N2  - Although road safety inspections (RSIs) are useful for identifying safety issues, their subjective nature may limit their effectiveness. In this paper, a procedure aimed at improving the effectiveness and the reliability of the RSI methodology has been defined. For this purpose, the research has been pinpointed on the inspection framework, on the inspectors and client roles and, with special emphasis, on the methodologies used for identifying and ranking the safety problems. In order to test the reliability of the methodology, the agreement of the results of the safety issues ranks produced by different inspectors has been addressed. Specifically, the statistic kappa has been used. Results show a statistically significant level of agreement among inspectors for the majority of safety issues, confirming the reliability of this methodology.<p />
