Tesla, Inc. introduced a Pedestrian Warning System feature in September 2019 [73] that emits warning sounds when the vehicle is traveling below 19mph/32km/h. [74] In 2021 Tesla announced plans to retrofit the system onto select older Model 3 and Model Y vehicles from 2019. [75]
The pedestrian signal heads operate normally, displaying an upraised hand (don't walk) aspect during the time that vehicles have the right of way.

First with flashing yellow, then steady yellow, and finally steady red over a ...
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.

Pedestrian detection Pedestrian detection. Pedestrian detection is an essential and significant task in any intelligent video surveillance system, as it provides the fundamental information for semantic understanding of the video footages. It has an obvious extension to automotive applications due to the potential for improving safety systems.
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 ...
