Using specially equipped vehicles, software and trained personnel, iRAP inspections involve detailed road surveys and data collection, focusing on more than 50 different road attributes that are known to influence the likelihood of a crash and its severity.
These attributes include intersection design, number of lanes and markings, roadside hazards, footpaths and bicycle facilities. The road inspection data underpins iRAP Star Ratings and Safer Roads Investment Plans (SRIP).
This video provides an illustration of the type of data that is collected.
