Think about the Object-oriented Design Methodology and how it will apply to a project that models traffic. What objects would you use. What would methods do with those objects. Produce a document that shows that you spent some time thinking about this. List objects, methods, what objects would contain, what methods would do, etc. Include names of classes and methods, etc. It doesn't have to be complete. But, the more detail the better. Language is Java (no code needed just the document with objects methods names etc)
