Crossroads

2017

Java algorithm

At crossroads, people make choices. At life’s turning points, people move in different directions. At each of the six crossroads marked on the map, I recorded the sound of countless vehicles heading towards different directions for a minute. These recordings are, thus, collections of choices. I picked intersections on Chang’an Avenue for it runs directly in front of Tiananmen Square and is considered the most important road of Beijing.


I made an algorithm which analyzed the sound input of the loaded recording. The colors were determined by the frequency of the audio as I mapped the frequency input to the RGB scale. The sizes of the circles were determined by the audio level of the file. Given the brightness and fuzziness of the right-most graph, one can tell Guomao (the Central Business District, pictured in the lower middle) had the loudest traffic with more high-pitched noises.
