Police have shortlisted 140 roads where speed cameras might be installed

According to The Straits Times, in addition to expressways and main roads, the list of potential areas where speed cameras will be installed, includes roads in HDB estates like Choa Chu Kang, Pasir Ris, Tampines, Woodlands and Yishun - in addition to residential enclaves such as Serangoon Garden and Picadilly Circus near Seletar.

The police told the English daily that the study would aid to provide information such as optimal allocation of cameras, and where to place the speed cameras for effective deterrence. Moreover, the police are also looking for experts to study accident trends on 200 roads, including ones that are shortlisted.

The move follows a six percent increase in the number of speeding tickets issued, from 245,427 cases in 2012 to 260,512 last year.

The police declined to reveal the number of permanent speed cameras currently in use, or how many new ones would be installed - excluding almost 260 digital red light and speed cameras which will be installed by the first half of 2015. As of May 2012, there are 18 permanent speed cameras, in addition to 56 well-known spots where the police utilise portable speed cameras to nab offenders.

While most residents and experts, including a veteran road engineer, support the expansion of the speed camera network, Mr. Alvin Tan, a Senior Vice President of a Singapore Exchange-listed firm believes sufficient warning must be given to motorists to slow down. He explained, "The purpose of speed cameras is to encourage safe driving, not collect fines from unsuspecting drivers. Without sufficient warning, drivers who brake suddenly when they see the speed cameras can cause accidents, and that is dangerous".
