A New Traffic-signal Control for Large Multi-branch Roundabouts

摘要：

As time goes by, the heavy traffic exceeds the capacity of most unsignalized roundabouts, especially Large Multi-branch Roundabouts (LMR). In this paper, we propose an innovative control model of LMR based on accurate traffic perception. We present a concept of Optimal Number of Vehicles within the Roundabout (ONVR) and find that the LMR can get a higher realtime capacity if the Current Number of Vehicles within the Roundabout is kept on the ONVR level. At last, we apply a simulation experiment to Zhongshan Square in Dalian, China. The result shows that the real-time capacity of Zhongshan square is raised by about 40％ and the vehicle travel time is reduced by 30％ on average during the rush hour.
