title: Exploring Factors Regarding Transit-related Walking and Walking Duration.
abstract: Transit-related walking provides a potential opportunity to promote general walking behavior, yet few studies have examined this issue. Since people's decisions tend to vary as they walk between home and transit and between transit and destination, this study separated trips made in each direction.
  
  
  
  This study identified the associations between sociodemographics and the 2-step process of transit-related walking: 1) whether transit users walked for home-transit trip or transitdestination trip, and 2) the walking duration for home-transit trip or transit-destination trip among those who walked.
  
  
  
  This cross-sectional study used the 2009 National Household Travel Survey and used the Heckman 2-step selection model by including 4042 respondents (10,105 trips) who walked all portions for home-transit trip and 3756 (8075 trips) for transitdestination trip.
  
  
  
  The mean walking duration for home-transit trips (7.60 minutes) was shorter than transit-destination trips (7.87 minutes). Hispanics were more likely to walk for both directions and had higher walking durations than did whites. Respondents living in low-income households were more likely to walk for home-transit trip, but not for transit-destination trips.
  
  
  
  This study illustrated several implications regarding to transit-related walking, such as creating short home-transit distances and targeting whites in promoting transit-related walking.
