Towards more sustainable transportation

In Chile, Vehicle Technical Inspection Facilities use license plate recognition technology to improve service times and help reduce vehicle emissions

“The video system supports us both in terms of safety and in terms of vehicle license plate recognition and monitoring each step of the inspection process. This allows us to provide a highly efficient service.” Cristian Rojas Stuardo, Information Technology and Telecommunications Manager for Chilena de Revisiones Técnicas SPA.


CHRT (Chilena de Revisiones Técnicas)—a service provider that operates some of Chile’s Technical Inspection Facilities—was faced with the challenge of modernizing how it carries out the entire vehicle administrative and control process. It needed to do so as a result of a rule that the Ministry of Transportation imposed on whatever service provider won the concession contract, requiring the winning bidder to incorporate technology for different types of services and offer them in a way that was faster, technology-driven, and more cost-effective.


In response to this requirement, CHRT chose a system that includes several Axis network cameras, according to the different needs and uses in each area of the company’s facilities. After each vehicle arrives at the facility, License Plate Recognition (LPR) analytics technology enables the entire inspection process to be completed much more efficiently. While some vehicles move forward through the technical part of the review, others can start with the first steps of the administrative procedure, which involves documentation. This ensures optimal response time for the service.


The image quality of the cameras and the analytics used in this project have resulted in a notable improvement in service at the inspection facilities. Shorter processing times are a key aspect of this. Previously, the process was estimated to require an average of 5 hours, while today it takes only about 40 minutes. Logistics for the process were optimized, making it more dynamic and improving the efficiency of operators responsible for evaluations. As a result, a higher percentage of cars are in compliance with this requirement, which has made a positive impact on the environment and avoided sanctions.
