summary

The 'Comprehensive Supervision Platform for Motor Vehicle Exhaust' integrates comprehensive management business systems such as license plate review and exhaust detection, establishes a motor vehicle exhaust data center, and performs grid processing on urban supervision areas. Based on emission factor models and road traffic data, it analyzes the emission and spatiotemporal diffusion patterns of motor vehicle exhaust. The system can provide a dynamically updated mobile source emission inventory, and can combine multiple air quality models and decision analysis models to evaluate the emission reduction efforts of motor vehicle control measures, simulate the effects of improving air quality, and provide a basis for environmental management agencies to make practical decisions, and support the refinement and scientific supervision of motor vehicle exhaust emissions. The platform has been validated through practical applications in Beijing, Macau, and other places.
