Testing Modification to Travel Mode Question

Current Question 31 – Travel Mode

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 ➔ SKIP to question 39a Other method

Proposed Question 31 – Round 1 Testing

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

• ne used for most of the distance.

__ Car, truck, or van __ Bus or trolley bus

__ Subway or elevated rail __ Commuter or long-distance railroad __ Light rail, streetcar, or trolley

__ Ferryboat __ Taxicab __ Motorcycle __ Bicycle __ Walked __ Worked at home➔ SKIP to question 39a __ Other method

Testing Modification to Travel Mode Question

Proposed Question 31 – Round 2 Testing

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

__ Subway or elevated rail __ Commuter rail or long-distance train __ Light rail, streetcar, or trolley

__ Ferryboat __ Taxicab __ Motorcycle __ Bicycle __ Walked __ Worked at home➔ SKIP to question 39a __ Other method

Proposed Question 31 – Final Proposal

How did this person usually get to work LAST WEEK? Mark ONE box for the method of transportation used for the most distance. __ Car, truck, or van __ Bus or trolley bus

__ Subway or elevated rail __ Long-distance train or Commuter Rail __ Light rail, streetcar, or trolley

__ Ferryboat __ Taxicab __ Motorcycle __ Bicycle __ Walked __ Worked at home➔ SKIP to question 39a __ Other method

Cognitive Testing Findings

• Selecting multiple boxes regardless of

instructions

• Respondents identified their local transit

system by its local proper name rather than generic name

• Tendency to default to “commuter rail”

Testing Modification to Question on Time of Departure for Work

Current Question

What time did this person usually leave home to go to work LAST WEEK? Hour __ Minute__ a.m. p.m.

Proposed Version 1

What time did this person usually arrive at work LAST WEEK? Hour__ Minute__ a.m. p.m.

Proposed Version 2

LAST WEEK, what time did this person’s trip to work usually begin? Hour__ Minute__ a.m. p.m.

Cognitive Testing Findings

• Time of arrival

– Heavy heaping – Reporting what time work starts – Confusion about what ‘arrival’ means – Not especially sensitive

• Time trip to work usually begins

– Heaping – Not especially sensitive

Content Test - Looking Forward

January/February 2015

• Topical subcommittee leads provide final recommendations

for question wording for field testing March through June 2015

• Conduct cognitive testing to identify any modifications

necessary for Group Quarters and Puerto Rico (neither are included in the field test) March through May 2016

• Conduct data collection for the field test via Internet, mail,

CATI, and CAPI (Content Follow-Up Reinterview continues into June) January 2019

• Implement revised content into the production ACS

for two adults to walk side by side?
