For more than 20 years TINIS, the Maine Department of Transportation’s (MDOT) integrated highway information system, has provided a means of locating assets and projects. However, it has not been easy to integrate TINIS ( a mainframe legacy system) with modern relational databases or Geographic Information Systems (GIS). To address these deficiencies, MDOT chose to buy a commercial off-the-shelf (COTS) software package called Highways by Exor.
The Network Manager and Spatial Data Manager modules of Highways by Exor were implemented in June as part of the METRANS project. The new system provides both a linear referencing and a spatial network hub, which enables MDOT to synchronize location referencing data in Highways by Exor with other departmental systems.
Initially Highways by Exor was acquired as a linear referencing management system to enable MDOT’s Systems Management Division (SMD) to maintain a database of 22,669 miles of public roads throughout Maine. In late 2003, SMD started using Highways by Exor to manage and query their highway inventory database, which consists of 71,141 anchor section records and 29,073 routes on 6 route systems. The system's multiple linear referencing capability enables users to use any of the route systems to query asset records. Since network and asset geography is integrated into the Highways by Exor database, each record is edited once, and Highways by Exor keeps spatial, linear referencing, and attribute information synchronized. In the future, MDOT anticipates that its project tracking system and the systems that manage accidents, bridges, and pavement data will also be synchronized with the up-to-date network location information in Highways by Exor.
