accidents
A total of 93,000 counts from 75 observations resulting from five sessions per day for 5 days during three periods were analysed. There were 28,823 staircases and 64,177 elevator uses on the ground floor of two observed buildings, and no stair accidents occurred. The total visitor counts at the 3rd-month phase were lower than the baseline and 6th-month phases at both buildings (Stair and elevator use.The stair climbing rate per time slot from the ground floor in the intervention building during the baseline phase was higher than that in the control building (Change in the proportion of stair use to elevator use from the ground floor (stair climbing rate) per time slot.Effect of building.Effect of period.There was a significant difference (Change in the proportion of stair use to elevator use on the ground floor (stair descending rate) per time slot.Effect of building.Effect of period.
