Road Safety Audits

INDEPENDENT, THOROUGH, CONSTRUCTIVE

The TNS team has extensive experience carrying out Road Safety Audits (RSAs) consistent with the methodology included in the Canadian Road Safety Audit Guide (the ‘Canadian RSA Guide’). We employ a customized RSA prompt list to help guide the scope of the reviews that reflects the nature of the roadways, the stage of the project, client-specific needs, policies, and standards. We apply the tenets of the Canadian RSA Guide and supplement with industry best practice related to human factors, positive guidance, universal design, and pedestrian and bicyclist safety.
