Form Four student Leung Yun-yee and four of her classmates have designed a computerised bus service system that could help elderly and visually impaired people catch the right bus.

Passengers press a button indicating the number of the bus they are waiting for, sending an electronic signal alerting the bus driver not to miss the stop.

A computer screen also shows waiting passengers the number of the bus stopping next.

Leung, a student of the Chang Ming Thien College in Shek Kip Mei, said that she and her teammates wanted to design something that could make people's life better.

'We thought of this bus stop because there is a centre for the blind near our school. We see blind people waiting for buses in a dangerous way, such as leaning out into the street. It's dangerous and we hope to help them,' she said.

A model of the system was exhibited yesterday at the Chinese University of Hong Kong, during the inauguration of its Centre for Robotics and Technology Education.
