摘　　要：在分析城郊公路与市政道路服务功能区别的基础上,论述了城郊公路实施市政化改造过程中横断面设计阶段的基本原则以及决策主要影响要素,明确实施市政化改造后道路应以市政用途为主导,同时建议在横断面设计阶段确定一级及以上等级公路改造后采用4幅及2幅路、二级及以下等级公路改造后采用3幅及单幅路;最后推荐了各车道宽度.On the basis of analyzing the difference of service function between the suburban highway and municipal road,the basic principle of cross section design stage and the main influencing factors of decision making in the implementation of urbanization reconstruction of suburban highway are discussed.It is clear and definite that the highways after urbanized and reconstructed should be dominated by the municipal use.And at the same time,it is suggested that Grade I and above highways are determined to be the four-carriageway roads and tow-carriageway roads,and Grade II and below highways to be the three-carriageway roads and single-carriageway roads after reconstructed in the stage of cross section design.Finally,each carriageway width is recommended.
