The Roadway Data Office is responsible for the management of the statewide Linear Referencing System (LRS). The office is responsible for the maintenance of over 95,000 miles of public roadway data, municipal boundaries, and also the collection of roadway characteristics. The data collection and maintenance activities performed by the Roadway Data Office supports the TRIMS and E-TRIMS application which allows users to accurately visualize roadway data and produce relevant datasets for ongoing projects and studies.

The Roadway Data Office also conducts specific research with the goal of improving the efficiency of our data collection methods, data structure and storage, and data maintenance. Other tasks and research performed by the Roadway Data office include Weigh-In-Motion, local roadway data integration, state aid processes, and compilation of a digital map archive.
