  要:结合高速公路现有服务设施功能特点,将服务设施分为三类。通过综合论证各类服务设施间距的控制因素,选择及时事故救援距离、低油量安全行驶距离和基于驾驶员自控下的疲劳特性三个关键因素分别作为三类服务设施间距的控制因素,分别建立服务设施间距计算模型,通过对14个典型高速公路服务区进行咨询调查和回归分析,对模型中的相关参数进行深入研究,确定了参数的合理取值,并提出三类服务设施的推荐间距和布置类型。研究表明,A类服务设施间距推荐值为60120kmB类服务设施间距推荐值为45kmC类服务设施间距推荐值为68km

AbstractCombined with the characteristics of the existing service facilitiesthe service facilities are divided into three categories. Through the comprehensive demonstration of the control factors of various service facilitiesthree key factors were selected to determine the parameters of the modelthe reasonable value of the parametersand the recommended spacing and layout of the three types of service facilitieswere established. The research shows that the recommended value of the distance between class a service facilities was 60120kmthe recommended value of 120km class service facilities was 45kmand the recommended value of C services was 68km.
