Analysis of influencing factors and anti-pinch measures for door pinch accidents in conventional public transportation

A safe and convenient bus service is important for improving the bus mode share. However, during the morning and evening peak travel periods, hurrying passengers may get caught in closing doors when they squeeze into a bus. We conducted a survey of bus door pinch accidents that occurred in Harbin, China for the past five years to investigate the factors contributing to such accidents. A total of 1465 samples were collected to explore the effects of passenger age, gender, and other factors on pinching accidents. The results of the logit regression analysis revealed that all six influencing factors significantly affect the occurrence of door pinch accidents. Juveniles, females, and slow-moving people are more susceptible to pinch accidents. Additionally, situations such as door congestion, rushing to get on or off the bus, and inappropriately located cameras increase the likelihood of such accidents. To further investigate the effects of variables on different scenarios, the accidents were classified into four categories based on their occurrence process and object and analyzed using multiple logistic regression. The results show that juveniles and females are more likely to be involved in accidents in which objects are pinched, slow-moving people are more prone to be pinched while boarding and rushing to get on or off the bus, and congestion at the doors increases the probability of all four types of pinch accidents. Therefore, we recommend modifying the door position, eliminating the front door seat, and adjusting the handrail distribution to alleviate door congestion. Moreover, the door-closing warning sound must be amplified to remind passengers that the door is about to close, potentially reducing the number of pinching accidents caused by rushing to get on or off the bus.
