Traffic Signal Preemption Transmitter?
An Introduction
“Traffic signal preemption transmitter” is a device that helps in the 
traffic signal’s phase time or sequence that can be changed or 
modified. Ideally, Preemption systems can efficiently decrease 
response times for vehicles in emergencies. Many studies suggest a 20 
to 55% reduction in response times and a 70% reduction in emergency 
vehicle crashes. These changes have significantly affected the results of 
medical emergencies, and there has been considerably improved 
traffic safety. 
How does it can help you?
Preemption systems are made in a way that they can help emergency 
vehicles to reach where they need to go with minimal intervention by 
automatically changing traffic light signals to let them pass through. 
But unfortunately, many of the preemption systems being used have 
outdated technologies that slow down the response times and even 
endanger the life of other drivers.
Improving Preemption with New Technology
Cellular and radio technologies are becoming very popular to 
overcome the shortcomings of optical and infrared solutions. When 
they merge with GPS, emergency vehicles can work out their entire 
route right away after receiving a call, and they can change traffic lights 
well in advance to clear out obstructions and make sure the vehicle’s 
safe movement to their destination.
Remote Monitoring & Reporting
New Preemption systems include dead-reckoning-enabled cellular and 
radio technologies and special features that cannot be found in 
competing preemption systems. Some preemption systems also 
include built-in cabinet monitoring to ensure they’re functioning 
normally and will be aware of the right people when something isn’t 
working.
Conclusion
Since the optical and infrared technologies developed, the traffic signal 
Preemption systems have come long way decades ago. The newest 
preemption systems, like GPS, cellular, and radio technologies, can 
help clear traffic well beforehand and dramatically lessen emergency 
response times. For Transit Signal Preemption (TSP) Transmitters or
