Using Semantic Techology for Consistency Checking of Road Signs

With the cities ever growing and evolving much faster than before, effectively managing road signs is a major problem, in particular checking the positioning and contents of road signs in compliance with related road sign regulations (RSRs) and validating if the newly built road signs are consistent with existing road signs according to RSRs. In this paper, we discuss challenges in developing road sign management system and propose a data integration solution which provides a basis for intelligent road sign management based upon the LarKC platform. We then present methods for automatically verifying road signs according to RSRs and simulating the process of generating new road signs when new roads are to be built. The proposed system can bring much convinence to decision makers and greatly decrease fees of the city operation.
