Bing Maps added "transit routing" to its directions options. There're more than 10.7 billion public transit passengers per year in the US alone. In this initial release, Bing Maps will cover 11 cities: Boston, Chicago, Los Angeles, Minneapolis, New Jersey, New York City, Philadelphia, San Francisco, Seattle, Washington DC, and Vancouver. You'll notice in the screenshot that the transit information is featured alongside each route option. This helps users easily compare route options based on their existing knowledge of transit and their preferences. Transit options are available for bus, subway, light rail, and local rail.
Also improved business details and information about landmarks. Open up movie house detail pages and you'll see movie listings added to "nearby" panel.
