Combine lanes for walking, biking, trams, moderate-speed vehicles, and below-grade trains with intermodal stations.
People need human-scaled pathways around their city that offer many different modes of travel including walk- ing and cycling, that are beautiful, ecological and functional, and that link with other modes of travel.
Therefore:
Within the 400 meter grid, lay out a greenway corridor system at a roughly 1600 meter (1 mile) spacing, forming rings around central parts of the city. Assure that they connect to key nodes of transpor- tation and intermodal travel.
Mobility corridors are focused on high-speed inter-ur- ban mobility for vehicles, but they leave out the lower-speed forms of travel for more routine urban trips. The pattern of the greenway corridor combines generous lanes for walking, biking, surface trams, moderate-speed surface vehicles, and below-grade trains, all linked by periodic intermodal stations. It is thus convenient to travel along a greenway corridor to intersect other train stations and transit lines within the region and beyond.
See Greenway Corridor Layout for routing considerations.
When the Polycentric Region will provide functional and beautiful pathways for transportation.
Then run the greenway corridors adjacent to Sanctuaries that provide housing and other uses.
