An analysis of physiological responses as indicators of driver takeover readiness in conditionally automated driving

Min Deng, Aaron Gluck, Yijin Zhao, Da Li, Carol C. Menassa, Vineet R. Kamat, Julian Brinkley

Summary: This paper analyzes the effects of takeover behaviors on common physiological indicators of drivers, including brain signals, skin conductance level, and heart rate. The results show that performing secondary tasks prior to takeover activities can decrease drivers' engagement, while higher task difficulty and traffic density can increase drivers' mental workload and heart rate. Moreover, a fake takeover alert can also affect drivers' physiological indicators. The paper also discusses the correlation between physiological data, takeover scenarios, and vehicle data, emphasizing the importance of data standardization or normalization for estimating takeover readiness.

A multi-fidelity approach for reliability-based risk assessment of single-vehicle crashes

Ziluo Xiong, Suren Chen

Summary: Road vehicles are prone to single-vehicle crashes (SVCs) under complex road geometry and bad weather conditions, posing a significant threat to traffic safety and mobility. Researchers have developed a novel multi-fidelity approach that balances simulation accuracy and efficiency for reliable risk assessment of SVCs. By using a high-fidelity transient dynamic vehicle model and a low-fidelity simplified physics-based vehicle model, the proposed approach provides accurate and efficient reliability evaluation of SVCs.

Engagement by Design Cards: A tool to involve designers and non-experts in the design of crowdsourcing initiatives

Leonardo Vasconcelos, Jean Zahn, Daniela Trevisan, Jose Viterbo

Summary: In today's world, crowdsourcing initiatives have gained wide adoption. However, sporadic use alone is not enough for success in crowdsourcing initiatives, as active user engagement is crucial. To address this, an 18-card deck was created to provide designers with domain-specific insights on boosting user engagement. Through collaborative online design workshops, valuable information was provided, leading to contributions in design research and practices in crowdsourcing initiatives, particularly in user engagement.

From Driver to Supervisor: Comparing Cognitive Load and EEG-Based Attentional Resource Allocation Across Automation Levels

Nikol Figalova, Hans-Joachim Bieg, Julian Elias Reiser, Yuan-Cheng Liu, Martin Baumann, Lewis Chuang, Olga Pollatos

Summary: With increasing automation, drivers' roles transition from active operators to passive system supervisors, affecting their behaviour and cognitive processes. This study investigates attentional resource allocation and subjective cognitive load during different levels of driving automation. The findings suggest that during automated driving, drivers allocate fewer attentional resources to processing environmental information, highlighting the importance of managing drivers' attention and cognitive load for enhancing automation safety and user interface design.

Occupational arm-support and back-support exoskeletons elicit changes in reactive balance after slip-like and trip-like perturbations on a treadmill

Stephen Dooley, Sunwook Kim, Maury A. Nussbaum, Michael L. Madigan

Summary: The purpose of this study was to investigate the effects of arm- and back-support exoskeletons on reactive balance after slip-like and trip-like perturbations on a treadmill. The study found that the exoskeletons did not significantly increase the probability of failed recovery after the perturbations, but did make balance recovery more challenging. Reactive balance differed when wearing different types and activation states of exoskeletons.

A spatio-temporal deep learning approach to simulating conflict risk propagation on freeways with trajectory data

Tao Wang, Ying-En Ge, Yongjie Wang, Wenqiang Chen

Summary: This paper introduces a method to simulate the propagation patterns of conflict risk on freeways, which can help prevent traffic accidents and improve the deployment of advanced vehicle technologies. By introducing a conflict risk index and a spatio-temporal transformer network, it is possible to effectively simulate the propagation patterns of conflict risk. Experimental results show that the model based on proportion of stopping distance exhibits robust performance, while the model based on deceleration rate more distinctly delineates spatio-temporal conflict risk heterogeneity.

Modeling the lagged impacts of hourly weather and speed variation factors on the segment crash risk of rural interstate freeways: Applying a space-time-stratified case-crossover design

Zihang Wei, Subasish Das, Yue Wu, Zihao Li, Yunlong Zhang

Summary: In traditional roadway crash studies, cross-sectional modeling methods have limitations when dealing with highly time-varying variables related to weather conditions and speed variation. This study employs the distributed lag model (DLM) and the distributed lag nonlinear model (DLNM) to investigate the lagged impacts of weather and speed variation factors on segment crash risk. The results demonstrate coherent and interpretable lagged impact patterns, emphasizing the need for considering time-series effects in future crash modeling research.
