Welcome bikes. (“In Amsterdam, a city of 783,000, about 400,000 people are out riding their bikes on any given day.”) This step is only minimally about walkability, except for the point that bike traffic slows car traffic. It’s all about making cities more hospitable to cycling, which many U.S. cities are now doing. Although the drivers complain, both the research and my personal experience as a driver suggest that car traffic isn’t really inconvenienced much if at all when the addition of cycling infrastructure is thoughtful. Jeff does discuss the very interesting point that some experienced cyclists actually prefer riding in the main roadway rather than in a designated lane. Personally, if I’m on a busy downtown street, I’d rather have a dedicated lane; otherwise, I’d probably prefer to have full access to the road.
