Abstract: This paper proposes to set up the variable message signs (VMS) in the airport to provide information such as queuing time, road congestion and transit service levels, so as to guide passengers to make the best choice of traffic mode on the basis of the original decision. Considering the order of obtaining travel information, the decision-making process can be divided into two stages. In the first stage, passengers select the travel mode depends on the individual experiences or mobile navigation information. In the second stage, the VMS information would affect the passengers' selections. The passenger mode transfer model based on the Nested Logit model is established, and the information data of the two stages are fused by the full probability formula to obtain the passenger' traffic mode selections. The effectiveness of the model is verified through numerical simulations. The results show that the high quality and combination of waiting time information, road congestion information and transit service information is beneficial to improve the utilization rate of public transport and system operation efficiency, which can increase the utilization rate of public transport by 3% and reduce the system operation time by 13.8%. The more congested the road condition is, the more important the road information to the passenger's traffic mode selections. When the traffic demand is light, providing VMS information can still improve the utilization rate of airport buses.
