During the design and administration of expressway traffic signs, people always treat one single sign, instead of thinking about the relationships of signs on an entire network composed of different expressways. In fact, traffic signs, especially the guide signs, act as a system, which seems to have great logic. Their locations, types and information on the panels are reasonable and correlative. The paper designs the topology model of the expressway network, with the consideration of exits, entrances, interchanges and nodes of expressways, makes a logical definition of the guide signs, and discusses the relationship between the guide signs' logical definition and expressway network topology. With the logical definition, there are a lot of applications, such as automatically choosing as well as altering the guide signs that are related to the added expressway or the dropped one, and altering the relative guide signs with the adjustments of the topology of the expressway network during the expressway rebuilding and traffic administration.
