Description: in this project, you will implement an intelligent traffic light system where cars anive at a "one-way only" tunnel. Your program should enforce the requirement that "only at most N cars in one direction can go through the tunnel at a time". The goal of the project is to leam multi-threading with bcks and condition variables. For implementation, you need to have variables for traffic lights on both North and South directions. Lights can be RED or GREEN only. If the light turns RED, m car should attempt to enter the tunnel. Otherwise, N cars should be allowed to enter and leave the tunnel You may either have one thread per car, in this case, N threads need to be woken up when the light turns GREEN. Or you may have one thread per direction and then manage to make N cars leave the tunnel in a sequence. Cars should arrive at a random time with an average interval of 60 seconds. To achieve this, you may do random-120, where the random number is within (0,1). Or you can do rand(%121. It should serve the same purpose. Please take account of the time for cars to leave the turnel, e.g., 60 seconds, as well as the time for a car to start and follow another car, e.g., 5 seconds. Such time can be implemented through a sleep function. Your program should calculate the total time taken for M cars in both directions together to pass the tunnel Your program should display the following events on screen: Thread creation When light changes for one directions Periodic print out of time taken so far There are two parameters to pass from the command line: Mand N Testing: Your program should run for Mcars until all cars pass the intersection. . . 1/2 30/12/2020 Project Cygwin compilation: "g++ -std=c++11 sample.cpp - pthread" Project Report: a max of 2-page brief description of the results (total time) on different combination of (M, N). You should briefly justify the result based on your observation and analysis.
