ve the problem of congestion at the intersection the two－phase signal control intersection is used as the research object and the
vehicle queuing length model in different states is established． The deviation between the measured value of the length and the
expected value establishes the corresponding feedback control rule． We use Matlab to access the Vissim － COM interface to
，
dynamically access and manipulate Vissim objects change the unit time throughput and queue length of the intersection by adjusting
，
the signal cycle duration and then perform simulations under different traffic conditions to analyze and optimize the traffic of the
intersection before and after performance and operating status． Experiments show that the established signal feedback control model
can better adapt to the dynamic changes of traffic flow and improve the operation efficiency of intersections．
