Video Surveillance System Protects Critical Traffic Tunnel

PureActiv Geospatial Video Analytics from PureTech Systems® have been installed to help protect the Tom Lantos Tunnels in the Devil's Slide area of San Mateo County, California.

PureActiv Geospatial Video Analytics from PureTech Systems® have been installed to help protect the Tom Lantos Tunnels in the Devil's Slide area of San Mateo County, California. The Tunnels, which officially opened in early 2013 to replace a rockslide-prone portion of State Route Highway 1 known as Devil's Slide, have been equipped with the company's PureActiv® video analytics capability to aid in the protection and safety monitoring of the tunnels.

Managed by Caltrans, which oversees more than 50,000 miles of California's highway and freeway lanes, the tunnels consist of a single northbound and a single southbound lane approximately 4,200 ft long and 30 ft wide. As part of the safety and security initiatives, the tunnels include a Bosch Video Management System (BVMS), MIC Series 612 Thermal and DINION cameras from Bosch, integrated with the PureActiv geospatial video analytics and map-based user display.

Tunnel Safety Plus Operational Data

The installation marks several firsts for PureTech Systems, including its first tunnel installation, first-time integration with BVMS, and the initial installation performed in conjunction with IndustrialENET. Thesystem also includes several industry-leading features, such as the ability to ignore normal vehicle traffic when monitoring for security and safety events. Using geospatial technology, it also boasts the ability to detect real-time vehicle speeds, which becomes increasingly more difficult as vehicles move farther away from the camera location.

"The system we deployed in the Tom Lantos tunnels not only provides video surveillance for the protection of the tunnels, but it also provides safety and operational information via real-time speed notifications and alarming on anomalies," said Kevin Campbell, vice president of sales at PureTech Systems. "The added benefits of integrating with BVMS and working with IndustrialENET make this installation that much more valuable for PureTech Systems and our customers."

The installation marks another milestone in the use of geospatial technology to solve problems that previously proved difficult with traditional video algorithms. In addition to tunnels, the technology is applicable to other transportation applications involving normally busy scenes, such as transit centers, roadways, airport queues and parking applications.
