Acoustics-based street light control

A computer system for light source control, the computer system comprising:

• one or more computer processors, one or more computer-readable storage media, and program instructions stored on one or more of the computer-readable storage media for execution by at least one of the one or more computer processors, the program instructions, when executed by the at least one of the one or more computer processors, causing the computer system to perform a method comprising:
• detecting, by one or more acoustic sensors, sounds emitted by a sound source from positions located along the path;
• determining a velocity of the sound source with respect to a point on the path based on the detected sound emissions;
• determining a spatio-temporal trajectory of the sound source based on the determined velocity and a topography of the path at the positions of the sound source;
• identifying one or more light sources of the lighting system positioned adjacent to the determined spatio-temporal trajectory;
• and
• energizing the one or more light sources to illuminate the length of the path ahead of the sound source.

A computer program product for light source control, the computer program product comprising:

• one or more computer-readable storage devices and program instructions stored on at least one of the one or more computer-readable storage devices for execution by at least one or more computer processors of a computer system, the program instructions, when executed by the at least one of the one or more computer processors, causing the computer system to perform a method comprising:
