Travel time reliability (TTR) is an important measure to evaluate the performance of transportation networks. With their access to timely and accurate travel time information, Connected and Autonomous Vehicles (CAVs) promise to bring significant improvements in TTR of a road network. TTR of a transportation road network under various disruptive events taking place in a mixed traffic environment consisting of different CAV penetration rates. The TTR levels (i.e. the probability that the travel time on a given path is shorter than a given threshold) and the failure probability of travel time (i.e. the probability that the travel time on a given path is greater than a given threshold) is calculated for the situation where the total travel time threshold is 35 min. Results show that higher penetration rates of CAVs have the potential to improve reliability. In addition, analyses show that the TTR decreases immediately after disruption occurrence due to the failure of some nodes and links in the network. However, increasing the CAVs penetration rate is shown to decrease the reduction of TTR significantly after the disruption phase.
