My favorite graphics in "Transportation and the Shape of Cities" #9: Three distinct schools of thought — classical, landscape, and modernist—have shaped pedestrian urban design in the age of the car. All have different ideas about land use, separation from traffic, safety, and visual interest.

My favorite graphics in "Transportation and the Shape of Cities" #8: A bike lane can be built with paint and plastic, made more durable with curbs and planters, or built into the infrastructure of a rebuilt street. All take the same space, but the cost and the feel of the street are quite different.

My favorite graphics in "Transportation and the Shape of Cities" #6: A typical transit route gets its ridership from lots of shorter trips that overlap each other, not from end-to-end trips. The more destinations along the way, the more of those trips it can serve, and the higher ridership is.

My favorite graphics in "Transportation and the Shape of Cities" #5: The structure of US transportation funding and decision making is complicated (example: Houston.) That shapes what we build and what we don't, and it makes it harder for the public to figure out how to change things.

Some of you may point out that your local commuter rail line is not through running but should be, but is it as comically not through running as one? (Ormskirk, UK, where electric Merseyrail trains meet diesel Northern services.)

Approaching Saltaire, North Yorkshire. The rows of matching houses, stores, public buildings, and mill are the "model village" built in the 1850s by mill owner Sir Titus Salt so his workers (unlike most of their peers elsewhere) would have clean housing, educational opportunities, and recreation.
