摘要
公路网交通运行性能指标汇聚方法是计算公路网性能指标、提高公路网交通运行效率与管理水平、改善路网交通运行状况的重要手段。文章结合我国公路网交通运行性能指标发展现状,给出了4类指标汇聚方法,包括算术平均法、加权平均法、直接累加法和累加相除法,并采用实际公路网数据对各种汇聚方法进行实例计算。
Aggregation method of performance measures is a significant means to compute the performance measures of highway networks,improve the effectiveness of highway network operations and management,and enhance the condition of road transportation.Based on the current condition of performance measurement for Chinese highway networks,four aggregation methods are proposed,including the arithmetic average method,the weighted average method,the straight summation method,and the summation and division method.The four methods are then demonstrated using the real world highway network data.
