Road Safety Audit Stages

Road safety audit is the formal examination of existing roads, future roads or various sorts of traffic projects by any independent group of trained expertise. They examine the deficiencies in road safety. There are various stages of road safety audits.  Number of stages depends on the number of stages in a road project before completion.

  1. Feasibility study phase
  2. Preliminary design phase
  3. Detailed design phase
  4. Pre-opening phase
  5. In service phase

Feasibility Study

In feasibility study phase, trained specialist study and evaluate the results of following questions;

Technical team works on these questions step by step and at the end gives the most feasible solution possible.

Preliminary Design Stage:

Preliminary design is the second stage of road safety audits. In this stage designs of roads are carried out. As preliminary phase, therefore designing is not carried out in a very detailed. Following are road designs that are done in this phase;

Detailed Design Stage

After the completion of 2nd stage, designs are carried out in detail. Following are the road designs that completes at the end of this stage;

Pre-Opening Stage

In this phase technical audit team drive through the completed project. During drive, they observe the provision of safety level, quality, sign boards, road material and all other aspects that they took under consideration during the preliminary survey and detailed design phase. They came on the site during different weather conditions like during day time, night, etc… after the completion of survey they wrote a report on it and deliver it to the main authority.


After the pre-opening examination, road is opened for public and during that still technical team remains active and they observe the working of safety features during heavy traffic.
