摘要:针对城镇化快速发展给道路建设带来的新要求,总结了大城市发展中对城市人口、用地控制不严造成城市交通拥堵、绿化减少等城市病的经验与教训。重点论述了发展小城镇是城市发展的需要与出路,以及发展小城镇对城镇道路建设的要求,并提出了小城镇内部道路交通设计的新构思,如绿色交通、节约用地、以人为本、人与自然和谐发展等。相应提出一套包括内部道路类别与等级、路网布局、道路断面及宽度、交叉口交通组织设计的小城镇道路交通设计标准。最后提出小城镇外部公路与其附近连络干路应采取简易立交,高速公路收费站出入口应增加信号灯,扩大渠化,增设快速公交站点等建议。

Abstract: Focusing on new demands stemming from rapid development of urbanization, this paper summarizes the experiences and lessons learned from urban development of other major cities. These include a lack of strict control of land-use and population which causes traffic congestion and reduction of green spaces. The paper also discusses the development of small towns as a need and outlet of urbanization, the relationship between urban road building and the development of small towns, and a new concept for inner road traffic design in small towns, such as green traffic, optimal land utilization, human-oriented development, harmonious development between human and the nature, etc. Meanwhile, a serial of design standard for town road design is advanced, including road classification, network layout, road section and width, traffic organizing at intersections Finally, this paper suggests how to build outer roads for small towns, such as overpasses on outer roads and nearby roads, increasing signal lights at highway toll gate entrances, expanding canal traffic, and increasing stops for high-speed buses.
