Abundant Karanja, a first year student studying Urban Planning at the University of Nairobi, was among the students who presented his innovation at the UoN Talent day. This is a device that uses infrared technology to detect excess passengers in Public Service Vehicles and automatically alerts the NTSA. It utilizes a counting mechanism to achieve this.

The detector counts people as they board and alight the vehicle and alerts NTSA when its overloaded.
