Table 5 Accelerometer-derived number of steps taken in trips according to the main modea used in the trip

From: Combining sensor tracking with a GPS-based mobility survey to better measure physical activity in trips: public transport generates walking

Classifications of trips according to the mode Number of steps taken per trip: median (10th and 90th percentiles) Cumulated number of steps in trips per individual per 8 h of accelerometer wear time:b median (10th and 90th percentiles) % of trip-related steps taken attributable to these trips
Crude classification
 Entirely walked trips 425 (4, 1587) 554 (61, 2176) 43.2
 Other active modes 283 (41, 1007) 0 (0, 123) 3.3
 Public transport 1352 (499, 2453) 397 (0, 1913) 37.3
 Private motorized 86 (10, 453) 120 (0, 549) 11.7

  1. RECORD MultiSensor Study, 284 participants, 8728 trips, 20,564 trip stages
  2. aWe consider the steps accumulated over the entire trip (including with non-walking modes and during transfer episodes)
  3. bThe overall number of days of mobility survey could not be used as the denominator as there is nonwear of the accelerometer within it. As a consequence, we chose as the denominator the number of units of 8 h of accelerometer wear time
  4. cLong distance train and plane
