Abstract

Cooperative Adaptive Cruise Control (CACC) has gained great attention for its promising capability that dramatically improves the mobility performance of freeway. Numerous relevant research efforts dealing with CACC have been performed but almost all such efforts mainly focused on the development of CACC logic and validation in its mechanical aspects. This paper assesses the potential mobility benefits of CACC under the wide range of plausible traffic congestions conditions with two CACC headway times (i.e., 0.6 and 0.9 seconds) and five CACC market penetration rate cases (i.e., 5%, 10%, 20%, and 30%) which are expected to reach in a near future. A VISSIM-based simulation study showed that CACC saves total travel time up to 16.3% and improves the average speed of the entire network by 15.7% at the 30% of market penetration rate, while the improvement of system throughput appeared insignificant.
