Details of Selected Projects

Capacity Building in Road Safety: Bhutan (Asian Development Bank / Royal Government of Bhutan)
The purpose of the technical assistance project was to review and improve the existing National road safety policy and to introduce and build local capacity in the road safety audit process in Bhutan. Priority was aimed at building the capacity of the Department of Roads (DoR) to manage and incorporate road safety into its design processes. This would provide sustainability for the implementation of road safety throughout the DoR. Study tasks included:
  • Reviewing and updating road safety policy and institutional capacity building in road safety
  • Preparing Road Safety Audit Manual, Road Safety Audit Instructor’s manual, Road Safety Audit Training Course Notes and Standard Road Safety Audit Report
  • Developing a road safety strategy and audit program for Bhutan Government
  • Reviewing Road Signs & Pavement Marking manual
  • Prepared and presented road safety audit training course for local staff, including a National Road Safety Workshop
  • Undertook road safety auditing of several projects including ADB’s ‘piggy-back’ Road Network Project



Westlink M7 Motorway Road Safety Audits (Abigroup - Leightons CPB Joint Venture)
The M7 Motorway is a 40 km long major urban motorway in western Sydney and forms part of the major arterial road network in the Sydney region. Samsa Consulting conducted road safety audits during the detailed design, traffic management schemes, local road projects and pre-opening stages for the entire M7 Motorway project including training for site engineers. Ongoing existing conditions audits and safety reviews are also being undertaken as part of the requirements to ensure safety is maintained along the motorway and associated shared path, the longest of its type in the Sydney area.

The road safety audit process included road safety planning, audit programming and education, various road safety assessments and advice with respect to both the main alignment of the motorway as well as local road works associated with the project. The project involved considerable road safety expertise, traffic planning and transport integration. The ongoing safety audits and reviews have focussed on the assessment of motorway and shared path hazards post-opening, and have included a shared path engineering risk assessment.


Sixth Road Project Capacity Building Component: Philippines Road Safety Strategy (Asian Development Bank - Philippines Government Department of Public Works & Highways)

The purpose of the project was to improve the traffic accident prevention program of the Department of Public Works and Highways (DPWH) in the Philippines. Priority was aimed at building the capacity of the DPWH to manage road safety as a key organisational business function. This would provide sustainability for the implementation of road safety throughout the DPWH. Study tasks included:

  • Organising and conducting the Road Safety Infrastructure Improvement Investigations program of 35 hazardous sites throughout Philippines, including crash data analysis, site investigations, and recommendations of treatments and reports
  • Setting up Hazardous Location Investigation policies and procedures for future use by DPWH personnel
