Prioritization of Information Interaction Types in Cooperative Vehicle-Infrastructure Systems on Highways Based on Analytic Network Process

Cooperative Vehicle-Infrastructure Systems (CVIS) are an important subsystem of intelligent transportation systems. This paper sorted out typical scenarios in CVIS, then used analytic network process (ANP) to build the network structure model for the different scenarios. An information interaction priority hierarchy model was established, which fully considered the relationship among factors and the objective information contained in the factors themselves, and determined the priority of the information interaction. This paper divided 4 typical scenarios for CVIS on highways, and each scenario corresponded to a series of services. The priority of different services was determined through the information interaction priority hierarchy model, and the ranking results were analyzed from intragroup and global perspectives. Results show that the priority of information interaction in the traffic safety and control scenario is significantly higher than in other scenarios, and there is an obvious order of priority for different information interactions in the same scenario.
