[53] [54] [55] The automaker conducted a test with a group of the visually challenged at Milford Proving Grounds in order to evaluate the audible warning systems on the Volt when a pedestrian is in the car's proximity. The system uses the car's horn to emit a series of warning chirps, like a low tone of a horn, enough to provide an alert but ...
Compared with other types of warning devices, the effectiveness of the embedded pavement flashing light system seems to be high. [4] When approaching a crosswalk with an embedded pavement flashing light system, drivers are more apt to slow down and yield to pedestrians than when drivers approach a crosswalk with another type of lighted warning device.

The pedestrian signal heads operate normally, displaying an upraised hand (don't walk) aspect during the time that vehicles have the right of way. [4] When a pedestrian activates the beacon by pushing the pedestrian call button, the HAWK beacon sequence is started. First with flashing yellow, then steady yellow, and finally steady red over a ...
Waymo has a similar system in which the vehicle can warn a pedestrian, emit a siren, or take evasive maneuvers, such as finding a different route. GM's Cruise faced a major roadblock last year.
Under certain conditions, if the PCAM systems determine that the possibility of a frontal crash with a pedestrian or bicyclist is high, it prompts the driver to take evasive action and brake by using an audio and visual alert. If the driver notices the hazard and brakes, the system may use some sort of brake assist to provide additional braking ...
A set of yellow truncated domes on the down-ramp in a parking lot. Tactile paving (also called tenji blocks, truncated domes, detectable warnings, tactile tiles, tactile ground surface indicators, tactile walking surface indicators, or detectable warning surfaces) is a system of textured ground surface indicators found at roadsides (such as at curb cuts), by and on stairs, and on railway ...
The lane departure warning system will make automatic steering adjustments to help ensure that the vehicle maintains its lane in case the driver fails to react. Driver Monitoring System was introduced on the Lexus LS. The rear-end pre-collision system includes a rearward-facing millimeter-wave radar mounted in the rear bumper. [56]
The system in turns warns the driver with acoustic tones, the frequency indicating object distance, with faster tones indicating closer proximity and a continuous tone indicating a minimal pre-defined distance. Systems may also include visual aids, such as LED or LCD readouts to indicate object distance.
