This paper proposes a two-direction green wave control algorithm of traffic signal based on particle swarm optimization. The traffic flow model of queuing length and two-direction green wave control object function were built. The signal split and the phase offset were optimized by particle swarm optimization. The simulation result with traffic data collected from Liansheng Road in Dongguan City proved this method was effective and practical. Compared with graphical method and actuate signal control, the proposed algorithm could effectively reduce delaying time and shorten queuing length.

The smart teaching mode overcomes the shortcomings of traditional teaching online and offline, but there are certain deficiencies in the real-time feature extraction of teachers and students. In view of this, this study uses the particle swarm image recognition and deep learning technology to process the intelligent classroom video teaching image and extracts the classroom task features in real time and sends them to the teacher. In order to overcome the shortcomings of the premature convergence of the standard particle swarm optimization algorithm, an improved strategy for multiple particle swarm optimization algorithms is proposed. In order to improve the premature problem in the search performance algorithm of PSO algorithm, this paper combines the algorithm with the useful attributes of other algorithms to improve the particle diversity in the algorithm, enhance the global search ability of the particle, and achieve effective feature extraction. The research indicates that the method proposed in this paper has certain practical effects and can provide theoretical reference for subsequent related research.
