This report contains evaluation study of OPS Selamat 8/2016 effectiveness. The evaluation was conducted through several research projects. These projects support two main indicators of the OPS Selamat effectiveness i.e. road users’ perception on enforcement and advocacy and road users’ behavioural changes. Among the measured variables are road safety information dosage, seat belt wearing, helmet wearing, child restraint system usage, traffic volume and vehicle speed. Findings of each measured variable, according to the predetermined indicators, were presented in separate chapters. The comparative trend of road users’ perception and behavioural changes between and during OPS Selamat and baseline period was observed. As a result, it was found that there is an increase of road users’ perception on enforcement during OPS Selamat period. However, due to a lacking in advocacy activity during the OPS Selamat 8/2016, no strong associations between self-reported behaviour towards traffic regulation compliance and road safety messages can be observed. In addition, a positive change of road users’ behaviour including seat belt wearing, helmet wearing, heavy vehicle movement compliance can be perceived during the period. These findings reveal that the OPS Selamat 8/2016 has an effect on road users but it can be further improved in order to reach a satisfactory road safety benchmark. Accordingly, some recommendations are proposed to improve the effectiveness of the OPS Selamat, especially on the variables that indicate an alarming percentage of compliance.
