US Gets a Lesson from Develping Countries on Buses

The lowly bus is getting a makeover that could one day help U.S. workers whiz past traffic to their jobs on time while saving fuel in the country that is the world’s largest oil consumer. For decades, most U.S. commuters have maligned buses as noisy, dirty and much slower than cars in city traffic, since they make many stops. But about 120 cities in developing economies from Colombia to China that have invested in high-technology systems known as bus rapid transit, or B.R.T., have taken the transport mode to a higher level.
