Hello Alain,

Could send it to me as well?

Ruben,

This one comparing SATURN (a traffic assign tool) and space syntax may
be useful:
http://www.spacesyntaxistanbul.itu.edu.tr/papers/longpapers/079%20-%20Barros%20Silva%20Holanda.pdf

You may ask Fred Holanda for more, he and his students have some work
in this area.

By coincidence, I found another paper wrote by Noah, Alain and Jorge
two days ago, about cycle routes:
http://repositories.cdlib.org/its/tsc/UCB-TSC-TR-2007-5/

I have used Space Syntax to evaluate cyclists routes while designing a
cycle route back in 2003 and that is something that where SS works.

My first paper about continuity lines has some bits about 'gate
counting' methods transportation engineers use:

Best Regards,
Lucas
