Cooperative vehicle-highway systems coordinate vehicle communications and remote traffic microwave sensors to increase overall system performance and sustainability. One strategy of cooperative vehicle-highway systems is speed harmonization, which dynamically adjusts vehicle speed recommendations in order to reduce speed differentials. This report describes a preliminary experiment of vehicle-to-infrastructure-based speed harmonization in which speed guidance is communicated directly to vehicles. This report reviews a set of micro-simulation experiments and a limited number of prototype field runs, including site selection, setup, and analysis. This report will be of interest to researchers concerned with implementation and utility of early cooperative vehicle-highway system deployments.
