英文摘要：

Maintai task for in-vehicle commonly conduc intrinsic rules of t ning the traffic connectivity relations between road features has always been a time consuming navigation, mapwebsite, and other traveling service related applications. Sucha task has been ted artificially and inevitably inefficient, yet makes data quality control difficult. Considering the raffic connectivity formed by the geometrical structures, spatial and semantic relationships be- tween road features in city road networks, an intelligent processing model is set forward in this paper for traffic connectivity automation. It is argued that traffic connectivity automation between rood features is fundamentallya production system composed of the spatial and semantic relations between road features, connectivity rules and control system. With the implementation of an extendable connectivity rule set, the traffic connectivity relations between road network features are built automatically based on the spatial and semantic information of road network. The trigger concept is adopted to monitor and respond the changes in geometrical network and connectivity rules, and then dynamically updates the traffic connectivity between road network features in logical network so as to guarantee the consistence between geometrical network, connectivity rules and logical network. A series of control strategies and a conducting engine are developed to maintain the traffic connectivity relations. A case study conducted on a real road network verifies the effects of the proposed intelligent model.
