This study aimed to define practical safety countermeasures for enhancing road traffic safety for motorcycle users (both motorcycle riders and pillion passengers) in Vietnam. To that purpose, a qualitative study design was implemented, including a series of focus group discussions and in-depth interviews based on a semi-structured format with stakeholders involved in motorcyclist safety. The participants of the focus group discussions include motorcycle riders, automobile drivers, bicycle/e-bike riders, motorcycle trainers, and policymakers to define countermeasures to enhance traffic safety for motorcycle riders from the viewpoints of different road user groups and the local authorities. Besides, in-depth interviews were conducted with traffic police officers to define the essential and urgent solutions for reducing traffic crashes related to motorcyclists. The solutions for the leading risky behaviors of motorcyclists include tactical and operational strategies for motorcycle riders. Countermeasures for regulators and authorities to reduce the leading risky behaviors include engineering interventions, enforcement solutions, and education and training countermeasures. Strategies to avoid collisions when motorcyclists ride in pairs or groups include strategies for attitude change of motorcycle riders when riding, the behaviors motorcyclists should have when riding in pairs or in groups, and the appropriate riding skills for motorcyclists while riding in pairs or groups. Innovative strategies for enhancing motorcycle rider safety include strategies for motorcycle users and strategies for regulators and authorities. Providing hazard avoidance training for motorcyclists is the most significant and urgent solution that participants suggested for Vietnamese regulators and authorities in enhancing motorcycle users’ safety. These findings imply that the riding training programs for motorcycle riders need to be adjusted and updated by traffic safety authorities, primarily focusing on hazard avoidance training to improve traffic safety for road users in general and motorcycle riders in particular.</div></div>","PeriodicalId":100131,"journal":{"name":"Asian Transport Studies","volume":"11 ","pages":"Article 100159"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679705","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}

Therefore, to analyze long-term changes in future urban forms and functions, it is necessary to consider the impact of future technological innovations, such as information and communications technology (ICT), on urban activities, too. This study focuses on telework diffusion, which is one of several technological innovations. We analyze and evaluate its long-term impact on shrinking cities using the land use and transportation model “MARS.” Consequently, it was clarified that even though telework diffusion is difficult to sustain in shrinking cities, governments and municipalities must respond to these negative aspects as telework becomes more widespread for future sustainable shrinking cities.</div></div>","PeriodicalId":100131,"journal":{"name":"Asian Transport Studies","volume":"11 ","pages":"Article 100155"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143164955","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}

However, shared bikes can also be used as a primary mode. Riding duration may be a straightforward evaluation criterion to identify the role of shared bikes. This study uses survival models to investigate the critical variables influencing shared bike riding duration with a case study of YouBike in Taiwan. The results show that a survival model with a log-logistic distribution has the best model fit, as some durations are extraordinarily long or short due to the heterogeneity of usage behavior, in which the mean duration was 22 min, but 15% had riding duration longer than 30 min. The riding duration significantly varied with the turnover rate of the station location and the rider's usage behavior based on the variable estimation results. The demand pattern of YouBike riders shows a 96% chance of having a riding duration of fewer than 30 min, dropping below 55% for longer than 90 min. The indicator expressing riding duration for same-station trips is greater than an hour, suggesting that some riders may perceive YouBike as a primary or individual transport mode. The finding also underscores the role of shared bikes in facilitating users' daily activities, such as shopping and recreation, emphasizing their potential as an interchangeable mobility option. This indicates that YouBike is a first and last-mile mode and the primary mode in some cases with longer riding duration.
