It consists of activated warning signs and sensors that detect vehicles approaching an intersection, transmitting a warning signal to potentially conflicting vehicles on other approaches. The current study examines the effect of ICWS on drivers driving performance while approaching an unsignalized intersection under obstructed line of sight. Four scenarios were developed to evaluate the effectiveness of ICWS. Driving performance measures such as mean and standard deviation of speed and deceleration, and driver factors such as age and number of driving days per week were analyzed using repeated measures ANOVA. Furthermore, duration variables such as response time and speed reduction time were modelled using Weibull Accelerated Failure Time (AFT) duration model. The study insights showed statistical differences among the four scenarios for all driving performance measures. The developed model revealed that with activated ICWS, drivers exhibited longer speed reduction times and shorter response times. This implies that with the activated ICWS, drivers managed to respond to the conflicting vehicle beforehand, resulting in less abrupt braking behaviour and collision avoidance at the intersection. The study highlights the significance of ICWS and will assist traffic engineers and road safety authorities in designing and implementing ICWS at unsignalized intersections in developing world traffic.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"110 ","pages":"Pages 128-147"},"PeriodicalIF":3.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422204","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}

These systems permit drivers to temporarily disengage from the driving task. However, as long as systems are not fully automated, transitions between different levels of automation are necessary and imply shifts in the driver's role and responsibilities. For example, inattention or distraction may impair the driver's ability to take over safely in the case of system limits. Therefore, this work investigates the effect of two transition strategies - monitoring the environment and initiating a maneuver - on bringing drivers back into the loop and ensuring safe driving performance during requests to intervene in Level 3 automated systems (also referred to as take-over requests). Additionally, these strategies could be employed to keep drivers in and on the loop during transitions to lower levels of automation without requiring a manual take-over. For example, when a required driving maneuver would violate traffic rules. In a driving simulator study, 36 participants experienced a conditionally automated drive on a rural road. While participants performed a non-driving-related task (NDRT), the automated driving system approached a rear-end collision blocking the vehicle's lane. In experimental trials, the system requested drivers either to monitor the traffic scene or to decide when to initiate an evasive maneuver. Depending on traffic regulations (overtaking ban present or absent), the system could not solve the situation and issued a request to intervene, or the system could perform the evasive maneuver itself. This resulted in a 2 x 2 within-subjects design with transition <em>strategy</em> (monitoring, initiating) and transition <em>type</em> (request to intervene, no request to intervene) as independent variables. None of the transition <em>strategies</em> improved driving performance, shortened take-over time or affected drivers' gaze behavior. The transition <em>type</em> affected trust in monitoring trials: when monitoring was not followed by a request to intervene, trust in the automated driving system decreased. Results are discussed in light of the suitability of both strategies for different transition contexts.</div></div>","PeriodicalId":48355,"journal":{"name":"Transportation Research Part F-Traffic Psychology and Behaviour","volume":"110 ","pages":"Pages 163-181"},"PeriodicalIF":3.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143428274","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}

The results suggested a need for improved presentation of information, with future distracted driving content suggested to be presented visually, along with more targeted messaging for high-risk drivers such as young drivers.

In the proposed model, all TPB and TAM factors are significant, while trust emerged as the most significant factor in explaining the acceptance of AAM. Multigroup analyses offered further insights: perceived usefulness and subjective norms significantly influence young adults’ intentions, while perceived behavioural control plays a pivotal role in shaping men’s inclination towards AAM adoption. These findings not only contribute to the theoretical understanding of technology acceptance but also offer valuable practical implications for informing the design, implementation, and regulation of AAM development in the GBA and beyond.
