As a first step for the safety network integration, test bed bridge was integrated by using the FBG sensor system. For the operating efficiency of the bridge monitoring system, software which can control the conventional sensor system and fiber optic sensor system concurrently was developed. Measuring item was limited to the strain, and the other measuring items such as acceleration or displacement will be applied to the bridge next research period. Beside these items, image processing device was installed to the test bed bridge, and the applicability of these data was considered. As a result of strain measurement, the data from fiber optic sensor system were high stable and reliability, and the problems or advanced parts will be suggested during the test bed bridge operation in the future.
