Many lines are based in New York City, where a Chinatown bus hub has been proposed. Philadelphia's Independence Transportation Center was built, in part, due to a 2007 Philadelphia Chinatown Development Corporation survey which concluded that many tourists arrived by bus and some Chinatown buses parked on the street (blocking traffic). Residents near bus stops in Philadelphia's Chinatown were more likely to complain about the buses. In Washington, D.C., bus-loading regulations were enacted in 2008 due to complaints about disruptive bus layovers. In Boston in 2004, the Massachusetts Bay Transportation Authority required Chinatown buses to have permits and stop at the South Station Bus Terminal. Although Fung Wah Bus Transportation was often ticketed for curbside parking offenses in Boston, it and Lucky Star Bus eventually headquartered at South Station because curbside-parking fines were exceeding the South Station terminal fees.
