Hi Bin, Rui,
very interesting paper indeed. As for what the use may be for ranking
streets according to some other criteria then administrative/functional
rankings designed by road network planners, we have been looking at how a
similar process may underline people's inference of familiarity with a
street. We argued that developping experiential rankings may support
generation of better route directions. See Tomko, Claramunt, Winter
(2008): Experiential hierarchies of streets , Computers, Environment and
Urban Systems 32(1): 41-52

and some consecutive papers. I am reading Bin's paper with great interest,
as he was able to look at actual correlation with traffic data. In our
approach, we had to use named streets as basic network elements, as common
labels are relied upon in route directions. I will see if the two
approaches could be brought together somehow.
cheers
Martin
