The Intelligent Transportation System (ITS) program is an initiative of the United States Department of Transportation to add information technology to transport infrastructure and vehicles. It aims to manage vehicles, loads, and routes to improve safety and reduce vehicle wear, transportation times and fuel costs.
The ITS program was originally called Intelligent Vehicle/Highway Systems.
Intelligent Transportation Systems are a set of related technologies, including:
- archived data
- archived data mart
- archived data warehouse
- archived data virtual warehouse
- advanced public transit systems
- transit vehicle tracking
- transit fixed-route operations
- demand responsive transit
