I had the opportunity to attend a “Travel Time Reliability” workshop at Metro a few weeks ago (I never said I wasn’t a wonk). The speaker was kind enough to forward the PowerPoint since I wanted to blog about a few of the slides.
My point here is that when most people think about congestion, they think in terms of capacity constraints. But the reality is that the pain has to do more with unreliability. Not that the two aren’t related – more capacity does make you less sensitive to SOME of the factors that create reliability problems, but it’s an expensive answer and there may be more cost effective approaches (with way fewer negative environmental effects than adding capacity).
More after the break.
