一、前言在高速公路交通量预测过程中,往往需要采集、分析和处理大量基础数据信息,并且需要对模型中一系列参数进行调试,计算工作量相当之大是手工难以胜任的。因此,借助于信息技术,并在数据库的支持下进行分析和计算是一种有效的解决方案。目前对高速公路交通量预测技术手段的 I. Preface It is often necessary to collect, analyze and process large amounts of basic data information during highway traffic forecasting. It is also necessary to debug a series of parameters in the model. It is hard to do manual work due to the considerable workload. Therefore, it is an effective solution to analyze and calculate with the aid of information technology and database. The current highway traffic prediction techniques
