Talk:Permeability (spatial and transport planning)

Semipermeable or nonpermeable urban form that supports transit
I can think of at least one semipermeable or nonpermeable urban form, at least for a satellite city or suburb, that supports transit, at least in park-and-ride form. This form resembles a snowflake or a feather or a starburst. At the center is a train or bus station, or perhaps a ferry dock, possibly attached to a parking lot. The streets all point to the hub, making the city permeable only at the hub, from which one also goes to other places, including the CBD of the central city. If we restrict car movement from the satellite city, transit ridership would presumably be high, especially if a lot of people work in the central city. Also, the satellite city would likely have a decent transit ridership itself, if it's big enough: the downtown area would naturally be clustered around the permeable point or "hub". Since the only way from point A to point B would be through the hub, if both points are not on the same street, the hub becomes the activity center and a frequent destination of people in general. &mdash; Rickyrab | Talk 14:10, 11 February 2011 (UTC)

This article lacks an explanation of the subject
The second paragraph already jumps to critique. — Preceding unsigned comment added by 2A10:8003:1BB1:0:B130:46A2:8202:ECE6 (talk) 22:33, 23 December 2020 (UTC)
