Smoothing intersection flow in the Netherlands

6778 Flir's ThermiCam thermal sensors have been installed at a major signalised intersection with the Utrechtseweg (N237) and Wilhelminalaan in Utrecht in the Netherlands In a bid to smooth traffic flows while also taking account of the presence of cyclists.  

ThermiCam is an integrated thermal camera and detector for vehicle and cycle presence detection and counting at signalised intersections and provides an alternative to in-road loops. The sensor detects heat energy generated by cyclists and motorists and uses this to make a distinction between the two and transmits the information over contact closures or IP to the traffic signal controller to allow green times to be dynamically controlled based on the type of road user.

ThermiCam detects cyclists and vehicles in all light conditions, regardless of whether traffic is moving or stationary.  The sensor can also be used to count cyclists, even when they are riding in group.

“For this specific project, we needed a solution that was able to efficiently detect bicyclists and neglect motorists at the same time,” says Guus Sluijsmans, traffic engineer and account manager sales at 6999 Imtech Traffic & Infra, which installed the sensors. “The ThermiCam sensor from Flir Systems is the only solution I know that can efficiently make a distinction between bicyclists and motorists on the same traffic lane.”

    With the Idris system now validated as a speed verification tool, the way is open for loops to be used in more complex enforcement applications. Diamond Consulting Services (DCS), developer of the Idris inductive loop-based vehicle detection and classification system, has recently successfully conducted validation trials which, the company says, open the way for Idris to be used for speed verification and loop-based sensors to be used for more complex applications such as speed-on-green and differential spe

    Elmar Brockfeld, Alexander Sohr and Peter Wagner from the German Aerospace Center's Institute of Transport Systems look at the prospects for floating vehicle data systems. Although Floating Vehicle Data (FVD) or probe vehicle fleets have been around for about a decade, the idea behind them is of course much older: from probe vehicles that flow with the traffic it should be possible to get a precise, fast and spatially near-complete picture of the prevailing traffic flow conditions in an area under surveilla
