Boston Transportation Data

Sometimes, people ask for transportation data that they assume doesn't exist but, au contraire, it does. There are some other data I have which I can provide on request, but aren't posted publicly (and some of those are based on calculations I've made which might not be entirely perfect). Here are some of the resources I know of. Most are large PDFs, because that's where data exists, right?

• Massachusetts traffic volume counts. This has most vehicular traffic counts in the Commonwealth.
• MBTA Blue Book has a lot of detailed information on MBTA operations. It does not have everything, but a lot: bus and transit ridership, some historic data (older versions of the Blue Book have data going back further; at some point I would like to compile these older data in to one document beyond Commuter Rail, which I have).
• Commuter Rail counts by train. These data are outdated (2012) but give a good idea of how many people rider specific trains, at least on the day the count was completed.
• Commuter Rail system survey. These data are even more outdated (2008) but even richer, including access and transfer data. It's pretty dense.
• Changes to MBTA service since 1964. A very comprehensive look at every bus line in the system, and every change to service in the past 50 years. 
• Summary of Commuter Rail operations, including the number of train sets required.
• MBTA salaries, in a very not-useful PDF document. I have an Excel somewhere. 
• Keolis bid document, with salary information for various positions and job descriptions.
• NTD Database, with transit system comparisons. You can also download the whole database as a database or in excel.
• Monthly data by mode, 2007-2014
• Archive of Commuter Rail schedules (Dave Weebly).

I will update this post frequently as needed.
