These days, autonomous driving has become a popular topic in different fields and showed its unavoidable developing tendency. With the increasing application of autonomous vehicles, a mixed period of autonomous vehicles (AVs) and conventional vehicles (CVs) is inevitable. Therefore, some traffic management was proposed. Exclusive lanes for AVs are a new way to improve the mixed road environment's traffic capacity. However, the effect of exclusive AV lanes was rarely studied. Therefore, the decision-makers could not clearly understand this new policy's impact. Besides, the existing research content did not provide a detailed quantitative analysis of this new policy, which is very important for decision-makers. Thus, this thesis focused on the exclusive AV lanes and proposed the following research question: Under which conditions are exclusive autonomous vehicle lanes societally beneficial?
