    We present a new assessment method for driver visibility based on reaction time measurement and workload in real driving situations from the most relevant accident scenario involving pedestrians. The procedure was validated in a balanced trial to compare a wet flatblade windshield washing system to a conventional Fluidic nozzles system. The test cohort comprised 204 subjects who form a representative sample of German driving license holders. The average reaction time gain of wet flatblade over Fluidic nozzles is 315 ms for pedestrian detection and 270 ms for the recognition of critical traffic situations.

    A new preceding vehicle (PV) following system with a haptic communication method, Haptic Adaptive Cruise Control (HACC), is proposed. HACC addresses the intention mismatch between a driver and a conventional adaptive cruise control system in a complex environment. HACC uses the torque around the steering wheel as the interface. The driver can easily find the current PV displaying the direction of the PV with the system’s torque around the steering wheel. In addition, the driver can change the PV to another one by adding torque to resist the presented torque of the system. Driving simulator experiments showed that the HACC method reduced the collision risk when the system erroneously changed the PV suddenly, and the haptic information effectively increased the driver’s understanding of the system’s intention. Furthermore, the driver’s intention could be easily communicated to the system.
