The first real problem with Killed by a Traffic Engineer is that the title is inaccurate--traffic engineers don't design roads. Literally, they engineer the TRAFFIC, how (mainly vehicles) move on roads. Think signal timing, queue lengths, merging and diverging, and interpretation of traffic control devices like signs. So yes, traffic engineers influence the design of roads, but they usually don't have the final say. They are a subject matter expert under a design manager.
