What Is Road Safety Audit (RSA)


Road Safety Audit (RSA)

Road safety audit is a systematic and proactive approach for  checking the road safety implications. It could be done for a proposed road or an already existing road.

The road safety audit is commonly used in the United Kingdom, Australia and the United states. It is mainly done by a team of competent professionals which could include highway safety engineers, highway design engineers, law enforcement, etc.


It is used to identify road safety problems and to suggest measures to eliminate or mitigate any concerns.

In carrying out this audit, two important questions should be asked:

  • Who could be hurt if collision occurs on this part of the road and how could that happen?
  • What can be done to either reduce the potential for that collision or reduce its consequence?
