routes for cyclists. The Southwest Corridor also provides cycling infrastructure, as does the East Boston Greenway. Many MBTA riders use a bicycle to get to a nearby station, and the number of bicycle racks and lockers has been increased. However Bicycling magazine, in its March 2006 issue, named the city as one of its three worst cities in the United States for cycling. The distinction was earned for "lousy roads, scarce and unconnected bike lanes and bike-friendly gestures from City Hall that go nowhere—such as hiring a bike coordinator in 2001, only to cut the position two years later". Neighboring Cambridge earned an honorable mention as one of the best cities for cycling with a population of 75,000-200,000. Since September 2007, when Mayor Thomas Menino started a bicycle program called Boston Bikes with a goal of improving bicycling conditions by adding bike lanes and racks and offering bikeshare programs, the city has improved accommodations for bicyclists in a number of ways. The least visible improvement is zoning and building code changes to encourage showering and locker facilities in major office buildings. Better signage and lane markings for bicyclists are starting to appear. More visible enforcement of traffic regulations on motorists, bicyclists, and pedestrians has commenced. Boston has an active Critical Mass ride group, and MassBike is a bike advocacy group active in supporting cyclists in the area. The LivableStreets Alliance, headquartered in Cambridge, is an advocacy group for bicyclists, pedestrians, and walkable neighborhoods. Maps and guides The Boston regional Metropolitan Area Planning Council (MAPC) publishes a large and detailed "Greater Boston Cycling & Walking Map", which it distributes free of charge. The map is also available online and in downloadable form, and revisions are solicited from the general public. In addition, a small private company called Rubel BikeMaps has for many years published and distributed an extensive lineup of books and maps covering Boston, the state of Massachusetts, and nearby areas of New England. These publications are for sale at many bicycle shops, and online. Because of recent expansion of bike lanes and other facilities, plus increased input from the public, it is important to use the most recent editions of these maps and guides. Rubel BikeMaps also publishes Car-Free in Boston:a Guide for Locals and Visitors, still in its 10th edition . Prepared by the Association for Public Transportation (APT), this book contains extensive information useful to bicyclists and
