چکیده

Traffic flow is chaotic due to nonstationary realistic factors, and revealing the internal nonlinear dynamics of data making high-accuracy predictions key traffic control inducement. Given that high-quality phase space reconstruction foundation predictive modeling. Firstly, an improved C-C method based on fused norm search domain proposed address issue in algorithm does not meet Euclidean metric accuracy reduces quality when infinite used. Secondly, problem insufficient learning ability traditional convolutional combinatorial modeling for complex laws flow, high-dimensional features are extracted using layer-by-layer pretraining mechanism deep belief networks (CDBNs), temporal by combining with long short-term memory (LSTM). Finally, probabilistic dynamic reproduction-based genetic (PDRGA) hybrid model falling into a local optimum law. Experiments conducted three aspects: analysis, comparison optimization convergence, prediction performance comparison. The experimentation two sets demonstrates combines advantages high L2 low operational complexity norm, achieving balance between efficiency. PDRGA lightweight improvement (GA) solves tends fall optimizing initial weights CDBN. Meanwhile, five error evaluation indexes PDRGA-CDBN-LSTM lower than those baseline model, providing new idea prediction.
