Field Testing of Eco-Speed Control Using V2I Communication
The project entitled “Eco-speed control using V2I communication” sponsored by the AERIS program under FHWA’s Research and Innovative Technology Administration and (RITA) and the “Eco-Cooperative Adaptive Cruise Control” project laid ample foundation on the feasibility of reducing vehicle fuel consumption levels in the vicinity of signalized intersections when Signal Phasing and Timing (SPaT) information is communicated to approaching vehicles. Informed drivers/vehicles can alter their speed in the vicinity of intersections to minimize idling and in many cases, loss of inertia. Two approaches to this logic were studied using agent-based simulations in MATLAB: (a) Eco-speed control in which an in-vehicle device receives SPaT information, does the calculations and provides instantaneous speed advisories to drivers which, if followed accurately, can benefit the driver by lowering the vehicle fuel consumption and (b) Eco-Cooperative Adaptive Cruise Control (ECACC) which uses SPaT information, lead/queued vehicle information and automatically controls the vehicle speed to achieve the “advised fuel-optimum velocity trajectory”. Fuel consumption reductions of up to 23 percent were found based on simulation studies of a single vehicle.

However these simulations make some simplifying assumptions that may not be realistic, where either the driver perfectly follows the speed advisory or the ECACC is 100 percent accurate. This is in addition to the neglected uncertainties regarding the DSRC communication and any communication latencies. Field tests are sought for further analysis and research regarding Eco-Speed Control and the Connected-vehicle test bed of the New River Valley and potentially Northern Virginia is deemed to be an ideal candidate for this effort.
