Glad you are looking at this.  I like the idea of adding light rail.  In the new start locations this is commonly known by the public  as light rail.  I do think it fits better with streetcar and trolley.  Since the question refers to last week it is almost certainly travel in their home town (unless they were out of town for the majority of the week) so one could set up logic checks to test the reasonableness of the responses. 

 

I wish they would also shift to asking about the mode on the most recent day they commuted to work.  Transit is more commonly an occasional mode (compared to auto) and hence it is not uncommon for folks to use it a few time per week but not the majority and very common for folks to have it as a normal mode but not exclusive mode leading to some overstating of transit commuting use.  NHTS confirms a significant difference between actual and usual mode for transit.  Would be nice to shift to actual travel day mode.

Subject: [CTPP] American Commuter Survey (ACS): The Means of Transportation Question

 

Hello,

 

As you may know, the Census Bureau's "means of transportation" question on the current American Community Survey questionnaire (as well as the previous Census 2000 "long form") is as follows:

 

How did this person usually get to work LAST WEEK?  If this person usually used more than one method of transportation during the trip, mark (X) the box of the one used for most of the distance.

__ Car, truck, or van

__ Bus or trolley bus

__ Streetcar or trolley car

__ Subway or elevated

__ Railroad

__ Ferryboat

__ Taxicab

__ Motorcycle

__ Bicycle

__ Walked

__ Worked at home

__ Other method

 

Here at U.S. DOT, we (meaning FTA, FHWA, and BTS) are discussing whether updated descriptions might make more sense for the three public transportation categories associated with use of rail:

__ Streetcar or trolley car

__ Subway or elevated

__ Railroad

 

However, any changes to these three categories (or even collapsing these to a single "rail transit" category) will, if ultimately approved for testing, require a formal and carefully-controlled "ACS content change" test to be conducted by the Census Bureau in 2013 and 2014.  So this is a very big deal.  If three rail-related categories are maintained, here is one approach under consideration for future testing:

__ Streetcar or trolley rail

__ Subway, metro, or light rail

__ Commuter railroad or Amtrak

 

Or maybe a variation that makes it clear(er) each of these choices refer to a rail transit mode:

__ Rail - streetcar or trolley

__ Rail - subway, metro, or light rail

__ Rail - commuter railroad or Amtrak

 

If you have any comments about what seems to make the most sense from the viewpoint of a future ACS respondent and/or transportation data analyst, please send me an email and I will summarize all comments received in a future email to this listserv (along with your name as the author, unless you wish to be anonymous).  But feel free to reply directly to this listserv with your observations!
