Vehicle Emission Plume Detection Systems

Plume chasingNew

OPCAS (On-road Plume Chasing and Analysis System) revolutionizes real-world vehicle emission monitoring. This mobile laboratory uses cutting-edge sensors to non-invasively measure pollutants including PM2.5, NOx, CO, CO2, black carbon and VOCs from any moving vehicle in under 2 minutes. Mounted on a chase vehicle, it calculates fuel efficiency via carbon balance methods (EPA-compliant) while eliminating physical installation, tracking emissions from trucks, buses and all vehicle classes.

Roadside Plume Sniffing System (RPS)

The Roadside Plume Sniffing Monitoring System (RPS-Pro) is a roadside sensor network for detecting motor-vehicle exhaust plumes. It simultaneously collects meteorological parameters and pollutant concentrations to give a deeper understanding of how pollutants disperse and evolve. Data can feed directly into smart-city traffic emission management platforms, letting city managers assess real-time traffic emissions. An intelligent vehicle-recognition system uses image recognition to accurately identify and track vehicles and, combined with emission data, evaluates the pollution contribution of di
