The National Road Network
May 24 @ 1:00 pm - 2:00 pm
The FHWA maintains the Highway Performance Monitoring System (HPMS) to collect state level roadway information. HPMS spatial networks (referred to as ARNOLD) are a critical source for several national applications. Although the networks created from HPMS are extensive, state to state connectivity, complete intersection models, and consistent roadway representation between states would increase their application. Recent attempts to use ARNOLD for natural disaster impact assessment have highlighted the need for these enhancements. With dedicated funding from Congress, the FHWA embarked on a project to enhance ARNOLD. The project, called the National Road Network Pilot or NRNP, will produce a national route file with improved spatial network connectivity across jurisdiction lines, refined data to network relationships and improved spatial accuracy. It is anticipated that these enhancements will lead to improved usability of ARNOLD for applications including travel monitoring, safety analysis, freight modeling and emergency response.
This webinar will discuss the development and current status of the National Road Network. FHWA will also discuss some the challenges faced and lessons learned.
