New GIS Resources Coming Soon

Stay tuned for new resources from the FHWA GIS in Transportation program. We are excited to share new content with you in the coming weeks, including a summary and recording of the latest peer exchange scheduled for later this month which focuses on how State Departments of Transportation (DOT) can use GIS to support e911, NG911, and other addressing initiatives to support emergency response with partnering agencies. This peer exchange will feature State DOTs from across the country sharing notable practices, lessons learned, and identifying needs.

This new content and more will be available soon. Subscribe to the FHWA GIS newsletter using the link on the right-hand side of the page now to learn when new information will be available.

Upcoming Webinar on The National Road Network

FHWA will host a webinar on Wednesday, May 24th from 1:00 – 2:00pm ET to discuss FHWA’s National Road Network.

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.

Justin Clark and Thomas Roff from FHWA will present information about the National Road Network.

What We Do

The GIS in Transportation program facilitates the knowledge transfer of GIS skills, best practices, and technical resources among State, regional, and local transportation organizations. This website captures the respective lessons learned and makes them available to all GIS practitioners and transportation professionals.

FHWA HEPGIS Application

The HEPGIS website is an interactive, web-based geographic map server that enables users to navigate, view, and print geospatial maps using only their web browser.

Geospatial Data Collaboration

Geospatial Data Collaboration (GDC) is an FHWA Every Day Counts 2 initiative that encourages transportation agencies to use geospatial tools to share data, increase collaboration, and improve the quality and speed of transportation decision-making.
