Q8: Alternative Travel Mode 15/23 • Retained Multiple Responses (15/23)<br />

Q11: Reason for Choosing<br />

Heartland Flyer for Trip<br />

27/23 • Retained Multiple Responses (27/23)<br />

Q18: Employment Status 6/25<br />

• Retired (2/0)<br />

• Retained Multiple Responses (4/25)<br />

For access and egress modes <strong>of</strong> travel, researchers identified <strong>the</strong> primary mode <strong>of</strong> travel<br />

based on <strong>the</strong> multiple responses given in tandem with o<strong>the</strong>r information on <strong>the</strong> survey form; for<br />

example, if a respondent that was going to Fort Worth marked commuter train, local transit, and<br />

walked, researchers concluded that person was using a commuter train to go to Dallas first, <strong>the</strong>n<br />

<strong>the</strong> o<strong>the</strong>r modes. For o<strong>the</strong>r questions, such as trip purpose, alternative travel mode, and reasons<br />

for choosing <strong>the</strong> Heartland Flyer, <strong>the</strong> recoding <strong>of</strong> multiple responses was quite difficult.<br />

Additional Corrections<br />

In addition to <strong>the</strong> corrections for “o<strong>the</strong>r” and multiple responses in <strong>the</strong> data set, several<br />

o<strong>the</strong>r opportunities existed throughout <strong>the</strong> data set to reduce inaccuracy error. Two issues in<br />

particular, one related to <strong>the</strong> passenger rail trip frequency and <strong>the</strong> o<strong>the</strong>r related to <strong>the</strong> passenger<br />

boarding and alighting station, <strong>of</strong>fer interesting lessons that can be applied by researchers or<br />

analysts to future on-board surveys <strong>of</strong> intercity passenger rail routes.
