Abstract:The landside road of large hub airport has the characteristics of large scale, complex traffic organization and large traffic flow. The traffic facilities are the important part of the airport. The reasonable and scientific design of traffic facilities is the prerequisite for efficient operation of road system. The classification of airport road traffic facilities is systematically cleared. Based on the specific engineering cases, the overall guidelines for the design of airport road traffic facilities are summarized, and the core design essentials of intelligent guidance, elevated road traffic sign, ground road traffic sign and tunnel traffic sign are refined and expounded, which can provide the useful references for the design of road traffic facilities in large hub airport.
