The connecticut department of transportation utilizes laser videodisc technology to store millions of frames of roadway images. The photolog laser videodisc (plv) system is a menu-driven pc-based workstation that is used to access images of any active state route. To maximize usage of the plv hardware, the department is actively developing other applications. This report addresses the development of ademonstration bridge information system (bis) that makes use of thecurrent plv image-retrieval concept in conjunction with a relational database. The system was designed for storage and quick retrieval of both alphanumeric data and images concerning bridges. The alphanumeric data are divided into four general areas on a bridge-by-bridgebasis. Three areas contain static information such as structural dimensions, construction-project details, and on-site utility information. The fourth area chronologically lists events concerning a bridge, such as an inspection, rehabilitation, or maintenance activity. Captioned and dated images of the bridge selected in the alphanumericdata areas are accessible as a menu selection. A hard-copy output of both the alphanumeric data and images are also available. This paper appears in transportation research record no. 1290, Third bridge engineering conference, march 10-13, 1991, denver, colorado, volume 2.
