Formal analysis of potential road safety hazards, treatments or auditrecommendations in conjunction with sound management practices and well planned remedial programs will make a positive contribution to improving safety.

The Road Safety Risk Management represents an approach to managing safety issues on the road network and prioritizing a wide range of road safety treatments as we get back to engineering to improve road safety.

Road safety audits on unsealed roads

The vast majority of the unsealed road network in South Kalimantan has not been designed according to present design standards but developed over time from what may have been built for temporary access to hauling log and coal transportation. This means that there is a very high potential risk that roads are being built and maintained on alignments and geometric standards that not in keeping with current user expectations.

PT PCN has embarked on a Road Safety Audit in an effort to provide a duty of  care to the road users by identifying and addressing potential safety hazards. The purpose of the road safety audits was to assess the potential crash risk along the routes and identify safety deficiencies, taking into account the function and use of the roads. In particular, consistency in standard along the  routes is important to ensure that the road users' expectations of road conditions is realistic and is not challenged. In other words to remove any 'surprises' to the motorists.

The output for each of the safety audits was a list of safety issues and possible remedial treatments, with an emphasis on low cost solutions consistent with the standard of road and level of use.

The major issues that were identified by the audits related to:
• Road alignment: vertical and horizontal curvature, crossfall,and sight distance.
• Intersections: sight distance, angle of approach, signage.
• Drainage: culverts, table drains.
• Signage: messages, location of signage, visibility and legibility of
signage, sight distance to signage, sign condition, sign position.
• Delineation: guideposts, bridge markers, intersection delineation,
delineation of roadside hazards such as drains and embankments.
• Roadside: roadside vegetation, lateral clearance to roadside objects.

Many of the recommended solutions were related to maintenance practices (eg. maintaining the immediate roadside clear of vegetation to assist sight distance through curves), delineation (eg. marking culverts with guideposts), and signage (eg. installing warning signs of particularly sharp or unexpectedchanges in the horizontal or vertical alignment).

Conducting safety audits on unsealed roads will assist PT. PCN to identify and prioritize safety improvements and, subject to the available resources, address over time the many locations requiring attention.
