Yes, this film is more "New York Centric" than I would usually cross post here, but I thought the simple illustration of the value of bus-only lanes was a good one and one we could use again.
The film tracks the growth of New York City, and the number of people taking the bus into the Big Apple from New Jersey over the decades but notes that the bus access to the Lincoln Tunnel and other crossings has remained static. As more and more people commute into the city from New Jersey; the Port Authority who controls the bridges and tunnels, New Jersey who controls the roads leading into crossings and New York are going to have to figure out more ways to get more people into the city. Sometimes the most obvious answers are the best ones. Just increase bus capacity and this particular congestion problem is solved.
Full disclosure: in addition to the obvious ties between LA Streetsblog and Streetfilms, this film's narrator was my boss when I worked at the Tri-State Transportation Campaign.
