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.

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.

Item Quantity Per Unit Cost Total Costs
Dedicated short-range communications roadside units 10 intersections $13,100 to $21,200 $131,000 to $212,000
Signal controller upgrade 10 intersections $3,200 $32,000
Backhaul communications 1 system (10 intersections) $30,000 to $40,000 $300,000 to $400,000
Light vehicle aftermarket on-board unit with graphic interface 20 vehicles $10,000 $200,000
Connected/Automated Vehicles Project Total     $663,000 to $844,000
