This paper describes a possible design of encapsulation of fiber Bragg grating (FBG) for the traffic applications. We have simulated properties and then created two type of encapsulation of FBG into polymer polydimethylsiloxane (PDMS) and lukopren (carbohydrate binder). Encapsulated FBGs were stored in the created concrete road retarders. These retarders were burdened by the repeating passes of the testing vehicles (10 different vehicles). We analyzed the detection capability of vehicles, compared obtained results and discussed the influence of above-mentioned encapsulation on the FBGs (in case of uses for traffic applications).
