Abstract
Techniques are generally described related to a pedestrian safety system. One example pedestrian safety system may include a sound collector configured to collect an audio signal in an environment of a pedestrian; a processor configured to analyze the collected audio signal to determine whether the audio signal is associated with a vehicle and a distance between the vehicle and the pedestrian; and a notification device configured to notify the pedestrian when the processor determines that the audio signal is associated with the vehicle and the distance is less than a predetermined distance.
Claims19
A pedestrian safety system, comprising:
- a sound collector configured to collect an audio signal in an environment of a pedestrian;
- a processor configured to analyze the collected audio signal to determine whether the audio signal is associated with a vehicle and a distance between the vehicle and the pedestrian;
- and
- a notification device configured to notify the pedestrian when the processor determines that the audio signal is associated with the vehicle and the distance is less than a predetermined distance.
A method for warning a hearing impaired pedestrian, comprising:
- collecting an audio signal from an environment of the hearing impaired pedestrian;
- analyzing the audio signal based on the frequency and the volume of the audio signal to determine whether the audio signal is associated with a vehicle and a distance between the hearing impaired pedestrian and the vehicle;
- and
- notifying the hearing impaired pedestrian when the frequency matches a predetermined frequency and the volume is greater than a predetermined volume.
A computer-readable medium containing a sequence of instructions to warn a hearing impaired pedestrian, which when executed by a computing device, cause the computing device to:
- collect an audio signal from an environment of the hearing impaired pedestrian;
- analyze the audio signal based on the frequency and the volume of the audio signal to determine whether the audio signal is associated with a vehicle and a distance between the hearing impaired pedestrian and the vehicle;
- and
- notify the hearing impaired pedestrian when the frequency matches a predetermined frequency and the volume is greater than a predetermined volume.
