“…Ismail et al [12] described a novel technique for conducting road safety analysis using an automated video analysis system based on four steps: data collection, camera calibration, extraction of road user tracks, and calculation of conflict indicators, and using computer vision techniques to automatically analyze pedestrian-vehicle conflicts proved to be feasible. Basbas et al [13] obtained indicators such as the length of the pedestrian street, effective width, and average pedestrian walking speed through field measurements and used the Viswalk pedestrian traffic simulation software to evaluate the current status of the pedestrian street. Gruden et al [14,15] obtained real-world information by video footages shot by cameras, set in order to cover the whole area of interest, and elaborated real-world information via a semiautomatic detection and tracking software to achieve trajectories and then constructed different pedestrian microscopic simulation models based on real data.…”

Using motion unit tracking technology, the pedestrian motion parameters were extracted from the monitoring video data at the ticket gate facilities in subway stations and the indicators of the lane change behavior were determined. The pedestrian lane change behavior spectrum of ticket gate facilities in subway stations was constructed from the three elements of types of ticket gate facilities, pedestrian flow, and lane change behavior, and the quartile method was used to determine the upper and lower thresholds of the indicators. The results showed that when the pedestrian flow was (5, 10] ped/min, the average values of displacement, distance, and cumulative side shift distance were the largest and the thresholds were the largest. When the pedestrian flow was (10, 15] ped/min, pedestrians generally adopted a faster walking speed to change lanes. With the increase of the pedestrian flow, the average value of the change in direction of the movement increased and the longitudinal distance at the gate-type ticket gate facilities was greatly affected by the pedestrian flow. The number of lane changes was generally once. The research results can provide a basis for scientifically setting up ticket gate facilities and reducing congestion risks caused by abnormal lane change behavior.

“…The first two objectives of the study were the focus of Phase 1 which aimed to determine and classify factors influencing pedestrian performance. A total of 56 factors were initially listed after a thorough review and evaluation of several established and relevant concepts tackling the pedestrian level of service [3,8,18] and walkability [12,19,20]. Cause-and-Effect Analysis was then employed to explore further the underlying causes which affect pedestrian performance.…”

“…There are several methodologies used for the calculated PLOS. However, this study utilized pedestrian space from the Highway Capacity Manual (2000) as the basis for the objective calculation of PLOS due to the following reasons: Pedestrian Space is considered one of the most widely used measurements in the context of PLOS [8], and Pedestrian Space is considered as one of the predictors of pedestrian performance as it is deemed statistically significant in the context of this study. The calculated PLOS showed positive indications based on the presented information as it reached the acceptable service rating.…”

“…Traditional transportation planning tends to undervalue the importance of considering walkability, precisely the qualitative characteristics of walking as perceived by pedestrians [7,8]. In fact, several studies proved that those factors could also contribute to the pedestrian level of service [8], and can actually be the key answer that may potentially encourage individuals to use it [9]. In the analysis of Amprasi et al (2022), comparing micro-simulated PLOS to user perception, the study led to an interesting result: contrary to the high level of service calculated through simulation models, a significant number of pedestrian users still feel uncomfortable and unsafe.…”

The importance of non-motorized movements, explicitly walking, and its corresponding impact on social, economic, and environmental aspects has always been overlooked due to the convenience brought by motorized vehicles. An automobile-dependent society mirrors the rise and worsening of several transportation problems, such as road-wide traffic congestion, massive fuel consumption, and excessive CO2emissions. In response to these aggravating situations and in support of various national and international calls, the main objective of this study was to extract the significant factors influencing the pedestrian level of service and walkability and to subsequently develop a predictive mathematical model for evaluating pedestrian conditions. Factors influencing the pedestrian level of service and walkability were initially identified through an extensive review and evaluation of existing studies, literature, and other relevant resources. A cause-and-effect analysis was used to develop an Ishikawa Diagram tackling pedestrian performance. The finalized factors were incorporated into the development of the Pedestrian Performance Assessment Questionnaire (PPAQ), which was utilized for data acquisition. Survey responses were then subjected to factor analysis after satisfying several tests for assumptions and suitability to extract the root causes influencing pedestrian performance. The validated root causes were then integrated to form the Pedestrian Performance Audit Tool (PPAT), a tool used in evaluating pedestrian areas in Tarlac City, Philippines. Data was analyzed through ordinal regression analysis to develop the multi-objective pedestrian performance prediction model. Results showed that there are six critical predictors of pedestrian performance unified in the final mathematical model: Pedestrian Space (PS), Official’s Intervention (OI), Ambiance (A), Vibrance (V), Street Vendors (SV), and Trash Bins (TB), and is the most significant contribution of the study. The model's validity was ascertained through a confusion matrix, which resulted in an acceptable rating. The comparison between calculated and perceived values together with the use of odds ratios served as the basis for the interpretation of some of the key results and findings. Finally, recommendations were also presented which can be a basis for the development of sustainable programs and interventions for the improvement of the pedestrian system.

The aim of this article is to show how Human Factors and Ergonomics (HFE) methods can be used to improve urban public infrastructure systems in densely populated countries, such as India. In this case, we use Accimap analysis with crowd flow approaches to inform safety and policy. We demonstrate the need for sociotechnical systemic safety by a case study of accident analysis of the Elphinstone Road railway station stampede. On September 29, 2017, the Elphinstone Road, Mumbai, India, railway platform bridge stampede killed at least 23 and injured 39 other commuters who traveled through the Mumbai Suburban railway. In this study, we understand the accident as it is presented in newspaper articles. We analyze the accident by a sociotechnical accident analysis method called the Accimap. The Accimap method helps by identification of various stakeholders and their interactions in the different levels of hierarchy in a sociotechnical system. This ensures moving away from individualistic and blame‐based accounts of media reporting to a coherent sociotechnical account based on understanding the dynamics of the situation. The findings from the Accimap analysis identify the problem areas in the commuter transit system and provide recommendations. These recommendations range from commuter flow management to enforcement of rules for supporting pedestrian flow. The article concludes with an emphasis on the development of the sociotechnical dimension of public safety and infrastructure from a human factors perspective, above and beyond what is currently practiced in India.
