    ANPR records
  • 5
    Vehicle search results
  • 6
    Speed violation events
  • 7
    Traffic incident evidence
  • 8
    Camera health information
  • 9
    Event reports

Centralized monitoring removed the need to operate individual cameras through separate systems.

Operators could review multiple locations from a single interface, switch between live and recorded footage and verify detected events using supporting evidence.

This provided consistent monitoring across Theni Bus Stand, the District Collectorate, Cumbum Bypass Junction, Vilakku Junction, Gandhi Statue Junction, Annaji Junction, Thappukundu Junction, Vadugapatti Junction and Chinnamanur Junction.

Evidence and Event Management

  • For every detected violation or incident, the platform maintained available supporting evidence.
  • Depending on the event type, the evidence could include:
  • 1
    Vehicle overview image
  • 2
    Number plate crop
  • 3
    Event snapshot
  • 4
    Recorded video clip
  • 5
    Camera location
  • 6
    Detection date and time
  • 7
    Vehicle category
  • 8
    Direction of movement
  • 9
    Entry and exit timestamps
  • 10
    Measured average speed
  • 11
    Configured speed limit
  • 12
    Event verification status

This created a structured workflow for reviewing, verifying and retrieving traffic events.

Instead of manually searching through hours of recorded video, operators could locate relevant incidents using filters such as date, time, location, vehicle number or detection category.
