FLIR systems allows smooth intersection traffic flow 36 ITS REVIEW Annual Review 2015 The province of Utrecht was looking for an efficient way to let the traffic at the intersection with the Utrechtseweg (N237) and Wilhelminalaan flow in a much smoother way. More specifically, the traffic authorities needed to find a solution to allow the traffic coming from the Wilhelminalaan and from the exit of the KNMI site (Royal Netherlands Meteorological Institute) to have sufficient green time to cross the Utrechtseweg based on presence information of vehicles. In order not to create any unnecessary waiting time at the intersection, the presence of cyclists should not generate green time. At that intersection, bicyclists can only turn left or right before the intersection area, not straight ahead. For this specific situation, a separate regulation for bicyclists and motorists was the best suitable solution. Integrator and installation company Imtech Traffic & Infra selected the ThermiCam thermal sensor from FLIR Systems to do the job. “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 Imtech Traffic & Infra. “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.” Kristof Maddelein, FLIR Systems ThermiCam thermal sensors from FLIR Systems have been deployed at a big signalized intersection leading from Utrecht to Amersfoort, the Netherlands. Based on heat energy coming from bicyclists and motorists, the cameras from FLIR can detect both types of road users and make a distinction between the two. The cameras pass down their detection information to the traffic lights and this way, a separate regulation for bicyclists and motorists is made possible, all the while both road users are sharing the same road space. The result of this installation is a smoother and more logical traffic flow at the intersection. in Utrecht, the Netherlands
