Free traffic arduino

the project idea is about traffic lights with sensors, the purpose of this project is basically when there isn't much traffic there is no use of people in cars waiting, and it's the same for pedestrians, when someone wants to cross the street when there isn't any car he/she shouldn't wait. what I need is for you to write an arduino code that includes the following function on top of the reqular traffic light functions: 1- to be able to detect any vehicles 2- to count the number of vehicles that pass the traffic light 3- to be able to detect the emergency sounds such as the ambulance requirements: 1- Aurdino board 2- light sensor 3- ultrasonic sensor 4- detecting light night switch finally, write a report describing the functions of the code ( attached is a picture of Aurdino board available to me )
