About ITS Standards

ITS Standards and the U.S. DOT ITS Research Initiatives

The U.S. Department of Transportation's (USDOT) Intelligent Transportation Systems (ITS) program is launching a new generation of research initiatives aimed at bringing ITS to bear on real-life transportation problems by improving transportation safety, relieving congestion, and enhancing productivity. ITS standards play an important role in achieving these objectives.

Connected Vehicle Standards

The development of connected vehicle system standards is an effort that is informed by:

Short Term Intermodal Research

  • Active Transportation Demand Management
  • Commercial Vehicle Information Systems and Networks (CVISN) Core and Expanded Deployment Program
  • Intelligent and Efficient Border Crossings

Standards are planned but not yet developed for Short Term Intermodal Research applications.

Standards Associated with Earlier Research Programs

Past ITS research programs are bringing ITS to bear on real-life transportation problems by improving transportation safety, relieving congestion, and enhancing productivity. ITS standards play an important role in achieving these objectives. The USDOT Joint Programs Office has mapped standards to four past major research initiatives:

Only a subset of the entire list of profiles is needed when deploying, and it is based on the type of communications system being used. Potential profiles needed for the ITS standards in Tier One ETO are:
    • Profiles when using wireless communications
    • Profiles for Ethernet/internet
    • Profiles for dedicated phone lines
    • Profiles for generic telephone lines
