Indra brings Citilog on board for accident detection in the Silvertown Tunnel

Indra has chosen an automatic accident detection system from Citilog for the new Silvertown Tunnel in the UK, which is being built under the River Thames in London.

Citilog supplies video-based automatic accident detection solutions for tunnels, bridges and motorways. The company will integrate its automatic accident detection (AID) system to reduce congestion in and around the tunnel between the London Borough of Greenwich, the Peninsula and West Silvertown on the north bank of the River Thames.

The 1.4km long twin tunnel will have two lanes per tunnel, with dedicated lanes for heavy goods vehicles and buses. There will be no pedestrian or bicycle access, but a shuttle bus will be provided for cyclists.

The AID system, which includes 59 CCTV cameras, improves security and incident management through real-time incident detection and response, while also minimizing false alarms while maintaining high detection accuracy.

Thousands of video clips are used to train an advanced network that reduces false alarms and allows operators to focus on real emergencies. The AID system can also be easily updated and expanded.

“Our long-standing partnership with Indra was a key factor in providing the AID system for the Silvertown Tunnel,” said Volkert Samplonius, Citilog’s Vice President for the Ibero-America, Israel, South Africa, Australia and New Zealand region. “Our excellent detection rate, low false alarm rate and rapid response to incidents are a perfect fit with our commitment to safety and efficiency.”

Last autumn, Riverlinx CJV, a joint venture to which Transport for London (TfL) and Riverlinx SPV outsourced the design and construction work for the project, awarded Indra the contract to equip the tunnel with its In-Mova traffic platform and intelligent transport systems, including communications systems, radio communications network and traffic signals. Riverlinx CJV consists of Ferrovial Construction, BAM Nuttall and SK ecoplant.

The company’s technology is already used in the 12 London road tunnels managed by TfL and is also being implemented in the Hindhead Tunnel for England’s National Highways authority. The Hindhead Tunnel is part of the 6km dual carriageway that will replace one of the last remaining single-lane sections of the A3, which connects London to the southern port of Portsmouth.
