Connected Vehicle System Deployment Costs are Estimated at $3,000 to $5,000 per Roadside Unit and $2,000 to $3,000 per Onboard Unit with Existing System Upgrade Costs Estimated at More Than $20,000 per Location.

Deploying Connected Vehicle (CV) technology requires new roadside and vehicle equipment as well as upgrades to existing infrastructure. A phased rollout that begins with assessing current assets can help reduce costs by leveraging what is already in place. Successful deployment will also require investments in communications bandwidth, data management, traffic signal systems, and roadway markings. Drawing on lessons from peer deployments such as the I-24 Smart Corridor Testbed and the UT Chattanooga MLK Smart City Corridor, TDOT has developed cost estimates for implementing CV technologies.

CV System Deployment Cost Estimates:

• Roadside Unit (RSU) hardware and integration: $3,000-5,000 per device
• Onboard Unit (OBU) hardware and integration: $2,000-$3,000 per device
• Security Credentials Management System (SCMS) (RSU certificates): $30-$40/month/RSU
• SCMS (OBU certificates): $10/month/OBU
• Management System: $50-200/month/RSU
  • Varies based on functionality, vendor support provided

Note: Costs exclude additional development and testing. Economies of scale may reduce unit costs as deployments expand.

Existing System Upgrade Cost Estimates (if needed):

• Backhaul communications (fiber): $20,000+ per location
  • Depends on distance between locations
• Backhaul communications (cellular): $1,000-$1,500 per location + monthly data
• Traffic Signal Controller (new): $4,000-$5,000
