Smart traffic light for ambulances

I want to create a project where I can control the traffic signal when an ambulance is approaching. for example, if an ambulance is approaching the traffic signal but the signal is red and vehicles are unable to move my project should allow the traffic signal to detect the ambulance and turn the signal green till the ambulance passes by and when it passes the signal should be back to normal. I want to detect the ambulance using rf transmitter and receiver. transmitter will be in the ambulance and receiver on the traffic signal. how can I implement this project using bolt?
