Connected vehicles are those that communicate with neighbouring vehicles (V2V) and nearby infrastructure (V2I). Automated vehicles are those that are partially or completely controlled by computers with less or no intervention from human drivers. Recent developments of V2V, V2I, and vehicle automation technologies have enabled the concept of the connected and automated vehicles (CAVs) to be tested and explored in practice. It is predicted that very soon CAVs will share transport infrastructure with conventional vehicles, which may fundamentally revolutionize our transport systems. With coordination, cooperation, and automation, many believe that CAVs hold the potential to improve transport safety, efficiency, and sustainability. However, detailed modelling and technical paths for our existing transport systems to fully capitalize on the CAV concept are yet to be explored, investigated, and examined. It is urgent now to develop innovative ideas of utilizing CAVs technologies to improve our transport systems from various aspects, scales, and dimensions. This special issue is focused on the recent advances in modelling connected and automated vehicles. Applications of CAVs eliminate or alleviate traffic bottlenecks and increase traffic capacity

Potential topics include but are not limited to the following:

• The use of CAVs to improve traffic safety and sustainability (e.g., less fuel consumption and emissions)
• Applications of CAVs to harmonize traffic flow
• Applications of CAVs in vehicle routing problems
• Characteristics of mixed traffic flow combining conventional, connected, and automated vehicles
• CAVs and macroscopic traffic flow models
• CAVs and dynamic and static network modelling
• CAVs and traffic signal control
• CAVs and human behaviour
• CAVs and scheduling
• CAVs and multimodality
• Innovations on CAV testbeds
• Applications of CAV in shared mobility
• Applications of CAV in logistics and supply chain
