Repeat - Public Transit Utilization

Just because it seems useful to the current debate, a repeat blog-post from last June I think. Here is:

Public Transit Utilization in Allegheny County - 2000

Also, Mark once took this and overlaid a map with population density to see where there are concentrations not using transit. I think the intention was to identify where there could be new markets for service, of course we seem to be going in the other direction.

For those who are interested, I have thrown together a short bibliography on transportation policy issues in Pittsburgh. You can view it here. It is by no means whatsoever comprehensive, it is just a compilation of some things I have scanned, have used or know of for the most part. I know this is something ideal for the Wiki idea that Mark and Jim started. I have to admit that if I knew how to actually do something with that I would try, but for the moment this is just a quick and dirty data dump I will expand as I have time.

and there is still good discussion going on in the earlier post: Bus Economics....

Holy cow - I just read that 1935 comment piece in the bibliography you posted. Did anyone ever produce any comparative analysis of the efficiency of streetcars in 1935 vs. buses in 1985, just to see if the predictions the trolley folks were making held water?

Also: do you have a bigger version of the map you've posted?

I am sure there isnt any such study.. it would fall in the realm of historical analysis if anything. The history of trolleys and their demise is its own little tempest anyway.

see if this works:

Here's a repeat of the comment and my link:

Pardon my ham-handed attempt, but I tried mashing density and ridership maps together. You can find the results here.

You can see where the brown stains show through that a CT is high density but low ridership. If the map is anything to go by, areas like Shaler and Ross have high density and low ridership.

----

Apologies to Chris and Jim. I haven't been keeping up with the wiki myself. Will look into it and get back to you. I'm sure that ridership-wise we look pretty pitiful compared to 1935. If it's any consolation, we sure do enjoy driving all the cars we've bought since then.
