Case Study on connected and automated vehicle technologies.
262
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 |
