Cost

System costs for roadside traveler information systems were projected for upstate California; installation of changeable message signs (CMS) and mounting structures were estimated at $140K to $300K per site.

Summary Information

This research identified strategies to integrate ITS applications into the California Regional ITS Plan over the next ten years. Estimates of initial capital costs and ongoing annual operations and maintenance costs were derived from an analysis of data in the national ITS costs databases and input from Caltrans staff.

System costs for particular ITS applications can vary greatly depending on the availability of existing power connections and communication links to transportation management centers (TMCs). Estimates presented in the descriptions below exclude the costs for power connections and backhaul communications links.

ITS Functional Element: Traveler Information Management.
  • Changeable Message Signs (CMSs). Advanced Signal Operation and Infrastructure. CMSs (also referred to as dynamic message signs or DMS) are large electronic signs that can post a range of standard and customized messages. They can be used to provide messages about roadway status (e.g., open, closed, construction, weather, incident, alternate routes) and, in certain circumstances, provide advice to drivers. CMSs are configured and controlled by a TMC.
    • Capital Cost:
      • $40,000 to $100,000 - per sign
      • $100,000 to $200,000 – mounting structure

      Power and communication costs can vary significantly and are dependent on location. Additional costs may include maintenance pullout and guardrail.
    • O&M Cost:
      • $5,000 per year. Additional cost if communication is leased
  • Highway Advisory Radio (HAR). HAR is limited range radio that includes beacon and radio transmitter and typically a sign to inform approaching drivers that a message is being broadcast. Can allow for a more detailed or extended message than possible with a sign; good for scheduled activities (e.g., construction, major events) where it can forewarn travelers about upcoming conditions and schedule).
    • Capital Cost:
      • $125,000 – transmitter/tower
      • $50,000 - HAR flasher

      Power and communication costs can vary significantly and are dependent on location. Additional costs may include maintenance pullout and guardrail.
    • O&M Cost:
      • $600 - $1,000 per year
