摘要
行程时间预测在交通和物流规划中具有重要的作用.传统方法大部分是针对单一路段的行程时间进行短期预测.考虑了一个与传统行程时间预测不同的背景,研究物流车队行程时间预测问题.结合人工神经网络的学习能力和支持向量基对复杂非线性预测的处理能力,提出了一种基于支持向量基和人工神经网络相结合的方法,对物流规划中车辆行程时间进行有效的预测.把得到的结果和真实值比较,说明所提出的预测方法是可行和有效的.
Travel time prediction plays an important role in transportation and logistics planning. Most of the work done so far is aiming at the development of the short-term prediction methods for the single road of the transportation systems. In this paper the travel time prediction of vehicle fleets in logistic com- panies is considered, which is a different scenario from the conventional transportation sector~ one. Com- bining the good learning ability of neural network （NN） and the strong nonlinear forecasting ability of support vector machine （ SVM）, a new approach is proposed for the time prediction of the long-range trips in a logistics fleets, based on the NN and SVM. The comparisons between the prediction values and the real values prove that the proposed approach is feasible and effective.
