CATI LawRoad Safety and Traffic Accidents — Technology solution for its implementation
The CATI Law requires electronic enforcement of traffic violations with certified photographic evidence. Visionaria delivers the complete platform — hardware, software and operation — on new infrastructure or on assets already under our maintenance.
Regulatory framework
What does the CATI Law require?
Law 21.495 on Road Safety and Traffic Accidents sets a new standard for traffic enforcement in Chile, making technology the core of violation detection and recording. Its phased rollout opens a critical window for municipalities, traffic agencies and highway concessionaires.
- Mandatory electronic traffic enforcement on concessioned highways and high-congestion urban roads
- Automated violation recording with photographic evidence valid before the Local Police Court
- Interoperability with the National Violations Registry of the Ministry of Transport (SEMTT)
- Phased rollout: communes prioritized by CONASET's road-accident rate index

Detection capabilities
Violations the system records automatically
Every event generates a record with image, plate, speed or violation type, timestamp and coordinates — evidence valid for notification and proceedings before the Local Police Court.
Speeding
Integrated 60 GHz radar measures instantaneous speed with ±2 km/h accuracy. Photo capture of the vehicle, plate and speed in a single violation record.
Red light violation
Linked to the traffic signal controller via RS485/dry contact. The system records the crossing while the signal is red, with vehicle image and synchronized timestamp.
Misuse of exclusive lanes
Detects vehicles in bus/metro lanes, emergency lanes or segregated corridors via Specific Lane Management, scheduled or permanent.
Wrong-way driving
Automatic Reverse Driving Detection for travel against the permitted direction. Generates an immediate alert and record with image and plate.
Vehicle without a visible plate
Identifies vehicles circulating without a plate or with a tampered plate (No-plate Vehicle Capture). High-resolution image recorded as evidence.
Flow statistics and classification
Counts by vehicle type (car, motorcycle, truck, bus), average speed and hourly distribution. Data for road planning and compliance assessment.
Certified hardware
Two options for every scenario
Same software architecture, same management platform. The unit is chosen based on road type, number of lanes and operating speed.

Implementation model
Enforcement as a service
Visionaria operates over 300 LPR points in the Santiago Metropolitan Region. That installed infrastructure is the foundation for rolling out CATI enforcement without starting from scratch.
Upgrade on existing infrastructure
If you already operate LPR cameras under a maintenance contract with Visionaria, we add enforcement capabilities on top of the installed network: firmware updates, integration with traffic signal controllers and activation of violation-detection modules.
New sites · Concession model
Visionaria finances, installs and operates the equipment. The municipality or public agency receives a fully working system and violation reports with no upfront cost. The recovery model is structured on the processed violation records.
Enforcement platform as a service
Violation records generated by the system feed directly into the municipality's or SEMTT's violation-management platform. Reports, photographic evidence and flow data available via API and web portal.
Native integration
Builds on what's already there
The CATI module integrates on top of Visionaria's LPR/ANPR platform. Violation records share the same database as SEBV alerts and SITIA events — the operator manages everything from a single console.
- Violation image + plate + speed in a single ticket
- Automatic export in the format required by SEMTT
- Checkpoint monitoring dashboard with real-time compliance rate
- Automatic reports by segment, time window and violation type
- Photographic evidence stored with a cryptographic hash for legal validity
Flow of a violation event
Capture
Radar detects speed · camera records a high-resolution image with the plate
Recognition
OCR engine identifies the plate in <500 ms · associated vehicle attributes
Validation
System checks against configured thresholds (speed, lane, signal)
Recording
Ticket generated with evidence, hash and metadata · stored locally and on the central platform
Notification
Alert to the operator · export to the municipal or SEMTT violation-management system
