System-Wide Impacts of Arterial and Freeway Eco-Cooperative Adaptive Cruise Control

Eco-cruise control systems compute vehicle speeds with the goal of minimizing fuel consumption and emissions. Previous research studied the effects of applying eco-cruise controls on either freeways or arterial roads. The tested network was small in scale with either a short spatial span or a small number of roads. The goal of this study was to compare the impacts of Eco-Cooperative Adaptive Cruise Control (Eco-CACC) methods when they are applied on arterial roads (Eco-CACC-A), on freeways (Eco-CACC-F), and on both (Eco-CACC-F+A) across an entire network. The effectiveness of Eco-CACC methods is evaluated in terms of average delay, fuel consumption, and emissions (HC, CO, NOₓ and CO₂). Using a microscopic simulation tool, INTEGRATION, three sets of input parameters — speed limits, traffic demands, and market penetration rates — are tested in this study to quantify the impact of these parameters on the performance of Eco-CACC systems. A total of ten random seeds were applied for a total of 760 simulation runs. All results were compared to a base case in which no Eco-CACC strategies were applied. The results show that, compared to Eco-CACC-F and Eco-CACC-F+A, Eco-CACC-A leads to fewer delays. In terms of fuel efficiency, the effectiveness of Eco-CACC-A is less significant than the other two control methods. Eco-CACC-F and Eco-CACC-F+A produce improvements in fuel consumption and emissions with the increase of freeway speed limits and market penetration rates. Though the improvement of fuel efficiency decreases with a higher demand, the benefits from Eco-CACC-F and Eco-CACC-F+A are consistently more obvious than Eco-CACC-A.
