TECHNICAL ANNEX 28
Gas Analyzer Source Detector Module (SDM) Corner Cube Mirror (CCM) SDM is sealed against the environment. It emits UV/IR towards the CCM. CCM returns the beams back to the SDM. RSD COMPONENTS Kinetic Conditions 3 lasers detect the passage of the vehicles and determine their speed and acceleration. High-speed video Camera It captures a digitized picture of the rear of the vehicle. The registration data of the vehicle are associated with its emission values and the technical specifications of the vehicle (fuel, age, type...) Weather Station Temperature, pressure and relative humidity Smart Sign Panels for awareness campaigns 29
