In the two-stage transition procedure, the driver first prepares for the takeover, which is only implemented after the driver is ready. However, when the drivers should begin to prepare for the takeover, was uncertain. Although initiating a preparation request early affords more preparation time, it places greater strain on the driver. This study examined the effects of a two-stage transition procedure with preparation times of 5, 10, 20, and 55 s. The results indicated that the takeover reaction time improved when the preparation time was relatively short (5, 10, or 20 s); however, this insufficiently improved the post-transition driving performance. By contrast, with a relatively long preparation time (55 s), both the takeover reaction time and post-transition driving performance notably improved. Additionally, gaze analysis indicated that drivers were subjected to time pressure and hurried during short preparation periods. These results confirm that a two-stage transition would be more effective when initiated earlier with more preparation time.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"107 ","pages":"Pages 1062-1070"},"PeriodicalIF":3.5,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in Malaysia, the adoption rate is expected to be slower, attributed to low consumer demand. Hence, this study aims to investigate the factors influencing the behavioral intention to adopt autonomous vehicles in Malaysia using Behavioral Reasoning Theory. The study includes belief and value factors, such as openness to change and environmental concerns, as significant predictors of consumers’ reasons and attitudes towards AVs, while also examining the moderating effect of price sensitivity. Using a purposive sampling approach, 323 questionnaire responses were collected from respondents throughout Malaysia and analyzed using the PLS-SEM approach. The findings reveal that consumers’ openness to change and environmental concerns play a significant role in positively influencing their reasons for and attitudes towards AVs, while only openness to change negatively influenced their reasons against AVs. Consumers’ reasons for AVs had the most significant effect on their attitudes towards AVs, compared to other antecedents, and jointly influenced behavioral intention to adopt AVs along with reasons for AVs. Surprisingly, the study did not confirm the moderating effect of price sensitivity on the attitude-behavioral intention relationship, contrasting with previous studies. This study provides local automotive manufacturers, marketers, and policymakers with valuable insights into autonomous vehicle adoption intentions by evaluating Malaysian consumers’ openness to change and environmental concerns.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"107 ","pages":"Pages 1214-1231"},"PeriodicalIF":3.5,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Themes of capability, control, and performance were frequently linked to narratives of safety, suggesting that improvements in these areas did not compromise rider safety. Safety was conveyed as something that was being achieved through kinesthetics, better rider-motorcycle integration, and overcoming long-standing issues and discord.

In such situations, the driver’s ability to flawlessly switch between the distracting task and the driving task becomes vitally important. This narrative review discusses conditional automated driving within the framework of cognitive psychology concepts of attention and task switching. Delayed reaction time and deteriorated driving performance are attributed to cognitive overload and switch cost. Factors that contribute to driving switch cost are identified and categorized, and several road safety concerns are raised, including: i) switch cost may last for between 20<!--> <!--> s to 5 min; ii) inexperienced drivers may be unable to adequately control the vehicle after resuming manual control; and iii) low- and high-intensity non-driving tasks have a greater impact on takeover performance.

Therefore, a general two-wheeler riding behavior questionnaire (TWRBQ) was developed for the current two-wheeler traffic conditions in China, and a survey was conducted in Xi’an to test the construct validity of the questionnaire. Through statistical tests and factor analyses, e-bike riders, who were not given enough attention in real-world safety management, were carefully studied. It was found that the characteristics of aberrant riding behaviors of e-bike riders were closer to those of motorcyclists. Both of them showed a much higher frequency of aberrant riding behaviors compared with cyclists. The result implicated that the behaviors of motorcyclists and e-bike riders need to be regulated more than those of cyclists. In addition, correlations were found between some attributes of riders and aberrant riding behavior factors named errors and violations, among which having a driving license for automobiles had a more significant effect on riders’ self-reported driving errors than having a driving license regardless of vehicle types. The results suggest that safety training is necessary for both motorcyclists and e-bike riders, while the level of the training should be improved.

External human–machine interfaces (eHMIs) are possible design solutions for HAVs to ensure safe interaction with other road users. Light-based eHMIs positively affected pedestrians’ trust ratings, perceived safety, and willingness to cross. However, previous studies often neglected the effect of vehicle size, although larger-sized HAVs could be potentially perceived as the more significant threat.

In virtual reality, we created a shared space traffic scenario, in which the eHMI and vehicle kinematics matched or did not match. For yielding conditions, the results showed that participants felt more aroused with larger HAVs than with smaller HAVs. Moreover, pedestrians initiated their crossing significantly earlier when both vehicle sizes had a dynamic eHMI compared to a static eHMI vs. no eHMI.

The results manifested that the use of dynamic eHMIs can effectively enhance pedestrian-vehicle communication with a large and a small HAV.
