Intelligent transportation systems (ITS) infrastructure impacts on operations and maintenance are on several levels, including the maintenance and operation demand, staffing required, and the cost to ensure the new systems continue to operate. Traffic engineering staff are being asked to do more than ever as fiber communications, cameras, sensors, and cellular vehicle-to-everything (C-V2X) are being deployed. Even traditional maintenance has taken on an increased urgency when sensors’ operational uptime is being pushed to 100%. New skills and expertise are needed to maintain and operate new communications, networks, and audio-visual assets. Traditional traffic engineering tasks like signal timing are more complex. Budgeting considerations to keep up with the new systems and ensuring the latest technologies can be accommodated are being challenged as well. Jurisdictions should focus on the operation and maintenance of both new and legacy systems to ensure efficient and cost-effective results for the public.
