And look, Mark, you do have hills - coming from the underpass back to the street level. Mark, since you produce nice videos, it would be great to see one from a hilly portion of your country...if there is one ;-) If you decide to come to Canada, I can give you a free study tourMicheal Bluenoreply@blogger.comtag:blogger.com,1999:blog-3102538965694240940.post-78763069543477812722011-05-27T10:05:31.042+02:002011-05-27T10:05:31.042+02:00@Christhebull; exactly right.

This solution is only suitable for major junctions with a high volume of traffic and not in city centers.<br />That is what I meant with my last sentence. Both the examples I show in the videos are in (former) circular roads. Social safety in tunnels is always very important.

It is a good system although in the past it has been difficult to navigate these routes.

I believe there is one in rotherham, when I last used it the underpasses were sprawled with graffiti and covered in broken glass which seems to be common with underpasses in Britain meaning they are rarely built nowadays. A cycle underpass in my home town was filled in and replaced with a signalised crossing due to 'social' problems with it.leehttps://www.blogger.com/profile/05100364489299164604noreply@blogger.comtag:blogger.com,1999:blog-3102538965694240940.post-37389688290529806332011-05-26T09:06:49.255+02:002011-05-26T09:06:49.255+02:00Very interesting.

I simply don't see how one goes from what we have now in Los Angeles to that. The changes required are breathtaking: political will, rewritten standards, funding, etc. Making such changes would really require "loosing excitement" onto the streets, and in ways that I can't quite imagine now.
