DTS Helps State DOTs Meet FHWA ARNOLD Requirements

January 20, 2016

In 2012, FHWA announced that the Highway Performance Monitoring System (HPMS) data collection would be expanded in 2014 to include all public roads required under 23 CFR 460. This requirement was later entitled the “All Roads Network of Linear Referenced Data” or ARNOLD. A very helpful overview of ARNOLD from FHWA can be found here:

Many state DOTs have been challenged by the expanded requirements as they focus on their State-owned system while local entities manage non-State public roadways. FHWA decided to help states build a sustainable all-roads network that meets the ARNOLD requirements through the ARNOLD Pooled Fund Study. FHWA is working with state DOTs through the development of individual work plans designed to meet their specific needs and DTS was selected to assist states through a variety of approaches. Activities may include the planning, development and maintenance of the network geometries and linear referencing systems (LRSs) as well as the development and maintenance of network attributes supporting HPMS, MIRE (the Model Inventory of Roadway Elements) and/or FMIS (the Fiscal Management Information System).

DTS is proud to be working directly with all nine participating states including California, Colorado, Florida, Georgia, Kansas, Minnesota, New Mexico, Pennsylvania and Utah.

The table below provides a brief listing of key project tasks and current status for each state.
