WASHINGTON — It’s the fastest, cheapest, most effective way to move large numbers of people in an urban area, some transit advocates have come to conclude.
But it’s not a streetcar or light-rail system: It’s a fleet of buses that acts like one.
Bus rapid transit is common in Latin America and Asia, but it hasn’t caught on as quickly in the United States. Most transit investment in the U.S. over the past few decades has concentrated on subways, light rail and streetcars.
According to its boosters, bus rapid transit can spur just as much or more economic development generally at a fraction of the cost, although more sophisticated projects can be just as expensive as rail. Real estate developers and city planners tend to prefer rail systems because of their durability and capacity to move large numbers of people.
