Measuring the driver exposure to the light pollution

Résumé

The paper presents an embedded system, dedicated to the measurements of the light pollution from the point of view of a driver. The literature relates many measurements based on CCD cameras and the field of luminance, but the authors search to obtain a global characterization of the light pollution, obtained from a vehicle. The visual stress of the driver and his response can be measured, but this system can also measure the quality of the street lighting, including the entire luminous environment, that is the most useful and important parameter. The measurement chain is based on a TCS34725 color sensor, which has RGB and clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The sensor has an extended 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use to measure glare but also dark spaces. Catalog data are available to make human eye sensitivity correction and scaling, but lab test was necessary to obtain reliable results. The sensor is connected with I2C serial bus to a Raspberry PI3 system, obtaining the mobility of the platform. A GPS receiver is also integrated, giving the possibility to locate the data on a map. Using this system in a public transportation vehicle, with a standard path, generates specific results, and it is possible to make some comparisons with other data set. Evolution in time of the street lighting could be also realized, if the measurements are done periodically, in time. With the Development of this measurements system, new information will be available about the lighting environment, including light pollution.
