BRT Comes Out Ahead of Light Rail, Again
The World Resources Institute (WRI) recently presented a report comparing BRT and LRT in the “medium investment” range for the Maryland Transit Administration (MTA) on the Purple Line, which would connect suburbs around Washington DC with the city center. WRI’s analysis confirms that BRT is the option that would work locally to fight global warming, with a medium-investment system cutting carbon dioxide emissions by almost 9,000 metric tons per year, equivalent to taking about 1,600 cars off the road (PDF).
In an interview with Worldchanging, the report's authors, Dario Hidalgo and Greg Fuhs, address the CO2 numbers: "While this could change in the future with a major and permanent shift to low-carbon energy sources, for the foreseeable future we would likely continue to see higher CO2 emissions from light rail in this case," said Fuhs.
The report finds that BRT would
be more cost-effective and lower-risk, particularly with the current economic situation. With tight state and federal transit budgets, and the recent hullabaloo over the stimulus package, it will be difficult to get substantially more funding for transit.
In San Francisco, Central Subway aside, policy makers appear unwilling to build more fixed-rail systems in the near term, preferring instead to go with BRT. The SFCTA and MTA are moving forward with the Van Ness and Geary BRT lines, which still need to clear environmental analysis, but could be online by the MTA's Centennial in 2012.
"Other cities are building light rail very cheaply and operating it well," said Livable City's Tom Radulovich. "The big problem with San Francisco is that we build incredibly expensive light rail, like the Townsend 3rd, and we run rail like a bus. We're not being smart about our investments."
All right Choo Choo Heads and BRT-ophiles, we know you're reading, tell us what the future of San Francisco's surface transit should look like.
