| Abstract: | Widening approach is an efficient measure to improve running condition and increase capacity of intersections.However,there are few analyses on traffic flow of widened intersection.The paper analyzes flow rate of widened intersection.A uniform delay calculation formula of widened intersection is presented through analyzing the cumulative arrival-departure diagram.A modification is conducted to classical overflow delay and the average delay model of widened intersection is put forward. |

| Keywords: | widened intersection uniform delay overflow delay average delay |
