刍议公路几何设计中的相关问题

公路线形是道路的骨架,也是命脉,因此线形几何设计是公路最为关键的组成部分,其不仅是包含平面线形、纵断面线形和横断面的三维立体线形设计,也是包含行车速度或时间在内的四维线形设计。此文从与道路几何线形设计相关的汽车运动学、行驶时间阀值和驾驶员心理学等问题进行了深入的分析研究,并对回旋线参数取值和S型曲线超高值计算问题进行了剖析,为公路设计者提供参考。

Related Issues on the Highway Geometric Design

Highway linear is the skeleton of the road, but also the lifeblood, so linear geometric design is the most critical part of the highway, which is not only designed to contain three-dimensional linear plane linear, linear and cross section of the profile, but also includes traffic speed dimensional or time linear design. From the geometric alignment dcsign and road-related car kinematics, travel time threshold and driver psychology issues in-depth analysis and research, and the cyclotron curve parameter values and ultra-high-value S-curve analysis issues provide reference for hi ghway designers.
