A large percentage of drivers like listening to music, radio, or talking to passengers while driving, especially phoning in recent days, even if they use bluetooth earphones or car phone instead of holding the phones by hand. However, such extra cognitive workload will have an impact on drivers’ driving performance. In this study, a driving simulator based experiment was designed to find out drivers’ performance under smooth car-following drive and critical situations. In this experiment, 24 participants (male = 13, female = 11) were required to drive the same city road route twice, with and without extra cognitive workload. Driving performance is measured in driving safety and stability with several indicators. While smooth following the lead vehicle, drivers’ operations are probably not change, however, their risk perception have been increased. Once critical situations happen, extra workload put drivers into a more dangerous and higher risk to collision circumstances. Most of the stability metrics show significant difference between drives with and without extra workload. It is hypothesized that extra workload makes drivers distracted so that they need to adjust velocity and position more frequently.
