A Traffic Signal Preemption Transmitter alters a traffic signal’s phase time by interrupting normal traffic signal timing to provide a green light to approaching emergency vehicles. We see rapid growth in populated areas as a challenge that is currently the primary key issue in the U.S.

TSP systems are framed in a way that they give emergency response vehicles the green light when they approach a signalized intersection while providing a red light to conflicting approaches.

In crowded areas, emergency vehicles may undergo queues due to which they have to slow down, adding more time to reach the scene of an incident. However, a green light moves the queue as the traffic is spread before the emergency vehicle’s arrival. In such cases, EVs maintain a bit higher average speeds than expected due to the typical traffic situations.
