R.E.A.R. (REALTIME EMISSIONS OF AUTOMOBILES ON ROAD)
Dynamic Remote Sensing Device (RSD) Technology for Live Traffic Emissions
Vehicular exhaust remains one of the largest and most difficult-to-track contributors to global air pollution. Traditional emissions testing occurs in stationary, controlled garage environments, which often fail to reflect the actual pollutants a vehicle emits while under engine load in moving traffic.
A2P Resources solves this through R.E.A.R. (Realtime Emissions of Automobiles on Road)—a specialized, tailored program designed to measure real-world, real-time exhaust emissions from fossil-fuel-based automobiles without ever stopping the vehicle.
How RSD Technology Works
R.E.A.R. deploys advanced Remote Sensing Devices (RSD) positioned across traffic lanes or highway toll booths. As a vehicle drives past the sensor equipment:
An invisible beam of ultraviolet (UV) and infrared (IR) light is passed through the vehicle's exhaust plume.
The sensors instantly analyze the light absorption to determine the exact chemical composition of the exhaust gas.
The system captures this data in fractions of a second while the vehicle is actively driving under real-world conditions, completely eliminating traffic disruption or manual checkpoint bottlenecks.
Emissions Constituents Measured:
The R.E.A.R. system captures a highly detailed chemical profile of every passing exhaust plume, including:
Particulate Matter: PM1, PM2.5, PM10
Nitrogen Compounds: NO, NO2, NH3 (Ammonia)
Combustion Gases: CO (Carbon Monoxide), SO2 (Sulfur Dioxide), HC (Hydrocarbons), O3 (Ozone)
Empowering Planners & Policymakers
By capturing thousands of emission profiles per day, R.E.A.R. transforms how cities manage vehicular pollution. It is an invaluable tool for:
Transport Authorities & Pollution Control Boards: Identifying the small percentage of "gross polluters" (heavy commercial vehicles and poorly maintained cars) that contribute to the vast majority of urban road emissions.
Policy Formulation: Providing irrefutable, hard data to support the implementation of Low Emission Zones (LEZ), commercial vehicle phase-outs, and targeted EV transition mandates.
Smart City Traffic Management: Enabling data-driven routing of heavy logistics traffic away from densely populated residential and hospital zones during peak emission hours.
