I'm wondering what transportation planners -- and planners, generally -- think of using vehicle capacity analysis as a determinant of neighborhood quality of life. It seems to me that the two are related -- the more traffic, the more noise/vibration/congestion and therefore a perception of decreased neighborhood quality -- but that the analysis lacks quantitative metrics. It's more art than science, I'm guessing, but that's where y'all come in.
Obviously, numerous factors would play into the equation: local traffic habits/police enforcement/urban design, and others. I'm thinking not of two lane roads in a rural area but rather of a fairly densely developed urban grid.
What sayeth the Trobbing BrianTM?
