CRASH cushions have been placed along the Tungku Highway and Muara-Tutong Highway to improve road safety. Designed to absorb 100km/h of maximum speed impact on a split approach, the barrier will collapse upon impact and avoid serious injuries or death.
This was yesterday revealed by Haji Abdul Hamid bin Haji Matussin, Acting Assistant Director of the Department of Road, Public Works Department (PWD), in his presentation on ‘Strategies & Initiatives Towards Safer Roads’ at the afternoon session of the Road Safety Seminar 2014.
Another form of crash barrier improvement is the replacement and upgrade of old guardrails to the National Cooperative Highway Research Programme (NCHRP) Test Level 3 Guardrail System. This eliminates the hazard of protruding posts that have, in the past, proved fatal to motorcyclists upon impact, he explained.
Also introduced are Emergency Barrier Gates that provide normal guardrail functions but can be removed to allow cross carriageway passage for traffic during emergency road closures, such as the ones installed at the Sultan Hassanal Bolkiah Highway. The key for the emergency barrier gates are kept by the police.
Other additions include dedicated u-turns at the traffic light junctions of Jalan Tasek and Jalan Simpang; introduction of countdown timers at the Berakas, Kiarong and Beribi roundabout traffic lights; as well as new overhead pedestrian bridges.
Meanwhile, on the subject of Asphalt Technology, Haji Abdul Hamid noted the introduction of the Stone Mastic Asphalt (SMA) surfacing mix to the Tungku Highway and Jalan Kumbang Pasang/Jalan Gadong junction.
The mix was introduced in Brunei as of last year. Its effectiveness is currently being tried and tested, pitted against the existing Asphalt Concrete Wearing Course (ACWC) which has been used as surfacing on Brunei roads.
SMA performance features include reduced aqua-planning, better skid resistance, reduced spray, reduced deformation, reduced noise, greater stability, greater durability, longer-lasting visual impact as well as safer roads and driver satisfaction.
“We welcome feedback from the public – be it from the opinion section of the local newspapers or on WhatsApp,” he said, adding that by sharing complaints on WhatsApp or calling the hotline 123 would help to improve their service.
“Hopefully, the following day or the day after, the issues will be resolved,” he said during the question-and-answer session.
With regards to whether the introduction of ‘speed control’ or ‘rumble strips’ was safe for road users, he explained that the rumble strips are indeed safe and would effectively remind drivers to slow down their vehicles. The rumble strips are raised at 2mm, the minimum height based on international standards.
