The invention discloses an urban traffic signal control system and method based on a scheme knowledge base, and the system comprises an expert scheme base, an iteration scheme base, a scheme input module, a scheme judgment module, a label obtaining module, a mode matching module, a scheme generation module, an effect evaluation module, a scheme updating module, and a scheme execution module. S1, obtaining a scene label based on a real-time traffic mode scene; s2, matching an expert scheme library and an iteration scheme library based on a scene label sequence, and outputting a control scheme with an optimal scoring result; s3, judging a scheme to be issued; s4, issuing the control scheme to a signal platform; s5, the issued control scheme is scored; and S6, updating an expert scheme library control scheme and an iteration scheme library control scheme according to the scheme scores. The method has the beneficial effects that the control schemes with good application effects can be used as experience accumulation to form a scheme knowledge base, and when the same traffic scene appears again, the control schemes with good regulation and control effects are quickly matched to realize scheme reuse.
