ITS Asset Viewer provides insight into asset placements for intelligent transportation systems nationwide
The US Department of Transportation (DOT) earlier this year launched the ITS Asset Viewer—an interactive geospatial viewer of the hardware assets—such as cameras, message signs, traffic controls, radio as so on—that comprise the basis for the intelligent transportation systems currently deployed in the US. The ITS Asset Viewer complements the USDOT’s ITS Deployment Tracking Survey and was developed for the ITS JPO by Oak Ridge National Laboratory.

Conducted 10 times since 1997, the survey measures the extent of ITS deployment within 108 metropolitan areas across the United States. The survey helps guide federal ITS research and program management, inform Congress, and assess the cost and operational impact of ITS at the national scale. However, the survey focuses on the quantity of ITS deployment, not their locations within the metropolitan area.
With the advancement of the use of Geographic Information Systems (GIS) for state asset management, it is now possible to assemble a national database of ITS assets with accurate locations along the Interstate system.
The project team launched an effort to gather GIS data from each state department of transportation and assembled the resulting data from a variety of formats into a cohesive picture of national ITS deployment. The viewer visually presents the GIS data from the states (46 states have responded thus far) regarding key ITS technologies such as cameras, messages signs, ramp meters, speed sensors, and roadway weather information systems. Currently, there are more than 75,000 assets in the database, and it is expected to grow as the remaining states provide information.
The deployment of ITS technology can now be integrated with other geospatial information such as evacuation routes, major commercial truck routes, and interstate corridors.
Other USDOT resources such as the data from the Highway Performance Monitoring System can also be integrated to support various analyses. State agencies will be able to get a picture of how other states have deployed assets to address operational needs, such as along major arterials or around special event venues. The information can also help to correlate ITS deployment with traffic volume or average speed and determine where deployment gaps may exist.
The USDOT expects that the nationwide launch of the viewer will encourage other cities, states, and toll agencies to provide their ITS data for inclusion. There are plans to build new functionality into the ITS Asset Viewer to support reports, data downloads, or access via web services, including mechanisms to allow agencies to update their ITS deployment data easily. The result will be a more comprehensive and detailed map of ITS deployment nationwide.
