Table 4 Associations between exposure to busway and changes in public transport mode share

From: Changes in mode of travel to work: a natural experimental study of new transport infrastructure

Outcome Change in public transport mode share
Decrease Increase
Unadjusted 0.82 (0.68, 0.99)* 0.94 (0.77, 1.14)
Adjusted for commute characteristics 0.90 (0.67, 1.20) 1.07 (0.82, 1.41)
Adjusted for commute and sociodemographic characteristics 0.92 (0.68, 1.25) 1.16 (0.86, 1.55)
Maximally adjusted model 0.91 (0.66, 1.24) 1.26 (0.92, 1.72)
Sensitivity tests:
S1. Including baseline 0.93 (0.63, 1.37)  
S2. Including parking 0.92 (0.66, 1.27) 1.28 (0.93, 1.76)
S3. Non-movers only 0.99 (0.66, 1.49) 1.30 (0.91, 1.86)
S4. Perfect diaries only 1.03 (0.71, 1.48) 1.43 (1.00, 2.05)
  1. Multinomial logistic regression with ‘no change’ as the reference outcome category
  2. Exposure to the busway was defined as the negative square root of the distance from home to busway
  3. Values tabulated are relative risk ratios (95 % confidence intervals)
  4. *p < 0.05; **p < 0.01
