 ThermiCam has already proven to be an effective way to minimize traffic blocking on the Utrechtseweg, and to maximize the traffic flow for the different types of road users. www.its-ukreview.org 37 ThermiCam Thermal imaging sensor ThermiCam is an integrated thermal camera and detector for vehicle and bike presence detection and counting at signalized intersections. ThermiCam detects vehicles and bicycles at and nearby the stop bar. The intelligent ThermiCam sensor will transmit its detection information over contact closures or over IP to the traffic light controller and will thus allow a more dynamic control of traffic lights. The sensor picks up heat energy coming from the cyclists and motorists and uses this to make a distinction between the two. This way, green times can be adapted depending on the type of road user. ThermiCam will also detect cyclists and vehicles at night or when the sun is low, whether the road users are moving or stationary. The thermal sensor can also be used to count cyclists, even when they are riding in group. This functionality can work simultaneously with the presence detection functionality and uses the same detection zones and regions. ThermiCam is a very interesting alternative for detection loops. In the case of the Utrecht intersection, it was even impossible to use detection loops, because the intersection’s different roads connected on a bridge deck. In addition, today’s most common detection loop solutions cannot make an efficient distinction between cyclists and vehicles. Conventional, visible-light video cameras were also not a good solution, because detection from these products is often not reliable at night and during hours when the sun is low on the horizon.

Conventional, The ThermiCam installations at the intersection along the Utrechtseweg serve two purposes. First of all, they make sure that bicyclists receive sufficient green time for the traffic lights giving access to the bicycle lanes along the Utrechtseweg. Second, they make sure that bicyclists do not generate green time for motorists that want to cross the Utrechtseweg. This set-up has already proven to be an effective way to minimize traffic blocking on the Utrechtseweg, and to maximize the traffic flow for the different types of road users. “The ThermiCam bike and vehicle detection works perfectly, also in the darker hours and in cold weather conditions,” comments Guus Sluijsmans. “We are happy to have found an efficient detection solution for this difficult, mixed traffic situation and that we have been able to contribute to a smooth traffic flow at this intersection in the city of Utrecht.” visible-light video cameras were also not a good solution, because detection from these products is often not reliable at night and during hours when the sun is low on the horizon.
