Hi Ian, The paragraph reminds me of Todd Litman or something about traffic calming. I would suggest you to search Todd Litmans site (www.vtpi.org) or even our module on Mobility Management written by TL (www.sutp.org) and also the book by Newman and Kenworthy "Sustainability and Cities". cheers sunny Ian Fiddies wrote: > Hi All > I wonder if anyone can help me.
