What is so expensive? The device used where I live simply has a sensor that will change the lights based on an infrared code signaled to it by an emergency vehicle. Like a fancy remote control.

That means the light system where you live has that built in from the beginning.
If it wasn't built in or the town has a fully networked Traffic Management System (which most cities do) you have to get the integration from the company that provides your traffic lights or something compatible with them OR get a whole new system.
