Silo X: Single Project vs. Complete System

There's been a lot of talk over this study today. It comes at a perfect time for journalists to skim the abstract and form their own conclusions before actually digging in to the details. What the study does though is look into the life cycle costs of different transportation modes. As Jebediah states in his post:
What’s totally missing in their “complete” estimates for these various transportation modes are the virtuous effects of rail: creating denser communities where people tend to walk more, own fewer cars, live in smaller abodes, and spend less time stuck in traffic jams.
Where could we get such a look into that community? Why Portland of course where they began preliminary calculations of these things in a basic way for transportation and building emissions.

This can and has been replicated (pdf pg 53) in other places such as Over the Rhine in Cincinnati. Hopefully other places will look holistically at the benefits of the whole package instead of just these news hopping studies that continue silo thinking. It is certainly good to look over the life of projects, but as mentioned, it's only the life cycle of that individual transportation project and nothing else related.
