Group 1: Historical Context - The "stand on the right, walk on the left" practice was promoted in major cities like Beijing and Shanghai over 20 years ago, gaining traction during events like the Beijing Olympics and Shanghai Expo [3][5]. - Initially, the practice was not widely adopted, with many people standing side by side on escalators until a cultural shift occurred [3][4]. Group 2: Public Sentiment and Behavior - Many commuters support the "stand on the right, walk on the left" practice primarily for time-saving reasons, as it allows faster individuals to pass [5][9]. - However, there is a growing debate among the public regarding the efficiency and safety of this practice, with some expressing concerns about the dangers of walking on escalators [16][18]. Group 3: Safety Concerns - Studies indicate that walking on escalators can be hazardous, with a significant number of accidents occurring due to falls or collisions [28][29]. - The design of escalators is not intended for walking, as they are classified as "special equipment" and have different step dimensions compared to regular stairs, increasing the risk of accidents [20][24].
