This paper describes test and evaluation methodology as well as preliminary results from the Intelligent Cruise Control (ICC) Field Operational Test (FOT) that is being conducted in Southeastern Michigan. The ICC system is first briefly described. The evaluation goals are then briefly delineated. Focus is placed on safety benefits to users and impacts on the transportation system. The evaluation framework considered driving states and basic safety factors such as headway following and driver attentiveness. Preliminary results are expressed in terms of driving safety, traffic flow impacts, environmental impacts, and the influence of ICC on the driving task. No indications of significant safety impacts were found in the preliminary analysis as measured by the frequency of exceeding safety boundaries. However, with less short headway distances, ICC driving is potentially less stressful as well as potentially safer than manual driving.
