Besides the latest hot models, the show featured astounding feats of braking and acceleration, and a special ramp was built to demonstrate the hill-climbing prowess of the different cars.
The length design of the acceleration lane depends on not only traffic speed but also traffic volume of the main line and ramp of expressway interchanges.
高速公路加速车道的设置长度不仅取决于主路及匝道的设计速度，还与主路及匝道的交通量有关。

This paper presents a new design philosophy on acceleration lane that the traffic volumes on main line of expressway and on ramp are considered in the computation of the acceleration lane length.
