The lowdown on the AES by Shahanaaz Habib

The AES may not be the only solution to reducing road accidents but it can be an effective initiative in the long run.

IT was supposed to be the solution for many of Malaysia’s road safety woes, but the Automated Enforcement System (AES) has instead drawn mixed reactions. The latest was the Selangor state government’s decision to block the installation and implementation of the system until an independent valuator reviewed if the Transport Ministry has “holistically” considered all necessary procedures.

Transport expert and Universiti Putra Malaysia vice-chancellor Datuk Dr Radin Umar Radin Sohaidi, who came up with the AES concept when he was heading the Malaysian Institute of Road Safety Research (Miros), shares his views on the automated system.

> Is the AES really the way to go to bring down road accidents and fatalities?

It is one of the proven ways to tackle speed-related crashes and red light-running crashes in any country. In Malaysia, we have about 1,500 deaths, 5,000 serious injuries, 12,000 slight injuries, (and) around 50,000 damage-only crashes related to speed and running red lights every year on our roads. Many are just victims like you and me.

> What are the pros and cons of the AES?

AES offers a 24-7 enforcement opportunity, provided it is set up properly and there is good acceptance by all. At the same time, it eliminates discretion and corruption. It has the potential of reducing about 30% to 40% of speed-related and red light-running “Killed and Seriously Injured” (KSI) cases (around 2000 less KSI) per year. The key success factor is in the details, particularly on parameter settings and engagement with the public. The public should look at it from the public safety point of view rather than revenue generation. 

> Is there an alternative and different system that is comparable and just as effective? If so – what and how does it work?

Traffic calming like speed control devices such as humps, rumble strips, speed tables, super elevations, and delineation have also been used. However, they are only appropriate under certain conditions. In addressing speed-related and red light-running cases, the AES would be the best option.

> Why do you think there is so much objection and resistance on the AES if the objective is to save lives and that those who do not commit traffic offences do not need to pay?

First, it has been politicised and the general election is coming near. Second, the parameter settings were not done properly.

Third, the public have not been properly informed. Fourth, there have been many spinners with the wrong knowledge and information, for example that AES is saman ekor – which is not the case. Fifth, it is perceived as being subcontracted to a private company. Somehow, it is not promoted as a life-saving initiative. Hence, there is a need to get it right.

> How surprised are you at the resistance to the AES?

Not surprised. This is the normal cycle and has also been experienced by other countries.

> What should or could be done to gain public confidence and acceptance of the AES?

Site verification must be carried out. What is on the map must be on the ground. Collision mechanisms and road user movements (RUM) must be attributable to speed-related and red light-running crashes. We need the RUM and collision diagrams to verify this.

Parameter settings must be carried out. Among the parameter settings for red light cameras are phasing, timing, inter green, dilemma zones, viability, layout configurations, lane balance, trapped lanes and others. All of these must be properly set first, before the camera is installed. This is to ensure that red-light running is not due to poor design of the intersection. For example, we can’t blame the road user for beating the traffic light due to frustration (waiting for more than three cycles of red light).

For speed cameras, the parameter setting would be speed consistency within a 5km section, speed change, approach speed, 85th percentile speed, and design speed, among others. If more than 15% are caught overspeeding, it indicates that the posted speeds are not appropriate. Signage is important, too. Finally, outcomes of the AES in saving lives must be communicated.

> What is the best way to reduce accidents, fatalities and mishaps?

Many interventions but each one depends on the (individual) crash characteristics.
