E-scooters: Still the new kid on the transport block. Assessing e-scooter legislation knowledge and illegal riding behaviour

Petya Ventsislavova, Thom Baguley, Josceline Antonio, Daniel Byrne

Summary: The use of e-scooters is increasing rapidly, but it comes with potential dangers such as collisions and illegal riding behavior. Research shows that e-scooter riders tend to be younger and more prone to engage in illegal riding behavior compared to non-users. Knowledge of current regulations related to e-scooters is limited, especially in areas like parking, speeding, and designated infrastructure. Targeted interventions and educational campaigns are necessary to improve riders' understanding of regulations and promote safer riding practices.

Analysis of pre-crash scenarios and contributing factors for autonomous vehicle crashes at intersections

Qian Liu, Xuesong Wang, Shikun Liu, Chunjun Yu, Yi Glaser

Summary: Intersections are high-risk locations for autonomous vehicles (AVs). Analyzing the pre-crash scenarios and contributing factors of AV crashes at intersections using the association rule method revealed that rear-end and lane change crashes were the most frequently occurring scenarios for AVs. The main contributing factors of these scenarios were identified, such as the location outside the intersection, traffic signal control, autonomous engaged mode, mixed-use or public land, and weekdays. Inadequate stop and deceleration decisions by the AV's automated driving system (ADS) and insufficient collision avoidance decisions in lane change crashes were important causes of these AV crashes.

Is it getting hot in here? The effects of VR headset microclimate temperature on perceived thermal discomfort, VR sickness, and skin temperature

Michael A. Rupp

Summary: This study examines the impact of microclimate temperature and standing/seated use on thermal discomfort in VR headset users. The results show that thermal discomfort decreased as microclimate temperature increased, but weight discomfort remained unchanged. Users experienced more sweating and higher forehead temperatures while standing with the lowest thermal profile. The study suggests that thermal comfort should be designed according to individual differences, duration of use, and activity level.
