Abstract :
The paper presents an analysis of the uncertainties of the measurements for the traffic safety. The measurements are obtained by means of a network of wireless sensors mounted on the guardrail. The considered traffic safety measurements are: (i) vehicle speed, (ii) vehicle proximity to guardrail, and (iii) detection of vehicle impacts on the guardrail. For each measurement type, (i) the description of the measurand, (ii) the measurement method and the adopted sensors, and (iii) the evaluation of measurement uncertainties, are reported.
