A Federal report highlights best practices for ITS programs that plan to implement connected vehicle (CV) technology.

Guidance for short-, medium-, and long-term transportation planning efforts.

Nationwide; United States

Background (Show)

Lesson Learned

The following are several recommendations presented in the report that highlight the range of issues agencies need to consider within short-, medium-, and long-term transportation planning efforts:

For near-term:
  • Develop and maintain a Concept of Operations (ConOps) that baselines the characteristics of the proposed system and identifies the roles, features, functions, and communications needed.
  • Explore partnerships with neighboring and overlapping agencies/jurisdictions to support seamless interoperability.
  • Engage a wider variety of stakeholders including vehicle and telematics manufacturers as well as cybersecurity firms.
  • Plan for increased data quantities and third party support in areas of data security.
  • Identify any existing regulatory and/or legal hurdles to CV investment and testing.
For medium-term:
  • Work with signal control vendors to develop upgrades necessary to support CV interfaces and Signal Phase and Timing (SPaT) messaging and data collection.
  • Plan for strict security policies and procedures for all systems and users of the CV systems and networks.
  • Develop data monitoring and feedback mechanisms to observe and understand the impacts existing CV deployments have on performance and operations.
  • Maintain outreach with advisory panels and study groups, and participate in conferences to keep up to date with industry developments relevant to operations and planning.
  • Use the ConOps to help manage operations and define thresholds for phasing out obsolete technology, and determine how roles and responsibilities may change among agency staff and contractors.
  • Educate the public on opportunities to use CV systems with in vehicle systems and participate in developing programs.
For long-term:
  • Develop a communications master plan to support their traffic control systems and CV backhaul.
  • Expect technology refresh efforts. CV technology is likely to require large scale upgrades or even equipment replacement as the communications technology evolves.
  • Expect Roadside Unit (RSU) infrastructure to require significant O&M.
