"on a weekday, the average car driven into Manhattan south of 60th Street causes a total of 3.26 hours of delays to everybody else. (At weekends, the equivalent number is just over 2 hours.) No one car is likely to suffer excess delays of more than a few seconds, of course, but if you add up all those seconds for the thousands of affected cars and trucks, it comes to a significant amount of time."
I had to add to this thread because I found this quote in what appears to be a good analysis of Manhattan's transportation externalities and a proposal that includes congestion pricing.
If this is accurate, does it change your opinion on the need for congestion pricing? How much?
Would congestion pricing significantly reduce amount of traffic? I quite doubt it. People are willing to stay extremely long in the traffic, a few extra dollars of congestion charge on top of that won't make much of a difference, and cost of operating the scheme would be enormous.
Unless the congestion charge is really extremely high, like $100 a day, that would probably work well enough to reduce traffic, but it's unlikely they'll ever do that.
Yesterday I heard an interesting story on the radio about US President Obama's pick to head the Office of Information and Regulatory Affairs, Cass Sunstein. I recommend checking out the story, but here are a few key excerpts.
At the risk of starting a discussion that will be wrecked by political wrestling, I'm always hopeful when I hear about governments applying what we learn from science to policy. Not to say that this always generates good policies, but it does generate the best policies we have reason to believe will be good (so long as you ignore the issue of actual politices that might get in the way).
