摘　　要：对于一级公路接入口设计,现有标准规范的规定和要求不尽详细和完善。根据西南地区一级公路道路交通特点,对经过村镇路段的接入口设计进行了系统研究,提出了接入口间距控制建议值和实现方法、各相交道路等级对应的接入口几何设计控制指标建议值和实现方法、接入口视距保证的标准和实现方法。The current standards and specifications for the access design of the first-grade highway are not perfect. Considering road and traffic characteristics of the first-grade highway in southwest area of China, the access design of section crossing village and town is systemically studied. The recommended values of distance control between accesses and its implementation, the recommended values of geometric design control index for accesses corresponding to various levels of intersected roads and its implementation, as well as standards for sight distance guarantee for accesses and its .implementation are proposed.
