Air Pollution in India: Vehicles are a major contributor

Vehicles are estimated to be responsible for roughly one-third of India's particulate matter (PM) pollution and 20-35% of PM 2.5 pollution in urban areas.

Major cities like Delhi, Mumbai, and Bangalore consistently witness the highest levels of vehicular pollution due to high traffic density and older vehicle fleets.

Implementing stricter emission standards like Bharat stage (BS)-VI has helped reduce emissions from newer vehicles.

But the threat is still looming

What is Pollution Under Control (PUC) Certificate?

It is a document certifying that a vehicle's emissions fall within the acceptable limits set by local environmental authorities.

Ensures vehicles comply with emission standards to minimize air pollution.

Failure to obtain a valid PUC certificate can result in fines and legal consequences.

The validity period of a PUC certificate varies depending on the vehicle type and local regulations. Typically, it ranges from 3 months to 1 year.

Expired certificates require renewed testing and issuance of a new certificate.

Scenario of the problem (nationwide)

All these vehicles are polluting the environment everyday

Any proper solutions ???

Not yet but not late

Proposed Solution

An electronic device that can alert the driver about the PUC expiry date and immobilize the vehicle if PUC is not renewed.

This device would help to deter vehicles from polluting the environment while promoting compliance with the PUC program.

Key Components of the Proposed System

On-board Unit (OBU): The OBU would be installed in the vehicle and connected to the engine management system. It would be equipped with a master controller having USB / Bluetooth connectivity, a real-time clock and an electronically actuated relay.

Graphical User Interface (GUI): The GUI would be installed at the pollution testing center that would store PUC certificate information for all vehicles. The authorized personnel can enter the updated PUC details of the tested vehicle in to the OBU via USB / Bluetooth interface.

Proposed functionalities and flow of scheme

PUC Data Entry: The authorized personnel would enter the PUC expiry date on the OBU upon successful emission testing.
Real-time Monitoring: A real time clock (RTC) in the OBU would monitor the PUC expiry date.
Driver Alert: Visual and/or audible warnings would inform the driver about the upcoming validity end date of PUC certificate and subsequent engine immobilization. (recommended by Prof. Anil Kumar Gupta)
Engine Immobilization: If the PUC is expired, the device would trigger a safe engine shutdown upon attempting to start the vehicle. (removed as suggested by Prof. Anil Kumar Gupta)

Challenges and future scope

Cost: The cost of the OBU need to be affordable for vehicle owners.

Privacy concerns: The confidentiality of the PUC certificate data and other information must be secured.

Technical challenges: The system would need to be reliable and tamper-proof.

The system could be integrated with existing traffic management systems to provide real-time data on the location of vehicles with expired PUC certificates.
