Drivers will start by being warned
The city Madrid will soon launch “radars” that will measure, not the speed of vehicles, but the level of emissions of gases into the atmosphere.
The new device will work in the system adopted by the speed cameras: it will be fixed and will be fully automated, as reported in the “Diariomotor”, measuring the levels of gases emitted by the cars that pass through it.
These “radars” use a RSD+ remote sensing system: ultraviolet and infrared beams cross perpendicular the path measuring the gases emitted by vehicles passing through their radius of action.
Measurements will focus on carbon monoxide (CO), carbon dioxide (CO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2). The measurement process will in the first instance inform drivers who exceed the permitted limits, but it may result in penalties if warnings are not met.
