For most engineering students, final-year projects often stay confined to classrooms or lab submissions. But for one student from Mohan Babu University (MBU), a simple idea has now moved beyond campus and onto the roads of Andhra Pradesh, where it is quietly reshaping how safe a journey can feel.

When G Srinivas Reddy, a fourth-year engineering student, began thinking about road safety, he wasn’t trying to build something flashy. Instead, he focused on a very real, everyday concern: What happens when a passenger feels unsafe during a ride?

The answer he developed is deceptively simple: a QR code.

A scan that could save time and lives

At the heart of Srinivas’s innovation is a QR code-based real-time traveller protection system, now adopted by the Andhra Pradesh Police in the NTR district. Installed inside public and rental vehicles, typically behind the driver’s seat, the system allows passengers to scan a code using their smartphones as soon as they begin their journey.

Within seconds, the passenger gains access to verified details: the driver’s credentials, vehicle registration, and trip information. But what happens next is what makes the system powerful.
