they shoud\ld just learn from vietnam or other country, put countdown timer till next light changes.
Historical studies had shown that Singaporeans, renowned for peculiar kiasu and kiasi behaviour, applied the brakes and were prepared to stop while others accelerated when the countdown timer showed two seconds to red, leading to a greater likelihood of rear-end collisions.

RELIABILITY OF RED-LIGHT CAMERAS ENSURED BY POLICE

7 Feb 2008
We refer to Mr Wong Bheet Huan's letter "Help motorists not to beat the red light" (The Straits Times, 26 January 2008) and Mr Vincent Lim How Siang's letter "Standardise amount of 'green' time at junctions (The Straits Times, 30 January 2008).
Police assure Mr Wong Bheet Huan that we regularly maintain and upgrade our red-light cameras to ensure their reliability, accuracy and effectiveness. Each red-light camera is only activated when the traffic light turns red and is not triggered by the backup flash light mentioned by Mr Wong. In addition, all photos taken by the cameras are meticulously viewed and checked by officers before tickets are issued to offenders.
LTA would also like to clarify that the amber period can be in the form of an amber light (junction without green arrow), flashing green arrow (junction with green arrow) or amber arrow ( Junctions with Red Amber Green). The amber period is always fixed depending on the approach speed of a junction. If motorists travel within the speed limit of the road, the period given would allow them to stop in time if they see the amber light from a distance. If they see the amber light near the stop line, the time given would also allow them to clear the junction safely.
LTA has carefully considered the installation of countdown timers for traffic junctions. A trial was conducted along Rochor Road near Bugis Junction to assess the behaviour of local motorists towards the countdown timer. Over a period of one year, there was a reduction in the number of vehicles beating the red light during the initial four months of the trial. However, after the initial four months, motorists behaviour returned to when the countdown timer was not installed.
Varying motorist behaviour was observed when they approached the junction. For example, when the countdown timer showed that two seconds remained before the traffic lights turned red, some motorists applied the brakes and were prepared to stop while others accelerated. These observations suggest that the countdown timer may result in a greater likelihood of rear-end collisions at traffic junctions. Studies conducted overseas have also confirmed this similar observation.
While we have not installed such countdown timers on our traffic light junctions due to safety concerns, LTA is actively seeking new technologies that will assist motorists and will implement such technologies when possible.
Police's aim is to reduce accidents and not to issue tickets. Red-running is dangerous. Motorists who ignore traffic signals put themselves and other road users at great risk. For their own safety and the safety of other road users, motorists should adhere to all traffic rules and regulations, whether or not there are cameras or police around.
We thank Mr Wong for sharing his view.

COUNTDOWN TIMERS WERE TESTED BUT ...

9 Jun 2012
We refer to the letter from Mr Charles Ong Hai Beng on the traffic light system (“Countdown Timers for Motorists too?”, TODAY, 4 Jun 2012).
Singapore's traffic light system operates on the Green Link Determining System, or "GLIDE", where the duration of green time at a traffic light junction can be varied according to traffic demands, thus allowing for smoother traffic flow. This therefore makes it operationally challenging to implement countdown timers at traffic junctions.
We had studied the installation of countdown timers at traffic junctions. In 2003, we conducted a trial at the junction of North Bridge Road and Rochor Road to assess the behaviour of motorists towards the countdown timer. The trial showed that motorists displayed varying behaviour when they approached the junction as the countdown timer approaches zero and the lights turn red.
Some motorists applied the brakes to stop while others accelerated to beat the light. These observations suggest that the countdown timer may result in a greater likelihood of rear-end collisions at traffic junctions. Studies conducted overseas have also confirmed this observation.
To enhance safety at traffic light junctions, LTA has set a few seconds of an all red period as a buffer in between each change of the traffic light. This is consistent with international practice.
We thank Mr Ong for the opportunity to clarify.
