## Traffic Problem
// Spawn 4 streets
// Spawn 1 dispatcher
// Shared variables: right_of_way, car_queue[]

## Dispatcher
right_of_way = 1;
while(1){
  sleep(random); // Wait random time
  for(i=0;i<random;i++){ // Spawn random # of cars
    car_queue[random]++; // Add car to random street queue
  }
}

## Street
while(1)
  if(right_of_way){
    if(car_queue[me]){
      car_queue[me]--; // Remove the car
      sleep(2); // Do the driving
    }
    right_of_way++; // Right-of-way to next street
  }
}
