Hello. I am currently a mechanical engineering major. I am drawn to the mechanical engineering major because I like physics, all science really, and I believe this degree will teach me a lot about how devices/machines/physical objects work as well as how to build/manipulate the world around me. And good career options. I recently became interested in the idea of being a traffic engineer, because I love the idea of designing roads/transportation infrastructure. It seems to have the fun design work of an architect with the cool computational work of an engineer, while throwing in some general concepts of psychology, even a touch of biology, both of which I am fond of. I am interested in tidbits of every area of science, and am kind of a "big picture" concepts person, so working with traffic systems seems cool to me. I am prepared to handle detailed work as well of course, I am just saying that I like to look at situations as a whole. With a mechanical engineering degree, can I get involved in civil engineering departments or firms? Civil engineering seems to be the path to traffic engineering. Btw, only structural engineering is offered at my school, not civil.
