An effective and widely-applied redesign for traffic circle

In this paper, we propose an effective redesign for traffic circle for the sake of extensive use. Three evaluation indexes are used to classify the category of district where a traffic circle belongs to. With the help of the most essential evaluation index, through calculating from two differently improved methods which are distinguished by whether use traffic lights or not, an optimal proposal can be obtained after comparing the outcomes. In addition, correspondingly implemental arrangements can be set up for concrete traffic construction. Our experimental results show that the achievement of this redesign is significantly widely-applied.
