Railroad crossing warning system for enhanced route planning

A system for reducing vehicle traffic delays at railroad crossings, comprising:

• a computer;
• and
• an application executing on the computer that:
• processes a series of sounds received by a microphone proximate the computer,
• performs Fast Fourier Transform (FFT) analysis on the series of received sounds,
• determines, based on the analysis, that a first received sound exhibits at least a first frequency, and
• instructs a server, via a cellular module and based on the determination, to transmit a broadcast.

A method of reducing vehicle traffic delays at railroad crossings, comprising:

• a computer equipped with a communication module receiving from a proximate microphone a plurality of electronic signals representing sounds captured by the microphone;
• the computer identifying a first electronic signal as associated with at least a first frequency exhibited by a first sound of the plurality of sounds;
• and
• the computer, based on the identification, transmitting via the module a first message to a backend server.

A system for detection of trains at railroad crossings, comprising:

• a field-deployed detection and reporting device comprising:
• a microphone;
• a communication module;
• a microprocessor;
• and
• an application executing on the microprocessor that:
• receives data describing sounds captured by the microphone,
• wherein the sounds captured by the microphone include a plurality of frequencies,
• filters the plurality of the frequencies of the sounds to isolate different frequencies,
• identifies frequencies corresponding to a railroad crossing warning bell, and
• transmits, based on the identified frequencies and a formula, a first message via the communication module.
