汽车保有量预测对城市交通的发展方向、城市交通的控制管理、城市道路的建设情况等都有直接的参考意义。本文通过分析影响城市汽车保有量的因素,通过参考部分参考文献,城区人口总数人均GDP、公路客运量等8个指标,首先采用主成分分析法将8个因素进行分析,然后建立BP神经网络模型对湖南省2006到2008年汽车保有量进行预测,预测结果分别为98.93万辆、122.18万辆、137.03万辆,与汽车保有量实际值94.64万辆、121.72万辆、142.67万辆很接近,预测精度比较高。这表明BP神经网络具有很强的学习与泛化能力,用于汽车保有量预测的可行性与有效性。
汽車保有量預測對城市交通的髮展方嚮、城市交通的控製管理、城市道路的建設情況等都有直接的參攷意義。本文通過分析影響城市汽車保有量的因素,通過參攷部分參攷文獻,城區人口總數人均GDP、公路客運量等8箇指標,首先採用主成分分析法將8箇因素進行分析,然後建立BP神經網絡模型對湖南省2006到2008年汽車保有量進行預測,預測結果分彆為98.93萬輛、122.18萬輛、137.03萬輛,與汽車保有量實際值94.64萬輛、121.72萬輛、142.67萬輛很接近,預測精度比較高。這錶明BP神經網絡具有很彊的學習與汎化能力,用于汽車保有量預測的可行性與有效性。

Prediction of car ownership has a direct reference significance for the the development of urban transportation and con struction of urban roads. By analyzing the impact factors of urban auto possession,this paper first analyzes 8 indicators such as urban population,GDP, road passenger traffic and so on determined by some references, then establish BP neural network model to predicts the vehicles possession in Hunan Province from 2006 to 2008. The figures of prediction is 989,300, 1,221,800 and 1,370,300 respectively in 2006, 2007 and 2008, which is very close to the real ownership of 946,400,1,217,200 and 1,426, 700 respectively. It shows the prediction is very accurate. This suggests that the BP neural network has very strong learning and generalization ability and can be employed in prediction of vehicle possession effectively.
