Moving walkways AUG 10 2009
At the beginning of the 20th century, the idea of moving walkways was in vogue. After successes in Paris and Chicago, plans were drawn up for a three-speed moving sidewalk across the Brooklyn Bridge to alleviate traffic on the crowded bridge.
With the Brooklyn Bridge walkway, Schmidt upped the ante. This time he envisaged a loop system at each end of the bridge, with a series of four ever-faster walkways. Passengers moved from one to another until finally taking a seat on the benches aboard the fastest, which whisked them across the bridge at 16 km/h [~10 mph]. Because the system ran constantly, there would be no waiting and little momentum lost on stops and starts.
