Safety at Traffic Junctions where Discretionary Right Turns are Replaced with Red Amber Green Signals

Mr Murali Pillai asked the Minister for Transport how has the replacement of discretionary right turns with Red Amber Green (RAG) signals improved road and pedestrian safety at the respective traffic junctions where these new signals have been deployed.

Discretionary right turns help to optimise traffic flow as motorists are able to execute the turn when there is no conflicting pedestrian or vehicular traffic. This is particularly useful at junctions with low traffic. However, for junctions where there is a higher risk of accidents, LTA has been progressively introducing Red Amber Green (RAG) signals. Such junctions that have been installed with RAG signals have seen a decrease of about 40% in accidents involving right turns.

Besides RAG signals, LTA also enhances junction safety through other initiatives, such as appropriate road markings, lighted road studs, integrated pedestrian countdown timers and signs.
