分析了现有公路功能分类存在的不足问题和当前公路功能复杂化的发展挑战,以苏南地区路网规划运营情况进行剖析,阐述公路功能分类研究的必要性。借鉴发达国家和地区公路功能分类理论研究和实践经验,结合我国公路发展环境和要求,以江苏为例,提出了与新型城镇化相应的公路功能分类体系,并结合苏虞张公路历次改建对公路功能分类应用进行了例证,最后对公路管理事权划分、公路规划、设计标准、养护管理标准都提出了进一步的研究展望。
This paper analyzes the existing problems of the existing road functional classification and the development challenges of the current complicated road functions. It analyzes the road network planning and operation in southern Jiangsu Province and expounds the necessity of the research on the road functional classification. Based on the theoretical research and practical experience of highway functional classification in developed countries and regions and with the development environment and requirements of the highway in our country, taking Jiangsu as an example, this paper proposes a classification system of highway functions corresponding to the new urbanization. The application of functional classification is illustrated. Finally, further research prospects are proposed for the division of highway management authority, highway planning, design standards and maintenance management standards.
