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.”

    David Crawford investigates innovative congestion management in Florida. The largest US city by area is well into the implementation of an ambitious congestion management system (CMS) on the scale of those of higher-profile centres such as Seattle and San Francisco. Regional agency the North Florida Transportation Planning Organisation (NFTPO) aims to ensure that commuters on major highways in Jacksonville can rely on a minimum 72km/h (45mph) driving speed in normal conditions.

    Jenoptik’s Uwe Urban looks at the advantages of ‘sensor fusion’ for the ITS sector. When considering the ideal sensing and monitoring system to enable the ITS sector to deliver improvements in mobility and road safety, for general policing security and border protection, we have to think beyond radar-base systems or laser scanners. What is needed today are solutions for detecting and tracking vehicles while recording evidence to deacide if any action is necessary. There is no sole sensor capable of

    Sick’s new hot spot detector system proved its worth only one week after being installed by preventing a fire in the Karawanks Tunnel, Austria. A semi-trailer truck with a wheel temperature exceeding 200 degrees centigrade triggered the alarm as it passed the hot spot detector. Closer inspection indicated that in addition to the overheated brake, the vehicle was also travelling with two cracked brake discs. Developed by Sick’s Swiss subsidiary ECTN and based on the Sick LMS511 laser sensor with the T

    Road authorities have a lot to gain from high-resolution traffic data, argues Pravin Varaiya. Traffic engineers have traditionally been forced to operate with limited data regarding the performance of their arterials. Traffic studies are often commissioned once every three years, over a few days, to get an updated estimate of utilization.
