摘　　要：针对常规的高速公路布线快速选择主要根据实地勘测的数据建立评估模型,存在忽略信息化空间数据误差对选择结果造成的影响,致使选择结果的可靠度较低问题,提出信息化背景下的高速公路布线快速选择方法研究。首先对信息化背景下的高速公路布线数据进行预处理,并采用一次变换的方法对空间数据误差进行修正;然后初步选择布线方案的综合指标,据此建立高速公路布线快速选择模型;最后计算模型的指标权重对模型进行完善,将数据导入模型获得高速公路布线快速选择结果。结果表明,所提出方法应用后得出的快速选择结果可靠度较高,平均可靠度为0.979,应用效果较好,能满足高速公路建设的现实需求。In the conventional fast selection of highway route,an evaluation model is mainly established based on field survey data,which ignores the impact of information technology spatial data errors on the selection results,resulting in low reliability of the selection results.Therefore,a research on fast selection methods for highway route under the background of information technology is proposed.Firstly,the highway route data under the background of informatization was preprocessed,and a one-time transformation method was used to correct spatial data errors.Based on the comprehensive indicators of the preliminary selection of route schemes,a fast selection model for highway route is established.Finally,the indicator weights of the model are calculated to improve the model,and the data is imported into the model to obtain a quick selection result for highway routing.The results show that the fast selection results obtained by the proposed method have high reliability,with an average reliability of 0.979.The application effect is good and can meet the practical needs of highway construction.
