Overall Approach
Road Safety is fully integrated into road infrastructure management and operations
Specific road safety programs
– Safer Road Infrastructure Program
Project development & implementation
Maintenance planning & operations
Working on roads
“Safety is an integrated part of all of our road programs”
Safer Road Infrastructure Program
Program Focus
Run-off-road crashes on high-speed roads
Dangerous intersections in outer metropolitan Melbourne
Greyspot intersections
Mass action treatments
– tactile centrelines / edgelines
Route treatment approach
Innovation component (up to $3m per annum)
Project Development & Implementation
Project Planning & Scope Approval
Pre-construction
Construction
Project Completion
Road Safety Audit Policy
Road Safety Audit Stages
Project Planning & Scope Approval
1. Identify need for project
congestion, land use development, safety, special needs
2. Identify treatment options & objectives
evaluate treatments & options to identify most effective project (economic & other criteria)
3. Approval to scope & cost
4. Listing with other candidate projects for future programs
Preconstruction 1. Standards for safe roads and facilities
2. Design-phase road safety audits
3. Community & stakeholder consultation
4. Construction planning
minimise inconvenience to residents & traffic
maximise safety for workers, traffic & residents
Construction
1. Detailed work plans
minimise impact, maximise safety
2. Ongoing communications
motorists & residents
3. Ongoing safety management, inspections & record keeping
4. Stage road safety audits
5. Site reinstatement & final acceptance
Project Completion
1. Hand over for maintenance
2. Post-construction review against project objectives
3. Ongoing monitoring against project objectives
traffic volumes, delays

Specified Requirements
Safety Inspections
Day & Night Inspections
– frequency depends on importance of road
• urban freeways -> minor rural arterials
Criteria for what is a “safety hazard”, eg.
– any object in a traffic lane
– pothole >300mm diameter, 100mm depth
Specified response times
– depends on hazard & importance of road
• Object on urban freeway -> missing sign on minor rural arterial
Specified Requirements
Condition Inspections
Monthly inspection for all roads
Cover all road elements
– standard list of pavement, drainage, roadside, structure items
Criteria for what is a “Defect”
– potholes, blocked drain, long grass
Specified response times
– depends on defect & importance of road
Scheduled as routine maintenance activities

Worksite Hazard Management Worksite Hazard Management Process
Step 1 – Worksite Hazard Rating
Step 2 – Required Level of Planning
Step 3 – Hazards at the Worksite
Step 4 – Hazard Control Measures – Hierarchy of Safety Controls
Step 5 – Hazard Control Measures to be Implemented
Step 6 – Prepare and Implement Traffic Management Plan
Step 7 – Review the Traffic Management Plan in Practice
Step 8 – Carry Out the Work
Guidelines
