一、线形设计与透视图公路设计应满足汽车运动学和力学的要求。为使汽车安全地转弯,就有与速度相适应的超高、曲线半径及缓和曲线等要求;为使驾驶员安全地在发现对向来车和路面上的障碍物时,能从容地停车、绕行或错车而不致碰撞,就有相应的视距要求;为使汽车能克服坡度并不致将速度降得过低,就有最大纵
First, the linear design and perspective Road design should meet the requirements of automotive kinematics and mechanics. In order to make the car turn safely, there are requirements such as ultra-high speed, curve radius and easing curve, etc. In order to enable the driver to safely stop the vehicle when it finds the opposite car and the obstacle on the road, Line or wrong car without collision, there is a corresponding line of sight requirements; in order to make the car to overcome the gradient does not cause the speed dropped too low, there is the maximum vertical
