The Micro scale Emissions Modeling System is a mobile roadside utility that estimates vehicle emissions for a section of roadway. The system utilizes three laser rangefinders to estimate vehicle speed and acceleration and trigger a license plate reader (LPR) for vehicles passing through a selected lane of traffic. A record of speed, acceleration and license plate number is created for each vehicle that passes during a data collection session. The Micro scale Emissions Modeling System post-processes the vehicle records to estimate the emissions of each vehicle. The emissions estimates are based on empirically derived lookup tables provided by the ARB Planning and Technical Support Division. These tables relate vehicle emissions to speed, acceleration, and vehicle technology type. The Micro scale Emissions System was developed inside a full-size passenger van that is capable of self-contained operation on the side of the roadway. The complete system includes mast-mounted laser rangefinders, on-board processing and database computers, and a commercial license plate reader.
