Singapore tests smart signalling for buses [free access]

November 2, 2018

The Singapore Land Transport Authority (LTA) has commenced a six-month trial of a Smart Bus Priority system, which is a new signalling system prioritising the movement of buses by either extending the green light or shortening the duration of the red light. A similar system is deployed in Australia.


The real-time data for the trial is transmitted by global positioning system (GPS) trackers installed on 56 buses deployed on Routes 98 and 99.


Upon completion of the trial in April 2019, the data collected will be analysed to determine whether the system can effectively complement existing bus priority measures such as bus lanes, B-signals for buses at junctions and bus priority boxes.
