An Improved Actuated Signal Control of Intersection Based on VISVAP

Traffic congestion has become an inevitable problem in modern society, and the signal control of intersection plays an important role to ensure the effective operation of urban transport.The paper proposes an improved actuated signal control model to improve the running efficiency of intersection.In order to verify the effectiveness of the improved algorithm，the paper uses VISSIM to simulate the operating condition of different durations under timing control, actuated signal control and improved actuated signal control based on actual traffic flow, signal timing and other data of intersection.The simulation result shows that travel time and delay time are both reduced under the control of actuated signal in different time periods.And the improved actuated signal control is more effective than other signal controls.
