Henry Barnes (traffic engineer) : ウィキペディア英語版 | Henry Barnes (traffic engineer)
Henry A. Barnes (December 16, 1906 – September 1968)〔(HENRY BARNES (1906-1968), Social Security Death Index )〕 was an American traffic engineer and commissioner who served in many cities, including Flint, Michigan; Denver, Colorado; Baltimore, Maryland; and New York City. Barnes was responsible for many innovations in applied traffic engineering, including the Green Wave of coordinated traffic signals, the application of actuated traffic signals (signals set off by the presence of an automobile or a pedestrian pushing a button), and the introduction of bus lanes. ==Barnes Dance== The Barnes Dance is a street-crossing system that stops all traffic and allows pedestrians to cross intersections in every direction at the same time. This system was first used in Kansas City and Vancouver in the late 1940s. Subsequently it was adopted in other cities such as Denver, Colorado, New York, San Diego, Baltimore, Maryland, and Washington, D.C.. Barnes stated that he did not invent the concept but promoted its widespread use. The phrase originated from City Hall reporter, John Buchanan, who wrote, "Barnes has made people so happy, they're dancing in the street."
