For a career in traffic engineering you need mathematical skills in algebra, logic, and geometry and a good working knowledge of statistics. You should have language skills that will enable you to write extensive reports that contain statistical data. You must be able to present such reports before groups of people. You should also be familiar with computers and electronics in general. You need a basic understanding of the workings of government since you must frequently address regulations and zoning laws and meet and work with government officials. A high school diploma is the minimum educational requirement for traffic technicians.
