Based on the most widely used ALINEA (asservissement linéaire d’entrée autoroutière) algorithm in the ramp metering field, this paper optimizes the algorithm by using a wavelet neural network algorithm to predict traffic flow and consider the problem of inflow reduction in multi-lane traffic. For the multi-ramp cooperative control problem, the redundancy time is taken as the main index. The classifier’s design is based on pattern recognition theory. The important nodes are identified by K-means algorithm. The improved ALINEA algorithm is used to implement ramp control for important nodes. By controlling the key nodes of the expressway, the traffic efficiency of the expressway system is improved.
