Acoustics-based street light control

A computer system for acoustics-based light source control of a lighting system, wherein the lighting system is configured to illuminate a path, 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, wherein the trajectory corresponds to a length of the path and is associated with a direction of motion of the sound source along the path;
• identifying one or more light sources of the lighting system positioned adjacent to the determined spatio-temporal trajectory based on the topography of the path at the positions of the sound source, the positions of the one or more light sources along the path, and the determined spatio-temporal trajectory;
• and
• in response to determining that a distance between the sound source and the identified light sources does not exceed a predetermined threshold,
• energizing the one or more light sources to illuminate the length of the path ahead of the sound source.
