Automated vehicles can have useful applications in the airport airside environment, bringing potential benefits such as improved traffic safety, efficiency and reliability. But these potential benefits are fully realized only when automated vehicles form the majority of airside road traffic. During the transition phase, airport operators are facing challenges in ensuring traffic efficiency and safety when assimilating automated vehicles into the existing human-driven vehicular traffic. The crux of these challenges is the lack of information synchronization and movement coordination between automated vehicles and human-driven vehicles. Two sets of traffic protocol are proposed in this paper to allow the feasible operation of mixed-mode airside road traffic. Both sets of protocol adopt the central control and space-time reservation features of a semi-autonomous intersection management (semiAIM) model, as well as take into account the airside road traffic conditions and ground handling operational requirements. The first set is the dynamic stopping semiAIM protocol which is more suitable for when automated vehicles form a small proportion of vehicular traffic. The second set is the pre-mapping semiAIM protocol which is more suitable for when the automated vehicle population grows to a larger proportion. Through two airside traffic scenarios, it is demonstrated that the proposed protocols can improve efficiency of mixed-mode airside road traffic without compromise in safety. To translate the proposed sets of protocol into a ready-to-implement solution, a three-step framework is set up for the next phase of works: an analytical desk study, computer simulation study and in-situ trials.
