Traffic Safety Audit Report - NgurahRai

  • Bali, Indonesia

  • Completed Study in 2013

R & M was retained to perform Traffic Safety Audit Report for two loop ramps on Nusa Dua - Ngurah Rai - Benoa Toll road in Indonesia. The Nusa Dua - Ngurai Rai - Benoa Toll connects airport, port, and tourism areas in Nusa Dua, Bali and is one of the priority programs of Central Government in 6 Economic Corridors. In addition to improving Balinese economy development the toll road is needed to support APEC meeting which will be held in Indonesia.


R & M's primary focus was to report on potential road safety issues and to identify opportunities to improve safety of all road users. R & M  examined the design of loop ramps 3 and 4 for design elements representing safety concerns and proposed possible recommendations to either mitigate or eliminate these concerns. Some of the key recommendations included: Rumble strips, Barrier Mounted Chevron Signs, Advanced Warning Signs, Barrier Mounted Glare Screens, Crash Cushions, and Barrier Scuppers.  

Preliminary Study of Traffic Diversion Analysis - NgurahRai

  • Bali, Indonesia

  • Completed Study in 2013

R & M was selected for this Preliminary Traffic Study of traffic diversion analysis for the Bali Toll road network.
