TfL trials Qvision technology

Transport for London (TfL) is trialling Qvision Technology’s animated jam cams technology at the Blackwall Tunnel.

The American company’s solution shows short video loops of traffic conditions as opposed to the standard jpegs found on most traffic information websites. However, the company says its solution is ingenious because it delivers all the value of live streaming at a fraction of the cost and technical complexity.

The trial is focusing on the key Blackwall Tunnel route in London. Four cameras, two north and two south of the tunnel, monitor the carriageway and key side roads, including the route to the O2 Arena, with a total of 14 views.

Users are being encouraged to give feedback on the usefulness of moving images by completing a short survey.

Alan Bristow, TfL’s traffic manager and director of road space management, said: “We’re always looking for new ways to make information more accessible, to ease journeys and reduce congestion. If there’s disruption on our roads, we want to make sure people find out about it before they get stuck in it. These animated jam cams will help travellers make a better judgment about how much traffic there is on the roads, and plan accordingly.”

Greg Yova, founder of Qvision, added: “This is our first project outside North America and I want to thank Transport for London for their support and also their commitment to improved traveller information, which helps them do their job better and make Londoners’ journeys less stressful. I am sure that our video solution, which shows speed as well as volume of traffic, gives a better idea of conditions while costing a fraction of live streaming.”
