Abstract

Abstract: There is a complex nonlinear relationship between highway traffic flow and its influencing factors.Combing least squares support vector machines(LSSVM)with adaptive dynamic particle swarm- optimization(ADPSO)algorithm,this paper proposed a new highway traffic flow forecasting method based on LSSVM optimized by ADPSO algorithm.Highway traffic flow was forecasted by LSSVM with the advantages of easy modeling and high precision.And the optimal parameters of LSSVM were selected based on the good optimization ability of ADPSO algorithm.An example analysis on the highway traffic flow in a city was performed to test the effectiveness of LSSVM-ADPSO model.The results indicate that the proposed method has better highway traffic flow forecasting performance and is suitable for short-term highway traffic flow forecasting.

Key words: highway, traffic flow forecasting, adaptive dynamic particle swarm optimization algorithm, least squares support vector machines
