摘　　要：在论述运行速度概念的基础上分析影响运行速度的因素,建立运行速度预测模型并运用运行速度评价高速公路线形指标连续性的标准,提出运用运行速度来对高速公路线形指标进行校核与验证的方法。该方法能够很好地优化线形,保证高速公路线形指标的连续性,提高高速公路的安全性。It has discussed the concept of traversal speed, analyzes the influencing factor of traversal speed, and puts forward the forecast model of traversal speed and the criterion used to evaluate the expressway line consistency and the method of validating the expressway alignment based on traversal speed. With this means technicians can optimize the expressway alignment, guarantee the consistency and appraise the security of road alignment.

关 键 词：运行速度 预测模型 线形连续性 高速公路
