Across the country, DOTs (departments of transportation) are becoming more tech savvy, implementing the latest technologies and tools such as geographic-information systems and advanced infrastructure technology, among others.

One recent example comes from the Hawaii Dept. of Transportation,, Honolulu, Hawaii. The Hawaii DOT has been on the leading edge of technology implementation, employing a portal with integration of relational database-management systems, geographic-information systems, Internet mapping, and global-positioning systems.

Last week, the Hawaii DOT announced it is using a MLRS (multilevel linear referencing system) to improve the process of maintaining the department’s digital highway network data. Overall, the technology will help the Hawaii DOT plan, design, construct, and maintain operations of highways more effectively.

The technology provides the ability for a DOT to analyze road networks. MLRS is an automated approach to managing components in a linear reference system network. It can represent multiple linear referencing methods such as county-route-logmile, street name-address, intersection-offset, and can be displayed on a map using multiple geometric representations.

This technology simplifies network maintenance for a DOT. Intergraph,, Madison, Ala., provides a core data model and software that manages the parts of the LRS independently through a database.

With the Intergraph MLRS data model, the Hawaii DOT can manage the data representing the LRS network to geospatially locate roadway information for analysis and transform event data between referencing methods, saving time and avoiding costly data conversion errors.

According to Goro Sulijoadikusumo, planning survey section manager, HDOT, the transportation software from Intergraph is integrated with the Highways GIS Portal, and the roadway-information system is integrated with the traffic-monitoring system. This results in less duplication in data entry.

The technology is here and DOTs are taking advantage of the solutions that are available. It will be interesting to see how technology will continue to be leveraged on infrastructure construction projects in the years to come.
