As for monitoring heterogenous traffic, thermal imaging can be a precious camera type reducing overall system costs and increasing reliability.
On contrary to Visible and NIR-based detectors, LWIR cameras are not affected by the lighting conditions of the scene: e.i. night vs day, and sun orientation.
This remains true over long distances, enabling the detection of a child, a biker, a car or a truck.
Once coupled with relevant processing, LWIR cameras turn to be a key asset of ITS, reducing the number of cameras while increasing alarms reliability. This helps the manager on duty to take quickly the right decision in case of e.g. obstacle detection, reverse direction vehicle, abnormal traffic jam… to ensure road-users security as well as optimal commuting time.
