Estimated capital costs to equip 10 intersections with DSRC radio communications and backhaul needed to support V2I applications can range from $443,000 to $644,000.

Case Study on connected and automated vehicle technologies.


Summary Information

To illustrate the type of connected and automated vehicle technologies and projects that States may incorporate into their Clear Air Act State Implementation Plan (SIP) this study assessed the benefits and costs of an Eco-Arrival and Departure at Signalized Intersections (EADSI) application. EADSI uses Vehicle-to-Infrastructure (V2I) communications, Signal Phase and Timing (SPaT) information, and geographic information to determine the most fuel efficient speed at which a vehicle can either pass through the next green signal, or decelerate to a stop.

The table below excerpted from the source report presents a high-level estimate of the capital costs to deploy connected and automated vehicle infrastructure, equipment, and EADSI applications. The example depicts installation of Dedicated Short-Range Communications (DSRC) Roadside Units (RSU) at 10 intersections with 20 aftermarket On-Board Units (OBU) installed on 20 agency vehicles. Each intersection would require a signal controller and backhaul upgrade.
