It would be the powerful theory base and evidence for alleviating congestion. In this dissertation, characteristics and effected factors of urban traffic congestion were generally analyzed and evaluation measures of congested traffic and normal traffic were reviewed. An index-system of congestion measures adapting to urban traffic was set up in which road characteristic, decision-making, perceptivity of citizen travel and economic-society adaptability were considered. A method of"classify status first, evaluate trend later"was found out according to analysis of all existing comprehensive evaluation methods.

First, the traffic flow time series chaotic feature is extracted by chaos theory. pretreatment for traffic flow time series, and the wavelet neural networks model was build by this. Second, the chaotic mechanism and the chaotic probability is described. Based on chaotic learning algorithm, and the wavelet neural networks fast learning algorithm of traffic flow time series is designed based on chaotic algorithm. Last, a single-step and multi-step prediction of traffic flow chaotic time series is researched by BP neural networks, wavelet neural networks and wavelet neural networks based on chaotic algorithm. The results showed that the wavelet neural networks predictive performance is better than the BP networks and the wavelet neural networks by the simulation results and root-mean-square value.

首先，通过混沌理论提取了交通流量时间序列的混沌特征，并在此基础上建立了小波神经网络交通流量时间序列模型；接着，阐述了混沌学习算法的混沌机理、混沌产生的概率，设计了基于混沌算法的小波神经网络交通流量混沌时间序列快速学习算法；最后利用交通流量混沌时间序列对BP网络、非混沌算法的小波神经网络以及基于混沌算法的小波神经网络进行了单步预测和多步预测，并对预测结果的仿真图和真实值与预测值的方均根进行了比较，结果表明基于混沌学习算法的小波神经网络的预测性能明显优于应用BP网络和非混沌算法的小波神经网络。

Xingyi City is located at the junction of Guizhou, Yunnan and Guangxi provinces and autonomous region, connecting Yunnan in the west, Guangxi in the south, over 300km away from Guiyang and Kunming and 500km away from Nanning. It is one key city of the Nanning, Guiyang and Kunming Economic Area, the commodity distributing center and the traffic hub. After several years of construction, the modern three-dimensional traffic net with aviation, railway, road and water carriage has been formed in Xingyi City. The convenient traffic makes Xingyi become the key traffic hub southwestward to the sea.
