Some encounters between motorists and pedestrians turn into injuries or deaths due to excessive delay on the part of drivers, and pedestrians' impatience might lead them to opt for the rolling gap. Insights into drivers' yielding behaviour in developing countries are lacking. Meanwhile, developing countries contribute significantly to traffic deaths, particularly those in the African Region. Understanding drivers' yielding behaviour is necessary for effective interventions to safeguard pedestrians and encourage safe walking. Accordingly, by deploying a backward binary logit model, this study investigated drivers' yielding behaviour at marked uncontrolled pedestrian crossings through naturalistic observation. The results revealed that a small share of drivers, 258, were observed to yield to pedestrians, representing a 28% yielding rate in total. The model indicates that the chances of motorists yielding to pedestrians are enhanced by the following factors: pedestrian age, density, gender and traffic condition. Private car drivers had the lowest yielding rate of 18.2%, followed closely by public transport drivers. This research contributes to the discourse on drivers' yielding behaviour at pedestrian crossings with perspectives from a developing country. Further, it discusses policy implications for policymakers and enforcement agencies.</p></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0386111224000074/pdfft?md5=21b42cddcde664d1bfdd68996e76adb5&pid=1-s2.0-S0386111224000074-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response to this trend, many studies in Asian countries have examined the prevalence of motorcycles and assessed their impacts. In order to identify significant studies on motorcycles, this study conducts a bibliometric analysis of motorcycle studies in Asian countries. The data were gathered from Scopus and Web of Science databases over the entire publication period from 1971 to 2022. This study uses VOS-viewer and Biblioshiny to highlight important indicators, including source, authorship, country, institution, citation, co-citation analysis topic classifications, and keyword occurrences. A total of 2529 articles from journals and conferences were examined. The results reveal that published studies of motorcycles in Asian countries increased by an average of 22% after their initial appearance in 1971. Motorcycling studies in Asia have evolved from focusing on safety (1971–2000) to broader themes including emissions (2001−2012), the built environment's impact on energy (2013–2019), and recently towards advanced technology and urban sustainability (2020−2022). <em>IATSS Research</em> is ranked seventh with the most motorcycle articles. China, including Taiwan, has the most articles and citations among Asian countries. Based on the publication themes, the 51 years of motorcycle studies in Asia can be categorized into five clusters: accidents and human factors, traffic and policy, air pollution, motorcycle engineering and performance, and roads and technological innovation. Finally, eco-friendly fuels for motorcycles, diversity of motorcyclist behaviors in Asia, and technology-based driving safety are significant topics for future studies.</p></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0386111224000050/pdfft?md5=8c551c947b65cc1aea3a74085c9d9fbf&pid=1-s2.0-S0386111224000050-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139676009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This problem has become a concern in urban and industrial environments due to the characteristics of rail systems and unsafe pedestrian behaviour. Research reveals that psychological and infrastructural factors influence pedestrians' decision-making when crossing railroad lines. One of these is the convenience that leads pedestrians to cross at the nearest point. However, investigations to date only study the impact of location on the risk and severity of crashes and pedestrian rule violations. The current research is quasi-experimental, i.e., no optimisation tool has been developed to determine which crossing points pedestrians should follow. Therefore, this research develops a mathematical model for locating level crossings at railways to minimise the total weighted-walked distance. A genetic algorithm was proposed for solving the model, especially for large-size problems. The algorithm parameters were calibrated using the design of experiments and ten instances based on the characteristics of the area under study. The obtained results provide (1) the location of the level crossings and (2) the route pedestrians should follow for each origin-destination pair based on the facilities adjacent to the rail lines. A sensitivity analysis was performed using the ten instances to determine how the location of the level crossings changes with modifications in the facilities' location. Results showed that the model provides alternative solutions according to the problem's size.

This paper develops conflict-based safety performance functions (SPFs) to predict the number of traffic conflicts at the signal cycle level in mixed traffic conditions with poor lane discipline (disordered traffic conditions). 9586 vehicle trajectories were extracted from traffic video data collected from 4 signalized intersections in India. Critically interacting vehicle pairs were estimated using Time to Collision (TTC). The conventional surrogate measure is modified into a 2-dimensional surrogate approach which captures the conflicts by incorporating the vehicle dimension, heading direction, position, speed, and acceleration in the longitudinal and lateral direction between vehicles. Rear-end and side-swipe conflicts are identified at varying threshold values to incorporate severity. Rear-end conflict SPFs show that higher conflict occurrence is expected during signal cycles with more traffic volume, higher vehicle arrival speed, more right-turning traffic, and a lower platoon ratio. At severe threshold (TTC ≤ 1 s), one 1 m/s increase in speed of vehicle increases the expected number of rear-end conflicts by 6%. Furthermore, SPFs show that severe side-swipe conflicts are expected during signal cycles with more lane-changing maneuvers and right-turning vehicles. For TTC ≤ 1 s, one unit increase in the number of lane changes would increase the expected number of sides-wipe conflicts by 7.9%.

To verify the proposed framework, two road sections in India with mixed traffic conditions, located along the same road, were used. One section has no construction activity (base section) and the other has construction activity. The verification consisted of two tasks. First, to trace the movements of the vehicles, trajectory data over the study sections were developed for three traffic-flow levels, where two flow levels between the two sections were comparable. Second, the trajectory data were used to verify the proposed framework which was evaluated for the traffic streams of the two sections at the three traffic-flow levels. The results showed that smaller vehicles in the traffic stream exhibited a higher receptiveness angle (paid less attention) compared to other vehicle classes. Interestingly, the study revealed variations in safety among the three traffic-flow levels. It was observed that the traffic stream was safer at stop-and-go conditions than at other flow conditions.
