1. A method comprising:
- receiving traffic monitoring input from a road segment over a predetermined time period, the traffic monitoring input including traffic audio input;
processing the traffic monitoring input into a time-blocked signal;
classifying the processed traffic monitoring input into a predefined traffic density state, via applying a first statistical classifier;
combining the classified traffic monitoring input with other classified traffic monitoring input which is classified via at least one additional statistical classifier; and
thereupon determining a classification of the road segment over the predetermined time period into a predefined traffic density state.

Abstract
Methods and arrangements for employing roadside acoustics sensing in ascertaining traffic density states. Traffic monitoring input is received from a road segment, the traffic monitoring input including traffic audio input. The traffic monitoring input is processed and the processed traffic monitoring input is classified with a predetermined traffic density state. The classified traffic monitoring input is combined with other classified traffic monitoring input.
