Megaregion Freight Planning: A Synopsis (open access)

Megaregion Freight Planning: A Synopsis

"Megaregion interest has grown strongly in the last decade and is now seen be a growing number of planners as offering effective contributions to problems such as modal congestion, development disparity, and air pollution that individual metropolitan areas or cities cannot resolve individually. Megaregion planning presents an alternative way of mitigating metropolitan problems of large-scale transportation systems, green infrastructure, and economic development and has attracted a number of transportation advocates since 2000."
