Findings:
•CACC
simulations achieved significant reduction in travel delays and improvement in flow
•Drivers
of the CACC system selected vehicle-following
gaps that were half the length of the gaps they selected when driving the ACC system
•This
result has favorable implications for adoption and use of CACC to improve highway capacity and traffic
flow
Experiment
highlights:
•Experiment
tested 16 naïve drivers’ performance and choice-making in ACC and CACC
environments
•Subjects
adjusted following time gap settings according to preference in different
traffic conditions
