Safety of transport and also passengers'comfort depend on maintenance level of track surface (railway track, road pavement etc.), however, that maintenance technology have developed independently in railway engineering field and highway engineering field. Final objective of this study is to develop estimation and control system for surface irregularity which can be applied generally both on railway track and road pavement.In this study as the preparatory srep for achieving the former objective, the authors review whole maintenance system in highway (inclyding expressway) and railway (including Shinkansen) from the view of low, phenomenam, technology, operation, organization, economy etc., and find the common systematic flow of maintenance and future technical research points. Then, authors clarify them by following categories, 1) indices of track surface condition 2) characteristics of irregularity process 3) effectiveness of track maintenance etc.

轨道表面（铁路轨道、路面等）的养护水平决定着运输的安全和乘客的舒适度，而养护技术在铁路工程领域和公路工程领域都是独立发展起来的。本研究的最终目标是开发一套可广泛应用于铁路轨道和道路路面的路面不平整度评估与控制系统。本文从低、现象、技术、运营、组织、经济等方面对高速公路（含高速公路）和铁路（含新干线）的养护体系进行了梳理，找出了养护的系统共性流程和今后的技术研究要点。在此基础上，从轨道表面状况指标、不平整过程特征、轨道养护效果等方面进行了阐述。
