This document provides practical guidance and a handy Reference Manual to assist state DOTs in moving forward to meet the new Highway Performance Monitoring System (HPMS) requirements for the submittal of complete, all roads inventories and linear-referenced networks for every state and territory. This requirement is known as ARNOLD – the All Road Network of Linear Referenced Data. ARNOLD replaces the previous requirement of only collecting Federally Aided Route networks from each State. The ARNOLD Reference Manual covers the four overarching steps for a statewide, all-roads linear referencing system (LRS) implementation process including implementation planning, data collection and integration, building the LRS, ongoing data maintenance. The main body of this document is synoptic and is aimed at walking a user through the overall process of planning and developing a statewide, all roads network that includes LRS. 1
