Road Safety Management (ROSMA) is a frame work that enables Safe System principles to be applied to all projects and activities that affect the state road network.

The Safe System approach views the road transport system holistically, by seeking to manage the interaction between the road user, travel speed and the vehicle. 

Our Road Safety Management System Policy applies to any Main Roads infrastructure, maintenance, operational, policy, guideline and process activities that may influence the rate or density of fatal and/or serious injury on the state road network.

Contractors required to undertake the ROSMA process

Where specified in contractual documents; contractors will be required to ensure that a ROSMA assessment is conducted on the project. It is advisable to check with the project manager and/or roadsafety@mainroads.wa.gov.au to see what parts of the process may have been completed prior to the contract being awarded. If the ROSMA process has not yet been applied use step 1 below. If it has been applied and the treatments selected have changed please use step 2 below.

Step 1: To determine the extent to which you need to undertake the ROSMA process we need to know:

• The location of your project; and,
• If you know it at this stage, what you intend to do.

You do this whilst you are undertaking treatment selection (typically in the Select or early Develop phase) by:

Download and complete the ROSMA Project Details Template (Excel) and email it to roadsafety@mainroads.wa.gov.au.

Based on the information you've provided we will set the Road Trauma Reduction Target and assess your proposed treatments within 10 working days. We will also advise you what actions, if any, are needed to complete the process.

Step 2: If there is already a Road Trauma Assessment for the project but the treatments selected have changed (often happens in Develop stage), please update the assessment and send through details of the changes to roadsafety@mainroads.wa.gov.au

The Treatment Resource Guide will assist with understanding the impact of various road safety treatments.
