Special crosswalks in Chinatown

Car traffic is given red lights and must stop all ways. Then pedestrians are given green lights and can walk four ways and diagonally. Then cars are allowed to proceed alternately. This is to prevent the wholesale slaughter of pedestrians. There are some of these 4 way cross walks in San Francisco Chinatown as well. They probably have these in Chinatowns all over the country. A study done in 2002 said that Chinatown has the highest concentration of motor vehicle accidents in Oakland.
