No, he's not according to the violations cited in Final Order, page 6, section heading #14; in particular:
By reviewing, critiquing, and altering an engineered ITE formula, and submitting the critique and calculations [...] to members of the public for consideration and modification of Beaverton, Oregon's and worldwide traffic signals, which signals are public equipment, processes and works, Jarlstrom applied special knowledge of the mathematical, physical and engineering sciences to such creative work as investigation, evaluation, and design in connection with public equipment, processes, and works. Jarlstrom thereby engaged in the practice of engineering under ORS 672.005(1)(b).
...and summarizing: By engaging the practice of engineering [...] without registration, Jarlstrom violated [laws]. [...] By again providing the public with his traffic engineering calculations for the modification of Beaverton's traffic signal timing, Jarlstrom again engaged in the practice of engineering and, specifically, the practice of traffic engineering. He thereby violated [laws] on a third occasion. By providing his publicly released traffic engineering calculations to the sheriff of the 20 county where he advised changes in traffic signals, Jarlstrom again purported to be authorized to engage in, and did engage in, the practice of engineering. He, therefore, violated [laws] on third and fourth occasions.
