| Abstract: | In order to improve the prediction pricesion of the short-term traffic flow of road cross section, by chaotic time series analysis and the phase space reconstruction of the multi-dimensional short-term traffic flow data, a short-term traffic flow forecast model of road cross section based on chaotic time series analysis was put forward. The parameters of the forecast model was optimized with the particle swarm optimization algorithm. Meanwhile, the forecast model proposed in the paper were tested by the rea... |
