Question Given a public transportation concept, provide one to three examples of models to include schematic, mathematical, and physical. What type of data would need to be collected? What types of decisions would be informed by these models? (Professors Note: We're much more interested here in the systems engineering aspects of the models than in public transportation. So, you should discuss the various factors of each model, in other words, the type of model, how would this model be used in the development of a public transportation system, where in the development life cycle of the public transportation system would the model be used, what data would be needed for the model, what decisions will this model help you make and so forth. I don't see the need for sketches, if a sketch is one model you want to discuss, then just talk about the aspects of that sketch.)
