Abstract: Real-time scheduling and signal priority strategies play a critical role in improving the service quality of Bus Rapid Transit (BRT) system. The bus start-stop loss, public passengers’ delay and general social vehicles’ delay are essential factors that should be considered for signal priority control. Based on the optimal control of the the BRT Line 1 of Beijing city (South Axis), the paper proposes an integrated control method with modeling the total delay at intersections. The method is based on the signal priority (early green and green extension) and holding strategy. Because of the proposed method, the bus priority is ensured, and the bus delay and negative impact on the general traffic are reduced. The influences from passenger boarding and alighting processes and other factors on the scheduling system are also reduced to some extent. Several traffic scenarios are also used to verify the effectiveness of the presented method.
