Functional Analysis of a New Concept of WIM Sensor by Using Failure Mode and Effects Analysis (F.M.E.A.)

The overloading vehicle become an important problem for Europe Union, protecting the environment and increase the traffic safety. WIM or weigh-in-motion systems can monitor the traffic, determine the volume and type of traffic and detect the overload vehicles which are illegal. This paper discusses about applying the Failure Mode and Effect Analysis method for developing a new concept of WIM sensor, designed in PhD thesis from “Gheorghe Asachi” Technical University of Iaşi. FMEA method or also called potential failure modes and effects analysis is a step-by-step approach for determine and identifying all possible failures in a new design, or manufacture process. This new concept of sensor can be used for urban traffic in order to reduce the cars pollution in the cities by providing real-time data traffic, monitoring vehicles and detecting the overloaded trucks. The FMEA method was applied for identification of functional failure risks and preventing failures from an early stage of concept.
