This document discusses the need for sustainable transportation networks. It argues that current transportation networks concentrate all traffic on major roads and fail to support other modes of transportation like walking and transit. To achieve key goals like compact development, multimodal access, and reduced vehicle miles traveled, the document advocates implementing a finer-grained network of complete streets to disperse traffic and encourage sustainable modes of transportation. It presents examples from Charlottesville, Virginia to illustrate how robust multimodal networks can transition areas from suburban to more urban forms of development.
