I understand that not much of it is older than 1906, when the fire and earthquake destroyed much of the city.<BR/><BR/>It's possible to change streets, however old they are.

Many of the older neighborhoods are quite narrow with on street parking on both sides of the street. There would be no place to put this kind of system, unless the parking was taken out (SF currently only has 2/3 of the needed spaces to accommodate the number of people who drive into the city, so no one is going to go Adriennehttps://www.blogger.com/profile/10828679738494471220noreply@blogger.comtag:blogger.com,1999:blog-3102538965694240940.post-40114836518816491612008-11-11T07:30:00.000+01:002008-11-11T07:30:00.000+01:00Adrienne, how old is the place you're thinking of ...Adrienne, how old is the place you're thinking of ? Assen has existed for 750 years.

I can see the bike friendly light system, but I don't know how roads like that could be built here.

Stopping a bicycle over the three dots will signal the traffic light to change.<BR/><BR/>As far as I know, only Toronto uses the three white dots method.

There is another set a few metres behind the camera to catch bikes as they approach.<BR/><BR/>Because these are passed only by bicycles, they are very reliable for bikes.
