Summary: To improve the performance of a public transport system, it is important to track both boarding and alighting counts at bus stops. However, current systems often only count boarding passengers and overlook alighting counts. This research proposes a method to estimate alighting counts based on daily boarding data. The validity of the method is verified using video recordings, and it can potentially enhance scheduling algorithms to increase vehicle fleet utilization and passenger comfort in public transportation.

Summary: This paper investigates the characteristics of pedestrians' alighting and boarding process in metro stations through a controlled experiment. The study finds that pedestrians who disobey the rule of Disembarking precedes embarking have higher time headway and detouring degree, but a faster average speed. When the number of alighting and boarding pedestrians is equal, disobeying the rule has the most significant negative impact on time headway, detouring degree, and speed. Furthermore, boarding from the left side of the door improves efficiency.

Summary: COVID-19 has posed great challenges to social life and economies globally. This research uses a cellular automaton model to analyze passenger conflicts at carriage doors in the Beijing subway, and proposes separating alighting and boarding passengers into different doors as a solution to reduce bidirectional conflicts and the risk of infectious disease exposure.

Summary: This paper proposes an HPO-BP prediction model for estimating the alighting and boarding time of passengers in different types of waiting areas. The model takes into account factors such as the number of passengers, gender, luggage or children, and passenger civilization as inputs. It is trained, tested, and validated using field investigation data. The results show that the proposed model outperforms the BP neural network and other advanced algorithms in terms of prediction accuracy.

Summary: This paper uses an improved CA model to study the boarding and alighting behavior of bus passengers. It analyzes the impact of factors such as passenger loading rate, door width, and passengers boarding through the alighting door on bus stopping time. The research results can provide theoretical reference for public transportation control and management.

Summary: This study aimed to evaluate the associations between risk factors and adverse pregnancy outcomes after major trauma in pregnancy and develop a clinical prediction model. The injury severity score was predictive of adverse maternal and perinatal outcomes, with a cutoff of >8 for maternal outcomes.

Summary: This paper discusses the impact of boarding and alighting processes on the service level and evacuation capacities of urban railway stations and proposes an improved cellular automata model to describe the microscopic dynamics of these processes. The model is validated and calibrated using real data and can potentially be used for crowd management in subway stations.

Summary: Motor vehicle collisions are a major cause of head injuries, but efforts to improve automobile design and promote helmet use have significantly reduced the number of serious head injuries. Neurosurgeons have played a crucial role in preventing head injuries and saving lives in MVCs through their recommendations and research efforts.

Summary: This article presents a metro passenger detection algorithm for urban rail transit, which can effectively monitor passengers boarding and alighting. By utilizing a multiple scales attention convolution block and optical flow algorithm, the algorithm achieves competitive results in predicting passenger movement direction and detection accuracy.

Summary: The study compares injury patterns before and after easing COVID-19 lockdown restrictions in Saudi Arabia. It found an increase in trauma cases in the 30-44 age group after easing restrictions, with motor vehicle crashes being the leading cause of injury. There was also an increase in burn and violence-related injuries, as well as an increase in in-hospital mortality after the easing of lockdown restrictions.

Summary: This study proposes an agent-based microscopic simulation model for studying the boarding and alighting process of metro passengers. By simulating pedestrians moving through a bottleneck, critical model parameters were analyzed and compared with experimental data. The study found that passengers' eagerness to board has different effects on boarding and alighting efficiency.

Summary: Access to pediatric trauma care varies significantly across the United States. This study found significant disparities in access to pediatric trauma care, with most pediatric trauma centers located in urban counties and 28% of children living in counties without trauma centers. Counties with pediatric trauma centers had significantly lower rates of pediatric motor vehicle crash (MVC) mortality, while adult level 1/2 trauma centers in counties without pediatric trauma centers were associated with comparable risk reduction.
