摘要:

车辆油耗是道路建设后评价的重要指标之一,同时也是道路路面设计、加油站选址、路径选择等问题的决策依据.传统的车辆油耗估计主要采用回归建模的方式,本文基于决策树数据挖掘方法给出了一种车辆油耗的估计模型.首先,利用主成分分析法获取影响车辆油耗的关键因素;其次,基于改进的C4.5 决策树构建车辆油耗估计模型;最后,结合1组高速公路场景下车辆油耗的典型样本数据,对本文模型进行验证,通过对车辆油耗预测值与真实值的误差分析,表明本文模型的有效性和实用性.

Abstract:

Vehicle fuel consumption is one of the important indicators of road construction post-evaluation. At the same time, it is the decision basis for pavement design, the location of gas stations, route choice and so on. Traditional vehicle fuel consumption evaluation mainly uses the method of constructing the regression model, and a vehicle fuel consumption estimation model based on decision tree and data mining is studied in this paper. Namely: firstly, the key factors affecting the vehicle fuel consumption are obtained using principal component analysis method; secondly, the vehicle fuel consumption estimation model is built based on the improved C4.5 decision tree; finally, validate the model presented in this paper combined with a representative sample data of vehicle fuel consumption at freeway scene. By analyzing error of vehicle fuel consumption estimated value and the real value, it shows the effectiveness and practicality of the proposed model.

Key words: highway transportation, fuel consumption evaluation, data mining, C4.5 decision tree algorithm, principal component analysis
