Generating Strokes from City Road Networks

LUAN Xue-chen,YANG Bi-sheng(State Key Laboratory of Information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,Wuhan 430079;Transportation Research Center,Wuhan University,Wuhan 430079,China)  
When dealing with detailed represented city road networks,the traditional stroke generation method will make some mistakes such as dual road separated and roundabout truncated.In order to generate correct road strokes from city complex road networks,a new method is proposed to generate strokes of road networks for dealing with dual road and road junction patterns.The proposed method firstly recognizes dual roads and complicated junctions based on pattern analysis and a hierarchical cluster algorithm,then finds an optimized stroke pair to keep road strokes connectivity.The road network of Wuhan was selected to test the performance of the proposed method.The experimental results show that the proposed method is capable of generating smooth and continuous strokes conforming to perceptual grouping concept.
