Assalamua'laikum and very good morning.
Today i'm having a site task where we need to make a survey based on parking in my campus. We need to count every single vehicle in and out of the park. Where class 1 is represented by motorcycle, meanwhile, class 2 goes to cars, class 3 represented by vans and small lorries. On the other hand, class 4 is filled with buses and big lorries. So, let me countinue my work. Well, this is a part of civil engineering works. Thanks for reading.
