It is an essential task to promote communication between vehicles and their surrounding road users to avoid potential traffic accidents. With the development of lighting technologies, it is becoming possible for vehicles to display more detailed information to other road users in an easier way. An exterior lighting system was, therefore, proposed to display warning signals from parked vehicles on the road surface to call for the attentions of cyclists. By displaying warning signals in either a flashing or an animation way, it is expected that the cyclists can be informed of the door opening and reversing actions of the parked vehicles, even when their focus is not on the vehicles. However, it is still unclear that how the cyclists will react to the displayed signals. This study, therefore, performed a field experiment with 12 participants to investigate the influences of the proposed system on the behaviors of cyclists. It was observed that the median values of the avoiding distance to the parked vehicles could be improved to the recommended safe distance when the exterior lighting system was applied, especially for the participants without driving licenses. Meanwhile, the stress of the cyclists could be reduced, and the awareness to the actions of parked vehicles could be improved while using the system. [ABSTRACT FROM AUTHOR]

Drivers with disabilities such as hemiplegia or unilateral upper limb amputation restricting steering wheel operation to one arm could encounter the challenge of stabilizing vehicles during pedestrian collision avoidance. An sEMG-controlled steering assistance system was developed for these drivers to enable rapid steering wheel rotation with only one healthy arm. Test drivers were recruited to use the Myo armband as a sEMG-based interface to perform pedestrian collision avoidance in a driving simulator. It was hypothesized that the sEMG-based interface would be comparable or superior in vehicle stability to manual takeover from automated driving and conventional steering wheel operation. The Myo armband interface was significantly superior to manual takeover from automated driving and comparable to manual steering wheel operation. The results of the driving simulator trials confirm the feasibility of the sEMG-controlled system as a safe alternative that could benefit drivers with the aforesaid disabilities.
