Ruta 27 is the busiest motorway in Costa Rica, connecting the Capital of San Jose to the pacific coast.

This 50-mile toll road sees as much as 200,000 AADV and 1,000 accidents per year. These incidents caused harm to road users, posed a risk to road workerс who attended them, and would result in congestion and lost revenues. The road operator worked with Valerann to deploy a solution that would help improve safety on the road and help keep traffic flow smooth.

“By having early road incidents notification, we are able to shorten our response time.”
– Andres Viveros, Operations Director,Ruta 27

Using Lanternn by Valerann™, the Ruta 27 team were able to detect up to 80 additional true and relevant safety events per day. Of these, 35% received initial response within 4 minutes

During system usage traffic flow increased by 6% and accidents with injuries and fatalities decreased by 10% per 100K vehicles.

Ruta 27 together with Valerann deployed Lanternn by Valerann™ into the Ruta 27 Control Center.

The system integrated with 50 CCTV cameras, patrol vehicles, Google Maps, data from the toll booths, as well as weather data.

‍
The system used machine vision, data fusion and AI to sift through over 20,000 data points a day and surface only the 80 most relevant events to the control center. The alerts were coupled with contextual data and historical video footage for rapid validation. The combination of prioritized alerting and rapid validation was used to expedite response in an effort to prevent crashes and reduce their impact. As part of the effort, Lanternn was integrated with the road’s existing ATMS. So, when an incident was validated, operators used automated response workflows, directly from LbV to manage it.
