[sustran] cost to a city of a single say 3 km. car trip during the day?

[eric.britton]

1.       What is the cost to a city - to your city? - of a single say 3 km.
car trip during the day?

a.       For the usual mix: including explicit to the city costs (I guess
that might be mainly road maintenance but there may be others that do not
come immediately to mind) -- and also of course  the environmental and other
external costs.

b.      I understand that most of the costs will be in the latter categories
- and I understand as well that these are not for the most part born by the
city (as an accounting unit).

c.       But still if I am a responsible 21st century mayor, I would want to
know that number because it would help me make a lot of good decisions. 

d.      It might be handy to see these in a bit of detail, but it is really
the bottom line number (and its explanation) that holds the key

2.       It would be great if you could lend a hand with this.

3.       And BTW, if I know this, then I can start to play with it in order
to think about how the city might take an active role in financing a city
bike project such as Vélib' or the one your mayor may be thinking about.

 

Your good help in this will be your own reward,

PS. Again, if the Greening of Paris series and the in-process Vélib' policy
brief interest you at all, this is to let you know that the latter is being
updated about twice a day and that you can find it on the left menu at
http://www.invent.newmobility.org. As indicated earlier, comments, etc. are
warmly welcome. It looks as if we will have this fully in the bag by the end
of the week, but it already is a pretty good read (I am told).
