Investigation into the slope gradients for humps on railway platforms.
Gaps between the train and the platform are a major barrier for elderly and disabled passengers, and platform humps are proposed to solve this problem. Humps consist of several design factors. As an initial attempt to understand the complexity of the design factors of humps, we conducted a series of experiments on the slope and backfall gradients. In total, 45 participants with various types of disabilities were asked to walk on simulated slopes and to board or alight from the simulated train from or onto the slope. The tested slope gradients were 3.0% (1:33), 5.2% (1:19) and 6.9% (1:14) with the backfall gradients 1.5% (1:67), 2.0% (1:50) and 2.5% (1:40). It was found that the slope gradient did not largely affect performance, but would add additional difficulty for them to board/alight from the train from/onto a slope. This suggests that train doors should not stop next to the slope. There was little evidence as to the effects of the backfall gradient. The results will be used in the development of the design guidelines of platform humps.
