Abstract: US 95 traffic is split onto Jackson and Washington, main street retains on-street parking. Beautiful example of a mixed-use, pedestrian friendly area that also has great multi-modal access.
Abstract: As designed, the large outer circle is a two-way road, which could result in significant congestion. However if the outer circle were converted to just counter-clockwise, this would be a true TCI, and likely be extremely efficient. No plans for this, but it is a "Sustainable Design" because it can easily be converted to one-way operation.
Abstract: Calthorpe Associates was the architect for this TCI. It is in a brand new mixed use, high-end setting. The E-W street is not designed for high volumes, but it is nonetheless higher capacity than a similarly designed 2-way street. The N-S couplets are designed for higher volumes.
